Testbenches

A testbench is a simulation environment used to verify that a digital circuit or system works correctly before it's built physically. It acts like a controlled testing setup, providing specific inputs and observing the outputs to ensure the design functions as intended. Think of it as a virtual testing lab for electronic components, allowing engineers to identify and fix issues early, saving time and resources. Testbenches are essential in digital design to validate complex logic, timing, and performance, ensuring reliability before manufacturing.
