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

 

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
