Use this trick to Save time : HDL Simulation through defining clock
Why is this trick useful? Defining a clock in your simulation can save you time during simulation because you don't have to manually generate the clock signal in your simulation environment. Wanted to know how to define and force clock to simulate your digital system. Normally define clock used to simulate system with clock input. But I am telling you this trick for giving values to input ports other than clock. It will help you to save time in simulation because you do not need to force values to input ports every time. Lets brief What we did - gave some clock frequency to input A, like we gave 100. Than we made Half the frequency of clock to 50 and gave it to Input B. In similar way if we have 3rd input too we goanna half the frequency again to 25 and would give to next input.

MIT engineers grow “high-rise” 3D chips
New Post has been published on https://thedigitalinsider.com/mit-engineers-grow-high-rise-3d-chips/
MIT engineers grow “high-rise” 3D chips
The electronics industry is approaching a limit to the number of transistors that can be packed onto the surface of a computer chip. So, chip manufacturers are looking to build up rather than out.
Instead of squeezing ever-smaller transistors onto a single surface, the industry is aiming to stack multiple surfaces of transistors and semiconducting elements — akin to turning a ranch house into a high-rise. Such multilayered chips could handle exponentially more data and carry out many more complex functions than today’s electronics.
A significant hurdle, however, is the platform on which chips are built. Today, bulky silicon wafers serve as the main scaffold on which high-quality, single-crystalline semiconducting elements are grown. Any stackable chip would have to include thick silicon “flooring” as part of each layer, slowing down any communication between functional semiconducting layers.
Now, MIT engineers have found a way around this hurdle, with a multilayered chip design that doesn’t require any silicon wafer substrates and works at temperatures low enough to preserve the underlying layer’s circuitry.
In a study appearing today in the journal Nature, the team reports using the new method to fabricate a multilayered chip with alternating layers of high-quality semiconducting material grown directly on top of each other.
The method enables engineers to build high-performance transistors and memory and logic elements on any random crystalline surface — not just on the bulky crystal scaffold of silicon wafers. Without these thick silicon substrates, multiple semiconducting layers can be in more direct contact, leading to better and faster communication and computation between layers, the researchers say.
The researchers envision that the method could be used to build AI hardware, in the form of stacked chips for laptops or wearable devices, that would be as fast and powerful as today’s supercomputers and could store huge amounts of data on par with physical data centers.
“This breakthrough opens up enormous potential for the semiconductor industry, allowing chips to be stacked without traditional limitations,” says study author Jeehwan Kim, associate professor of mechanical engineering at MIT. “This could lead to orders-of-magnitude improvements in computing power for applications in AI, logic, and memory.”
The study’s MIT co-authors include first author Ki Seok Kim, Seunghwan Seo, Doyoon Lee, Jung-El Ryu, Jekyung Kim, Jun Min Suh, June-chul Shin, Min-Kyu Song, Jin Feng, and Sangho Lee, along with collaborators from Samsung Advanced Institute of Technology, Sungkyunkwan University in South Korea, and the University of Texas at Dallas.
Seed pockets
In 2023, Kim’s group reported that they developed a method to grow high-quality semiconducting materials on amorphous surfaces, similar to the diverse topography of semiconducting circuitry on finished chips. The material that they grew was a type of 2D material known as transition-metal dichalcogenides, or TMDs, considered a promising successor to silicon for fabricating smaller, high-performance transistors. Such 2D materials can maintain their semiconducting properties even at scales as small as a single atom, whereas silicon’s performance sharply degrades.
In their previous work, the team grew TMDs on silicon wafers with amorphous coatings, as well as over existing TMDs. To encourage atoms to arrange themselves into high-quality single-crystalline form, rather than in random, polycrystalline disorder, Kim and his colleagues first covered a silicon wafer in a very thin film, or “mask” of silicon dioxide, which they patterned with tiny openings, or pockets. They then flowed a gas of atoms over the mask and found that atoms settled into the pockets as “seeds.” The pockets confined the seeds to grow in regular, single-crystalline patterns.
But at the time, the method only worked at around 900 degrees Celsius.
“You have to grow this single-crystalline material below 400 Celsius, otherwise the underlying circuitry is completely cooked and ruined,” Kim says. “So, our homework was, we had to do a similar technique at temperatures lower than 400 Celsius. If we could do that, the impact would be substantial.”
