    IMC Merging Issue of different test case of the same DUT. Reply

    Dear All,

    I'm trying to merge the coverage report of different test case of the same DUT but im getting an error saying.

     

    Block coverage not merged - Checksum differs. Data is projected in to the target model.

     

    The steps used for generating the coverage are:

     

    1. Used the -coverage all option in the irun command "irun -coverage all"

     

    2. Generated coverage for each test case in test_xxx folder.

     

    3. Used the batch method to merge the each test case coverage into single coverage in coverage_log folder.

     

     Please refer the below error message and suggest me to slove the issue.

     

    [bin]$ imc -batch merge_ncsim.cmd

     

    imc: 11.10-p001: (c) Copyright 1995-2011 Cadence Design Systems, Inc.

    Starting batch mode

     

    imc> merge test_001/cov_work/scope/test/ test_002/cov_work/scope/test/ test_003/cov_work/scope/test/ test_004/cov_work/scope/test/ test_005/cov_work/scope/test/ test_006/cov_work/scope/test/ test_007/cov_work/scope/test/ test_008/cov_work/scope/test/ test_009/cov_work/scope/test/ test_010/cov_work/scope/test/ test_011/cov_work/scope/test/ test_012/cov_work/scope/test/ test_013/cov_work/scope/test/ test_014/cov_work/scope/test/ test_015/cov_work/scope/test/ test_016/cov_work/scope/test/ test_017/cov_work/scope/test/ test_018/cov_work/scope/test/ -out all -overwrite -metrics all

     

    imc: *W,MGOPOW: The merge output directory cov_work/scope/all will be overwritten.
