The testbench itself is implemented as a separate top-levelVerilog module. This module is responsible for generating input stimuli for the DUT, capturing its output, and comparing it with expected outputs. The testbench generates different input patterns and sequences to test different scenarios and...

Here, we have talked about how a simple testbench looks like. In real projects, there'll be many such components plugged in to do various tasks at higher levels of abstraction. If we had to verify a simple digital counter with maximum 50 lines of RTL code, yea, this would suffice. But...