Building up
In their new work, Kim and his colleagues looked to fine-tune their method in order to grow single-crystalline 2D materials at temperatures low enough to preserve any underlying circuitry. They found a surprisingly simple solution in metallurgy — the science and craft of metal production. When metallurgists pour molten metal into a mold, the liquid slowly “nucleates,” or forms grains that grow and merge into a regularly patterned crystal that hardens into solid form. Metallurgists have found that this nucleation occurs most readily at the edges of a mold into which liquid metal is poured.
“It’s known that nucleating at the edges requires less energy — and heat,” Kim says. “So we borrowed this concept from metallurgy to utilize for future AI hardware.”
The team looked to grow single-crystalline TMDs on a silicon wafer that already has been fabricated with transistor circuitry. They first covered the circuitry with a mask of silicon dioxide, just as in their previous work. They then deposited “seeds” of TMD at the edges of each of the mask’s pockets and found that these edge seeds grew into single-crystalline material at temperatures as low as 380 degrees Celsius, compared to seeds that started growing in the center, away from the edges of each pocket, which required higher temperatures to form single-crystalline material.
Going a step further, the researchers used the new method to fabricate a multilayered chip with alternating layers of two different TMDs — molybdenum disulfide, a promising material candidate for fabricating n-type transistors; and tungsten diselenide, a material that has potential for being made into p-type transistors. Both p- and n-type transistors are the electronic building blocks for carrying out any logic operation. The team was able to grow both materials in single-crystalline form, directly on top of each other, without requiring any intermediate silicon wafers. Kim says the method will effectively double the density of a chip’s semiconducting elements, and particularly, metal-oxide semiconductor (CMOS), which is a basic building block of a modern logic circuitry.
“A product realized by our technique is not only a 3D logic chip but also 3D memory and their combinations,” Kim says. “With our growth-based monolithic 3D method, you could grow tens to hundreds of logic and memory layers, right on top of each other, and they would be able to communicate very well.”
“Conventional 3D chips have been fabricated with silicon wafers in-between, by drilling holes through the wafer — a process which limits the number of stacked layers, vertical alignment resolution, and yields,” first author Kiseok Kim adds. “Our growth-based method addresses all of those issues at once.”
To commercialize their stackable chip design further, Kim has recently spun off a company, FS2 (Future Semiconductor 2D materials).
“We so far show a concept at a small-scale device arrays,” he says. “The next step is scaling up to show professional AI chip operation.”
This research is supported, in part, by Samsung Advanced Institute of Technology and the U.S. Air Force Office of Scientific Research.

Improving AI Inference Performance with Hardware Accelerators
New Post has been published on https://thedigitalinsider.com/improving-ai-inference-performance-with-hardware-accelerators/
Improving AI Inference Performance with Hardware Accelerators
As artificial intelligence (AI) continues to permeate various industries, the demand for efficient and powerful AI inference has surged. AI inference, the process of running trained machine learning models to make predictions or decisions, is computationally intensive and often constrained by the performance of the underlying hardware.
Enter hardware accelerators[1]—specialized hardware designed to optimize AI inference, providing significant improvements in flexibility, performance, and iteration time.
AI inference is the process of applying a trained machine learning model to new data in order to make predictions or decisions. With the growing demand for AI applications across industries, achieving real-time performance during inference is crucial.
Hardware accelerators, such as GPUs (Graphics Processing Units), NPUs (Neural Processing Units), FPGAs (Field-Programmable Gate Arrays), and ASICs (Application-Specific Integrated Circuits) play a significant role in enhancing AI inference performance by providing optimized computational power and parallelism.
This article explores the different types of hardware accelerators, their architecture, and how they can be leveraged to improve AI inference performance. This article explores how hardware accelerators enhance AI inference and the impact they have on modern AI applications.
AI Inference challenges
AI inference typically involves performing a large number of mathematical operations, such as matrix multiplications, which are computationally intensive.
Traditional CPUs, although powerful, are not optimized for these specific types of workloads, leading to inefficiencies in power consumption and speed. As AI models become more complex and data sets larger, the need for specialized hardware to accelerate inference has become apparent.
In AI inference, the balance between compute power and memory bandwidth is critical for optimal performance. Compute Power refers to the processing capability of the hardware, which handles the mathematical operations required by the AI model.
High compute power allows for faster processing of complex models. Memory Bandwidth is the speed at which data can be transferred between memory and the processing units. The computational requirements for training state-of-the-art Convolutional Neural Networks (CNNs) and Transformer models have been growing exponentially.
