    merging issues in functional coverage Reply

     Dear Sir/Madam

    I am having problems in merging the databases generated for functional coverage. Individually tests show that the individual cvergroups/coverpoins show higher values, but when merged these values fall. also by experimentation i foudn that these happen to bethe values accumulated for the last test that gets merged.

    tool; IUS8.2, ICC

    commands in irun:

      @irun -coverage U -covoverwrite -covdut tb_top  -covfile ./cov_spec -covtest $(TESTCASENAME) -covworkdir ../simulation/coverage

    and/or

    @irun -coverage all -covoverwrite -covdut tb_top  -covfile ./cov_spec -covtest $(TESTCASENAME) -covworkdir ../simulation/coverage

    commands in icc:

    set_dut_modules DUT_TOP
    merge ./coverage/design/test1 ./coverage/design/test2 -output all_tests
    load_test ./coverage/design/all_tests
    report_html  * > ./coverage/report.html
    view_graphics

     Could you guide me in this regard
