ISSUE: Merging coverage databases for more than 100 testcases

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'm using below IMC version;

IMC(64): 14.10-s011: (c) Copyright 1995-2014 Cadence Design Systems Inc.

I've found the following error during merging process in BATCH MODE;
mydir> imc -batch
imc>merge mipi_base_test*/scope/mipi_base_test -out final -metrics all -initial_model union_all -message 1
imc>merge: too many arguments
imc>merge: usage: merge [-AeEpqxX3] [-L lab [-L lab [-L lab]]] file1 file2 file3
imc>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

  • The number of tests is not your problem, I can do the same command here and it works.

    % imc -batch

    imc> merge mipi_base_test*/scope/mipi_base_test -out final -metrics all -initial_model union_all -message 1

    So, I'm sure the problem is in your environment somehow. If you'd been pasting the command from an email or documentation, try typing it out manually, in case there are some hidden special characters screwing everything up.

    Please note that 14.10.011 is very old, it came out in early 2014, please consider using a newer version; the last 14.10 update was in May 2016, or you could look at using a supported version such as 15.20.
