Verification of a design usually follows the flow synopsis below.
After the preliminary design specification is completed, the first verification phase is started Verification planning.
Verification planning consists, following main tasks.
1) Feature extraction from design specification.
2) Listing out Testcases.
3) Verification Environment Architecture plan.
Extract all the features of the DUT from the design specification.
Mainly the features are configuration, Interface protocol, data processing protocol and status communication.
Categorizing all this features according to where these features are verified.
What are the features covered by random stimulus generation?
What are the features verifiable by writing separate test cases?
What features assertions can catch?
What features the coverage module contains?
Verification Environment Architecture Plan:
Verification plan contains the structure of the Verification environment. Based on the project requirements, following points are considered while Architecture is built.
Reusability, Is it a verification IP. What blocks the verification language can support.
Controllability of the stimulus generation etc.
Next phase is to build the Verification environment.
Final phase is to verify the DUT using the environment built.
