You ensure functional and performance excellence at top level for all graphic blocks by advancing verification methodologies, tools, and automation to improve efficiency and quality, maintain technical documents, and create sophisticated test scenarios that stress full graphics pipelines (including command processing, front-end, shader cores, rasterization, and fixed-function units), covering corner cases, performance-sensitive paths, and real-world workloads. You help develop and maintain scalable verification testbenches using SystemVerilog and C++, developing test code in parallel with RTL, and applying constrained-random testing, coverage-driven verification, and assertion-based techniques to validate complex graphics and compute behavior.
