- AMDEasySoftware EngineerBuild a UVM testbench: driver, monitor, scoreboard and coverage-driven closure
A hardware design verification question on building a SystemVerilog UVM testbench for an RTL block. It covers agents, drivers, monitors and scoreboards, checking results that may leave out of order, catching missing outputs, and using code and functional coverage to steer constrained-random stimulus toward sign-off.
