Testbench
A testbench is a virtual environment used to verify a component or system by providing inputs, stimulating its operation, and observing outputs to determine correctness. It is commonly employed in both hardware and software contexts to validate behavior before deployment or production.
In digital electronics, a testbench is typically written in a hardware description language such as VHDL or
Common features of hardware testbenches include clock generation, reset sequencing, directed and randomized stimulus, coverage collection,
In software engineering, the term test bench (or test harness) describes a framework that runs a suite
Best practices emphasize separating stimulus generation from verification logic, minimizing hard-coded assumptions, and maintaining test readability
