Generating an ICCR output report with cumulative coverage metrics

danlarkin

Hi,

I'm using ICCR (6.20-s004)  and I'm trying to generate an output text or html report with cumulative block and expression coverage listed. When I use report_tabular_summary -instance <module_name>... or report_html -instance <module_name>... I seem to be getting the coverage metrics for each individual module in the hierarchy thats specified. This is almost what I want, but I'd like to be able to see the cumulative coverage details at each level of the hierarchy too.

Now I tried report_summary -module <module_name>  and that gives me the the cumulative coverage figures that I want, but this type of report doesn't list the submodules (short of generating -module reports for all the blocks thats of interest).

Am I missing something in the documentation? (and I'd really rather not use the gui)

 

  •  Hi Dan,

     I believe what you are looking for can be found in the report_summary output.  Try using "report_summary -instance -be *..."

     The resultant output will be similar to the following snippet:

    cpu_test
    --------------------------------------------------
    B:  100% (4/4)           BC:   75% (92/122)

    The left hand B/E rows indicate the block and expression cov stats for the specified instance.  The BC/EC on the right of each line provide the cumulative block/expression status for the specific instance and all instances found hierarchically below that instance.  In the example above, the hierarchy of the design is as follows:

    cpu_test

    cgen

    cpu1

    ac

    ir

    pc

    alu1

    u3

    smx

    mem1

    cntl

    cpu2

    ac

    ir

    pc

    alu1

    u3

    smx

    mem1

    cntl

    Note the cumulative coverage values for each instance and the hierarchy found below.

    Hope that helps.
