What is a CPU verification engineer?

A CPU Verification Engineer is responsible for ensuring that a CPU design functions correctly before manufacturing. They develop and execute test plans using simulation, formal verification, and other methodologies to validate processor behavior against specifications. This role requires knowledge of hardware description languages (like Verilog or VHDL), verification languages (such as SystemVerilog UVM), and debugging tools. CPU Verification Engineers collaborate with architects and designers to identify and resolve design issues. Their work is critical in catching bugs early, improving performance, and ensuring the reliability of modern processors.
