When moving to a modern constrained-random verification methodology, managing how your testbench executes and measuring its success are critical to a project’s success. Without structure, tests can wander aimlessly; without measurement, you never know when you are truly done. Here is a breakdown of how to structure your simulation phases, leverage functional coverage, and evaluate […]

To thoroughly verify a complex design, you cannot rely on ad-hoc connections and tangled code. A modern verification environment requires a structured, well-planned architecture. The fundamental purpose of any testbench is to determine the correctness of the Design Under Test (DUT). Regardless of the specific design, every testbench must accomplish five basic functions: generate stimulus,

As hardware designs grow increasingly complex, verifying that a design accurately represents its specification becomes a massive challenge. Choosing the right testing strategy is essential for finding bugs efficiently and hitting your coverage goals. Two primary approaches dominate the verification field: traditional directed testing and modern constrained-random stimulus. Here is a breakdown of how they

Imagine you are given the job of building a house. Do you start by picking out paint colors or choosing bathroom fixtures? Of course not! You first need to consider how the owners will use the space and what their budget is so you can decide what type of house to build. The same logic