This trend has fueled the development of AI accelerators designed to boost the peak computational power of hardware. These accelerators are also being developed to address the diverse memory and bandwidth bottlenecks associated with AI workloads, particularly in light of the fact that DRAM memory scaling is lagging behind advancements in compute power as shown in Fig 1.
Fig 1. Comparing the evolution of # parameters of CNN/Transformer models vs the Single GPU Memory [6]
Fig 2. Computer (FLOPs) vs Memory Bandwidth (/Inference) for different CNN architectures [7]
Fig 2 and 3, shows the computer vs memory bandwidth of the popular AI models[6-7]. Even with high compute power, if memory bandwidth is insufficient, the processors may spend time waiting for data, leading to underutilization of compute resources. Ensuring that memory bandwidth matches the compute demands of the AI model is essential for avoiding bottlenecks and maximizing inference performance.

Hardware accelerators
Hardware accelerators, such as GPUs, NPUs, FPGAs, and ASICs, offer a range of deployment options that cater to diverse AI applications. These accelerators can be deployed on-premises, in data centers, or at the edge, providing flexibility to meet specific needs and constraints.
The primary advantage of hardware accelerators is their ability to significantly boost computational performance. GPUs, with their parallel processing capabilities, excel at handling the massive matrix operations typical in AI inference. This parallelism allows for faster processing of large datasets and complex models, reducing the time required to generate predictions.
NPUs, specifically designed for AI workloads, offer even greater performance improvements for certain deep learning tasks. By optimizing the hardware for matrix multiplications and convolutions, NPUs can deliver superior throughput and efficiency compared to general-purpose processors. The architecture of hardware accelerators plays a crucial role in their ability to enhance AI inference performance.
Below, we outline the key architectural features of GPUs, NPUs, FPGAs, and ASICs.
Fig 4. Overview of Hardware architecture for Hardware Accelerators
Graphics Processing Units (GPUs)
GPUs are widely used for AI workloads due to their ability to perform parallel computations efficiently. Unlike CPUs, which are optimized for sequential tasks, GPUs can handle thousands of parallel threads, making them ideal for the matrix and vector operations common in deep learning.
The GPU architecture is designed with thousands of computer units along with scratch memory and control units, enabling highly parallel data processing. Modern GPUs, such as NVIDIA’s A100, are specifically designed for AI workloads, offering features like tensor cores that provide further acceleration for AI operations.
The architecture of a GPU consists of multiple cores, each capable of executing thousands of threads simultaneously. Modern GPUs include specialized cores, such as tensor cores, which are designed specifically for deep learning operations. The memory bandwidth and large register files of GPUs enable efficient handling of large datasets.
Neural Processing Units (NPUs)
NPUs are custom accelerators designed specifically for neural network processing. NPUs are optimized for inference tasks, and they excel at handling large-scale AI models.
The architecture of NPUs contains multiple compute units that allow them to perform matrix multiplications and convolutions more efficiently than GPUs, particularly for models like convolutional neural networks (CNNs).
The architecture of an NPU allows for the efficient execution of matrix multiplications. NPUs include on-chip memory to reduce data transfer times and increase throughput. The array architecture is particularly effective for CNNs and other deep learning models.
Field-Programmable Gate Arrays (FPGAs)
FPGAs offer a unique advantage due to their reconfigurability. They contain millions of programmable gates that can be programmed to optimize specific tasks, such as AI inference, by tailoring the hardware to the specific needs of the application.
This makes FPGAs highly efficient for AI workloads, especially in scenarios where low latency is critical, such as in real-time systems. Companies like Xilinx and Intel offer FPGAs that can be configured to accelerate AI inference.
FPGAs are composed of a grid of configurable logic blocks connected by programmable interconnects. The flexibility of FPGAs allows them to be customized for specific AI workloads, optimizing both performance and power consumption. The ability to reprogram the logic blocks enables FPGAs to adapt to different neural network models as needed.
Application-Specific Integrated Circuits (ASICs)
ASICs are custom-designed chips optimized for a specific application or task. In the context of AI, ASICs are designed to accelerate specific neural network models. An example is Google’s Edge TPU, which is designed for fast and efficient AI inference on edge devices.
The main advantage of ASICs is their efficiency in terms of both power consumption and performance, but they lack the flexibility of FPGAs. ASICs are highly optimized for specific tasks, with a fixed architecture that is designed to maximize efficiency for those tasks.
