9. Design Exploration and Automation
Design exploration and automation are critical in VLSI design for navigating the complex design space and automating repetitive tasks, enhancing efficiency and quality. Key algorithms such as exhaustive search, greedy algorithms, and genetic algorithms facilitate optimal design configurations, while automation techniques like high-level synthesis and formal verification streamline the design flow. As VLSI designs grow in complexity, these methods continue to evolve and are increasingly essential for optimal design solutions.
