Constraint Random Verification with Python and Cocotb

Testing digital hardware has never been an easy job, and it won’t get easier any time soon. But that doesn’t mean writing test code can’t be enjoyable and productive! Cocotb, an approach to use Python as verification language, is bringing the joy back to verification. It allows developers to start with small, directed testbenches, and evolve them into more thorough constraint-random tests. Much has been said in the past about directed tests and system-level tests with cocotb. In this talk, we’ll explore how to design more advanced constraint random testbenches. We’ll look the different approaches for constraint random verification in cocotb and how you can turbocharge your next cocotb test problem!