In the case of AI inference, ASICs are designed to execute specific neural network models with minimal power consumption and maximum speed. This fixed architecture, while highly efficient, lacks the flexibility of FPGAs.
Optimization techniques
To fully leverage the capabilities of various hardware accelerators, different optimization techniques can be applied, each tailored to the strengths of specific hardware types:
Network Architecture Search (NAS): NAS is particularly valuable for customizing neural network architectures to suit specific hardware accelerators. For edge devices, NAS can craft lightweight models that minimize parameters while maximizing performance.
This is especially crucial for NPUs and ASICs, where designing architectures that efficiently utilize hardware resources is essential for optimizing performance and energy efficiency.
Quantization: Quantization involves reducing the precision of a model’s weights and activations, typically from floating-point to fixed-point representations. This technique is highly effective on NPUs, ASICs, and FPGAs, where lower precision computations can drastically improve inference speed and reduce power consumption.
GPUs also benefit from quantization, though the gains may be less pronounced compared to specialized hardware like NPUs and ASICs.
Pruning: Pruning reduces the number of unnecessary weights in a neural network, thereby decreasing the computational load and enabling faster inference. This technique is particularly effective for FPGAs and ASICs, which benefit from reduced model complexity due to their fixed or reconfigurable resources.
Pruning can also be applied to GPUs and NPUs, but the impact is most significant in environments where hardware resources are tightly constrained.
Kernel fusion: Kernel fusion combines multiple operations into a single computational kernel, reducing the overhead of memory access and improving computational efficiency.
This optimization is especially beneficial for GPUs and NPUs, where reducing the number of memory-bound operations can lead to significant performance improvements. Kernel fusion is less applicable to FPGAs and ASICs, where operations are often already highly optimized and customized.
Memory optimization: Optimizing memory access patterns and minimizing memory footprint are critical for maximizing the available bandwidth on hardware accelerators.
For GPUs, efficient memory management is key to improving throughput, particularly in large-scale models. NPUs also benefit from memory optimization, as it allows for more efficient execution of neural networks. FPGAs and ASICs, with their specialized memory hierarchies, require careful memory planning to ensure that data is efficiently accessed and processed, thereby enhancing overall inference performance.
AI model deployment challenges
Deploying AI models on hardware accelerators presents several challenges, particularly in terms of flexibility, iteration time, and performance. Each type of accelerator—GPUs, NPUs, FPGAs, and ASICs—poses unique considerations in these areas.
Fig 5. Different trade-offs AI Model deployment on accelerators
Flexibility: Flexibility is vital for supporting the latest AI models and adapting to evolving frameworks. GPUs, with their general-purpose architecture, offer the highest flexibility among accelerators, making them well-suited for rapidly integrating new models and frameworks.
NPUs, while more specialized, also provide a good balance of flexibility, particularly for neural network tasks, though they may require some adjustments for new operations or model types.
FPGAs are reconfigurable, allowing for custom adjustments to support new models, but this reconfiguration can be complex and time-consuming. ASICs, being custom-designed for specific tasks, offer the least flexibility; any change in model architecture or framework may require a new chip design, which is costly and time-intensive.
The challenge, therefore, lies in ensuring that the deployment environment can integrate advancements without extensive reconfiguration, especially in less flexible hardware like ASICs and FPGAs.
Iteration time: Iteration time, or the speed at which improved AI models can be deployed, is crucial for maintaining the effectiveness of AI systems. GPUs excel in this area due to their compatibility with a wide range of development tools and frameworks, allowing for faster model optimization and deployment.
NPUs also support relatively quick iteration times, especially when deploying models tailored for neural network tasks. However, the application of optimization techniques like quantization and pruning can add complexity, requiring thorough validation to ensure that the model meets performance and key performance indicators (KPIs) post-deployment.
FPGAs, though powerful, often have longer iteration times due to the need for reconfiguration and hardware-specific optimization. ASICs present the greatest challenge in iteration time, as any update or improvement to the model could necessitate redesigning the hardware, which is a slow and expensive process.
Performance: Performance is a key concern when deploying AI models on hardware accelerators. For GPUs, achieving optimal performance involves maximizing hardware resource utilization and efficiently scaling across multiple units, which can be managed relatively easily due to the mature ecosystem of tools available.
NPUs, designed specifically for AI workloads, generally achieve high performance with low latency and high throughput but may require fine-tuning to fully leverage their capabilities. FPGAs, with their customizability, can achieve exceptional performance for specific tasks but often require manual tuning, including custom kernel development and modifications to fully optimize the model.
