CODE COVERAGE 12 Code Coverage -Basics §Coverage models are based on the (HDL) code §Generic models –fit (almost) any programming language –Used in both software development and hardware design §Coverage models are syntactic –Model definition is based on syntax and structure of the code –Implicit implementation-specific coverage models 13
9 2 1 Code coverage The easiest way to measure verification progress is with code coverage Here you are measuring how many lines of code have been executed (line coverage) which paths through the code and expressions have been executed (path coverage) which single-bit variables have had the values 0 or 1 (toggle
–Most functional requirements can’t easily be mapped into lines of code! §Functional coverage modelsare designed to assure that various aspects of the functionality of the design are verified properly they link the requirements/specification with the implementation §Functional coverage models are specific to a given design or family of

• Model Element Coverage • Requirement Coverage • Code Coverage In this tutorial we would like to give you an impression of the Rhapsody Testing Environment which goes beyond current embedded systems testing technologies It ensures that the system can be continuously tested throughout the design process The
What is a functional coverage model?
A functional coverage model allows the automatic tracking of the progress of the verification implementation. This model also enables a coverage-driven verification strategy that can leverage automation in the verification environment to minimize the amount of code necessary to implement all of the requirements of the functional verification.
What is code coverage in functional verification?
Coverage is a metric to assess the progress of functional verification activity. This plays a major role to get a clear picture on how well the design has been verified and also to identify the uncovered areas in verification. Code coverage and functional coverage are the two types of coverage methods used in functional verification.
Does the code coverage reporting functionality provided by the task work?
At present, the code coverage reporting functionality provided by this task is limited and it does not merge coverage data. If you provide multiple files as input to the task, only the first match is considered. If you use multiple publish code coverage tasks in the pipeline, the summary and report is shown for the last task.
What are IBM function-authorization feature codes?
