Figure 1: Example Functional Coverage Syntax Each covergroup contains options for configuration which allows customization. The example shown in Figure 1 uses options which determine the number of bins that are created for the pwdata signal and whether the covergroup is static across all instances or ...
Parameterized IP also continues to expand in size which compounds verification complexity. Previous DVCon papers have addressed issues related to using parameters with UVM [1] and employing code, functional and assertion coverage with parameterized IP [2...

这段时间UVM的基础差不多了,歇口气,回过头来继续完成之前的systemverilog工程。 在(一)里面只用到了一个output_monitor,并且generator到driver也只做了一次数据的测试。 现在的改进版结构是下面这样的: 主要是添加了input_monitor和对应的两个mailbox,同时对scoreboard做了修改,通过在scoreboard里面加入transaction类型的联...

结果发现,Angular CLI默认禁用代码覆盖率。您需要使用ng test --code-coverage启动测试才能使其正常工作。 您可以通过在angular.json文件的test任务中添加"codeCoverage": true来始终启用它: { "$schema": "./node_modules/@angular/cli/lib/config/schema.json", ...
functional coverage helps in ensuring that the expected values are covered, and the unexpected ones are uncovered, as illustrated in Figure 2. Figure 2(a) shows that the tolerance with the modeled PLL vcontrol increased or decreased by 2% (0.02), which means the values that are greater than...

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. ...
(which require no prior knowledge of formal or assertion-based verification), are becoming more common by the day. In this case, Mentor’s formal-based CoverCheck is clearly the right tool for this specific verificat...