ASICs deliver the best performance per watt for specific tasks due to their tailored design, but achieving this performance involves significant upfront design work, and any deviation from the initial model can severely impact performance.
These challenges underscore the importance of a carefully considered deployment strategy tailored to the specific hardware accelerator being used. By understanding and addressing the unique flexibility, iteration time, and performance challenges of GPUs, NPUs, FPGAs, and ASICs, organizations can fully leverage the potential of hardware accelerators for AI model deployment.
Performance comparison
When evaluating the performance of various hardware accelerators, it is crucial to consider several key factors, including throughput, latency, power consumption, scalability, and cost. Below is an updated summary of these performance metrics for GPUs, NPUs, FPGAs, and ASICs.
Throughput: GPUs are known for their high throughput, making them ideal for large-scale AI models and batch-processing tasks. NPUs, designed specifically for AI workloads, also offer high throughput but are optimized for neural network processing. FPGAs and ASICs, while capable of high throughput, are typically employed in scenarios where low latency is more critical than raw throughput.
Latency: FPGAs and ASICs generally offer lower latency compared to GPUs and NPUs, making them well-suited for real-time applications. FPGAs are particularly valuable because of their reconfigurability, allowing them to be tailored for low-latency inference tasks. ASICs, being custom-designed for specific tasks, are also optimized for minimal latency.
Power Consumption: In terms of energy efficiency, ASICs are the most power-efficient due to their specialized design. NPUs, which are also designed for AI tasks, offer better energy efficiency compared to general-purpose GPUs.
FPGAs tend to consume more power than ASICs but are generally more power-efficient than GPUs, especially when configured for specific tasks. GPUs, while offering high performance, are typically less power-efficient, but their use can be justified in scenarios where their computational power is necessary.
Scalability: All four types of accelerators offer scalability, but the approaches differ. GPUs are widely used in data centers, where multiple units can be deployed in parallel to manage large-scale AI workloads. NPUs, with their specialized architecture, also scale well in distributed AI environments.
FPGAs provide flexibility and can be reconfigured to scale with the workload, while ASICs, though less flexible, offer scalable solutions when deployed in specific applications. Cloud providers often offer accelerator instances, allowing organizations to dynamically scale their AI infrastructure according to workload requirements.
Cost: ASICs are the most expensive to design and manufacture due to their custom nature, which requires significant upfront investment. FPGAs are more cost-effective for applications that require flexibility and reconfigurability.
GPUs, being general-purpose processors, are typically more affordable for a wide range of AI workloads, making them a popular choice for many applications. NPUs, though specialized, generally fall between GPUs and ASICs in terms of cost, offering a balance of efficiency and affordability depending on the use case.
Future trends
The future of AI inference hardware accelerators is poised for significant advancements, driven by the need for more specialized, efficient, and scalable architectures. Several emerging trends are shaping the development of next-generation hardware accelerators:
Heterogeneous computing: The future of AI hardware will likely involve a heterogeneous approach, combining multiple types of processors—such as CPUs, GPUs, NPUs, FPGAs, and ASICs—into a single system to leverage the strengths of each.
This approach allows for the dynamic allocation of workloads to the most appropriate hardware, optimizing performance, power consumption, and efficiency. Heterogeneous computing architectures are expected to become more prevalent as AI models continue to grow in complexity, requiring diverse hardware capabilities to meet different computational demands.
Innovations in software frameworks and tools will be critical to managing these complex systems and ensuring seamless integration between different types of accelerators.
Neuromorphic computing is an innovative approach inspired by the human brain’s architecture. Neuromorphic chips are designed to mimic the structure and function of biological neural networks, enabling AI inference with remarkably low power consumption and high efficiency.
These chips use spiking neural networks (SNNs), which process information in a way that resembles how neurons communicate in the brain—through spikes of electrical activity.
This approach can dramatically reduce energy usage compared to traditional digital processors, making neuromorphic chips ideal for battery-powered devices and other energy-constrained environments. Companies like Intel (with its Loihi chip) and IBM (with its TrueNorth chip) are leading the development of neuromorphic computing, aiming to bring brain-inspired computing closer to practical applications.
3D chip stacking, also known as 3D integration, is an emerging technology that involves stacking multiple layers of semiconductor chips vertically to create a single, densely packed unit.
