Merging code coverage from two different test benches

Hi

I am facing issue while merging code coverage from two different test benches.

Here is my testbench and tools :

One test bench(A) is written in SV and other test bench(B) is written in Verilog.

I am using IUS62 to run test cases and ICCR to merge coverage and generate report.

Both testbenches are pointing to same RTL core but the hierarchy is different.

I ran test case in both the environment and tried to merge code coverage report.

Here, ICCR is not loading the test because different model file (<checksum>.model) are generated.

I would like to know which are the points I should take care while running the test case and while merging coverage.

Please let me know your inputs.

Thanks & Regards,

Nilesh Goswami

    Thanks  Mickey, Fepcine and Cadence Team for their wonderful support.

    Here is the way it get resolved :

    Till now we are compiling and elaborating "RTL files" in respected Envs independently using "irun" in one and "nc commands" in other. With different commands this creates merging issue in tool even with same arguments and model number file.

    As a solution,now we are not compiling RTL files (design files) again in both Env, instead, we are re-using already compiled worklib of design files of one Env. i.e. `fmr_worklib` located @ .../data/compiled/rtl
    By doing so, we are making sure to have same elaborated data base in use in both Envs and thus merging problem is eliminated in spite of different commands, "irun" and "nc commands".

    Previously, we had also got solution by converting "nc commands" to "irun" too. But, the above change is minor and quickly accepted by Team.

     

    Kind Regards,
