1. What is the difference between code coverage and functional coverage? There are two types of coverage metrics commonly used in Functional Verification to measure the completeness and efficiency of verification process. 1) Code Coverage: Code coverage is a metric used to measure the degree to which the design code (HDL model) is tested by…
Functional coverage and code coverage both are contributing highly on sign off criteria for verification. Implementers have to make sure that their test plan and test environment is intelligent enough to satisfy the code/functional coverage closure. Code coverage is generated by tool with the help of the simulations generated by the test environment. So test…
Coverage is used as a metric for evaluating the progress of a verification project. Coverage metric forms an important part of measuring progress in constrained random testbenches and also provides good feedback to the quality and effectiveness of constrained random testbenches. Types of coverage metrics – Let’s understand the types of coverage more deeply Code…
Functional Coverage is very important in Test Bench Development. It always gives us confidence in covered items listed on the verification plan. Usually, the goal of a verification engineer is to ensure that the design behaves correctly in its real environment according to specifications. Defining a coverage model is very important for any test bench…
