covergroup的覆盖率通过get_coverage()等方法获取,vcs的覆盖率需要通过urg、DVE等工具从数据库文件中生成报告查看。 covergroup收集覆盖率回带来较大的性能开销,需要根据需求选择性收集。vcs收集代码覆盖率的开销较小。 总的来说, covergroup侧重功能验证的全面性,vcs侧重代码实现的完整
SystemVerilog Randomization and Functional Coverage
SystemVerilog Randomization and Functional Coverage
For an example that uses the HDL Verifier Assertion block, see Generate Native SystemVerilog Assertions from Simulink. In SystemVerilog, every model verification block and verify statement is mapped to an assertion and a coverage point. You can adjust coverage goals, filter specific ...
Using SystemVerilog Assertions for Functional Coverage Mark Litterick, Verilab mark.litterick@verilab.com ABSTRACT SystemVerilog Assertions (SVA) can be used to implement relatively complex functional coverage models under appropriate circumstances. This paper explores the issues and implementation of ...
A new feature in 8.2 is the monitor port. A monitor port is like an in method port that makes monitoring embedded software very easy. Using monitor ports engineers can learn a lot about what is actually happening in the software and passively collect functional coverage, but this sounds like...
Design and Functional Verification of A SPI Master Slave Core Using System VeilogSPIWishbonecoverageSynchronous serial interfaces are widely used to provide economical board level interfaces between different devices such as microcontrollers, DACs ADCs and other. Many IC manufacturers produce components that...

UVM testbench with DPI integration, Assertions and Functional Coverage In this project a complete verification testbench architecture for a result character conversion chip is constructed. The testcase used for verification are the randomly generated input transactions for the DUT. ...
Concepts such as, coverage, constrained random generation, assertion checking, simulation time and interacting with a design under test are absent from modelling languages targeting other domains. In addition, many of these properties are verification concerns that cut across the structure and behaviour ...
