What is ASIC Design?
ASIC (Application-Specific Integrated Circuit) Design involves creating custom silicon chips tailored for particular functions, such as AI acceleration or signal processing. It encompasses the entire process from specification and RTL coding to physical design and verification, focusing on achieving high performance, low power, and area efficiency. Key characteristics include deep hardware-software co-design, use of EDA tools, and rigorous testing to ensure functionality and manufacturability.
