Coverage error

sriganeshd

Hi  all,

          I am getting this warning in while generating the coverage report, can you help me to clear this warning?

ncsim: *W,COVOPM: Coverage configuration file command "set_covergroup -optimize_model" can be specified to improve the performance and scalability of coverage model containing SV covergroups. It may be noted that subsequent merging of a coverage database saved with this command and a coverage database saved without this command is not allowed.

  • The warning just means that you're using a non-default option, and if you try to merge tests that still use the default, with tests that use this setting, it won't work.

    So long as you use the option consistently for all tests, you can ignore or suppress the warning (xrun -nowarn COVOPM)
