ISSUE : Cumulative coverage issue in IMC

mahee424

Hi,

      I've about 400 test cases to merge all the individual coverage data bases to one output file with use of IMC. I've found the following error during merging process;

merge mipi_base_test*/scope/mipi_base_test -out final -metrics all -initial_model union_all -message 1
merge: too many arguments
merge: usage: merge [-AeEpqxX3] [-L lab [-L lab [-L lab]]] file1 file2 file3
merge aborted

even i tried giving all the individual test names but still giving the above error.

Can any one suggest me to merge all the 400 test cases?(for my case).

regards,

mahee

  • What tool version are you using? If you run "imc -batch", it should report something like:

    IMC(64): 14.20-s007: (c) Copyright 1995-2016 Cadence Design Systems Inc - Coverage engine version: 14.20-s007

    let us know that information.

    The error you're reporting is not from IMC, it's from a Linux script "/usr/bin/merge" so I think you have a scripting problem at your end (or you're using some very old prototype version of IMC that didn't have the merge command, but that seems very unlikely).
