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,...

Code Coverage can be roughly divided into statement coverage and branch coverage. Statement coverage provides information on which statements inside the VHDL or Verilog code were executed (covered) during simulation and how many times. Branch Coverage examines the execution of conditional statements (e....
只对指定层次的模块,以及该层次下的模块,不统计coverage。level_number,表示从该层次模块,向下不统计coverage的层次。0表示不统计所有,1表示只不统计当前层,2表示不统计当前层和下一层,之后依次类推。 3.3 +module module_name | entity_name VCS compiles all instances of the specified Verilog module or VHDL...

keil的code coverage输出到txt或者html中 KEIL中自带了code coverage功能,我们在进行软件仿真的时候,可以打开view-analysis windows-codecoverage 界面,我们就可以看到程序的覆盖率信息, 这个时候我们会看到窗口会出现覆盖率信息, 有的时候我们需要将覆盖率信息导出到txt文件中,这个时候我们需要打开common界面 我们可以在图...
The "vsim" command is called using the host machine shell environment to run "runme_verilog.do" file. You can use your own run.do file in this project. The code below shows the .do file used in this app note. alib work adel -all alog -coverage sb -coverage_options count \ src/...
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...
