收集和分析code coverage指标的目的是识别RTL代码中在当前的验证环境中未被执行的部分。 从项目的角度来看,通常最好等到RTL实现接近完成的时候才开始收集和分析code coverage,否则,可能会因为RTL代码的修改,浪费大量没有意义的时间。 在开始收集code coverage之前,先运行一些仿真以解决code coverage流程中的其他问题。

Practical code coverage for Verilog 来自 IEEEXplore 喜欢 0 阅读量: 31 作者:TH Wang,C Guan Tan 摘要: The ability to detect sections of code that have not been executed in a program or design has always been desired by hardware designers, since unexecuted code is clearly untested code. ...

Types of RTL code coverage There are several types of RTL (register transfer level) code coverage that can be used in SystemVerilog verification, including: Statement coverage: This measures the percentage of code statements that have been executed during the simulation. ...

Code coverage is a measure of how well the RTL code has been exercised by the test bench. Code coverage is automatically extracted by the simulator when enabled. Vivado Simulator currently supports four types of code coverage, that is, line, branch, cond
The best thing though would be for you to read the ICC tutorial which will give you a good introduction to doing coverage in IUS.You can find that under "cdsdoc", or if you prefer to use PDF docs (like me) then this will get you there:[i]acroread `ncroot`/doc/incovtut/incovtut...
