Verification quality improvement – Test bench

Test bench quality overhaul involves three primary activities cleaning, trimming and refactoring.

First step of quality overhaul is cleaning and trimming. Typically verification solutions with the quality problems would have developped weeds. Weeds are redundant and useless growth in the code. This is a distraction. In order to focus on the right problems first step is to trim it and clean it.

Trim the verification plans, regression lists consisting of test variants and seeds per test. Trim the tests. Trim test benches.  Be ruthless clean, trim and cut it down. Trim in all aspects of the functional verification.