This technique allows for greater integration of processing, memory, and communication resources, leading to significant improvements in performance, power efficiency, and form factor.
By reducing the distance that data needs to travel between different parts of the chip, 3D stacking can greatly reduce latency and increase bandwidth, making it a promising solution for AI inference tasks that require high throughput and low latency. The technology also enables more compact designs, which are essential for advanced AI applications in portable devices and edge computing.
Edge AI refers to the deployment of AI models directly on devices at the edge of the network, rather than relying on centralized cloud computing. As the demand for real-time processing in IoT devices, autonomous vehicles, and mobile applications continues to grow, edge AI is becoming increasingly important.
Specialized accelerators like Google’s Edge TPU are designed specifically for low-power AI inference on edge devices, enabling fast and efficient processing close to where data is generated.
These accelerators are optimized for tasks such as image recognition, natural language processing, and sensor data analysis, allowing for real-time AI applications without the need for constant connectivity to the cloud. The growth of edge AI is also driving innovations in energy-efficient hardware design, making it possible to deploy powerful AI capabilities in small, power-constrained devices .
Quantum computing for AI: Although still in its early stages, quantum computing holds the potential to revolutionize AI inference by leveraging quantum mechanics to perform computations at unprecedented speeds.
Quantum computers could solve certain types of problems much faster than classical computers, including those involving optimization, search, and sampling, which are common in AI.
While quantum hardware is not yet ready for widespread AI inference tasks, ongoing research and development suggest that quantum accelerators could eventually complement traditional hardware by handling specific, highly complex AI computations that are beyond the reach of current digital systems.
These trends indicate that the future of AI inference hardware will be marked by increasingly specialized and efficient architectures, tailored to meet the growing demands of AI applications across various domains.
By embracing these emerging technologies, the industry will be able to push the boundaries of what is possible in AI, driving new innovations and unlocking new possibilities for real-time, energy-efficient AI processing.
Conclusion
Hardware accelerators are revolutionizing AI inference by enhancing flexibility, performance, and iteration time. Their versatile deployment options, adaptability to different workloads, and future-proofing capabilities make them indispensable in modern AI infrastructure.
By delivering accelerated computation, improved energy efficiency, and scalability, hardware accelerators ensure that AI applications can meet the demands of today’s data-intensive and real-time environments. Furthermore, by reducing iteration time, they enable faster model development, real-time inference, and rapid prototyping, driving innovation and competitiveness in the AI landscape.
As AI continues to evolve, the role of hardware accelerators will only become more pivotal, unlocking new possibilities and transforming industries across the board. Hardware accelerators are essential for improving AI inference performance, enabling faster and more efficient processing of complex models.
By understanding the capabilities and limitations of different types of accelerators, such as GPUs, NPUs, FPGAs, and ASICs, developers can choose the right hardware for their specific AI applications. As the field continues to evolve, we can expect to see further innovations in accelerator technology, driving the next wave of AI advancements.

I'm sorry, just sent in 62 for the ask game because I'd overlooked that it's the amazing scifi thing!
Soooo 63?
(ID in ALT text)
okay so... you know whats really funny here. i think made this while for the first time polls popped up on tumblr. and i had this werid idea of like... "choose your adventure" kind of story telling. but... lets be honest i don't have much... time to draw all the options? but this is still like... a sort of darker AU which is deer to my heart. and till today i don't know if they should have a happy end or not. sokka got shipwrecked. and to make his situation even worse zuko poped up and and took a bite of him.
the whole siren idea is more based on the sinister one. the one drowning and eating seamen. and zuko is now out to eat sokka. i have some plot lines written out. -sokka playing with zuko a game of riddles to buy himself some more time -zuko being unable to stay in the sun so sokka has to decide if he lest him take shelter underneath his make shift raft or lure him out of there to burn him. at the end sokka does get saved and can escape for some time? because zuko did end up biting him. and now sokka cant stop hearing him in his head, and zuko can still follow him. so... watch out sokka! zuko is on his way to eat you up but i still don't know if he means it literally or in a more plessurable way...
#chip!ask#wip ask game#meremay au but its january#sokka#zuko#mere!zuko#i honestly... i do like zukos designe for this#not that it is visible here and it slightly changed later on#but he doesn't have a tail!#he does have legs but similar to jelly fish he can like extend appandeges out that are like his fins?#so yeha... he needs to be near water othervise he dreis out to quickly but... he can follow sokka on land.#sokka: hahah... i am screwed
