Code coverage指标无法分析功能验证的情况,但是由于Code coverage的自动化方面的优势,其仍然是验证流程中的一个非常重要的验证指标。 Code Coverage类型 Toggle Coverage Toggle Coverage用于测量register 或者wire的每个bit toggle的次数。 查看Toggle Coverage分析报告比较费力,而且价值不大,通常用于IP之间的连接检查。此外,T...

Coverage measurement also helps to avoid test entropy. As your code goes through multiple release cycles, there can be a tendency for unit tests to atrophy. As new code is added, it may not meet the same testing standards you put in place when the project was first released. Measuring code...

Back-annotation of the model with critical path information and other information obtained during synthesis. ...
. However, for maximum coverage please run test-all.sh which will run gofmt, unit tests, race detector and then all of the integration tests. All of those must pass to ensure a stable release. API Support The core part of scc which is the counting engine is exposed publicly to be ...
Code coverage exclusion caseSelvavinayak over 11 years ago Code coverage has added an "all-false" bin for Verilog case statements that do not contain a "default" clause. How to exclude a default statement in case statement in code coverage while we simulate in cadence?
