code coverage

liorr

Hi,

 I am using cadence iccr ver 6.20.

I want to watch code coverage of different tests for the same dut, but to combine the results together. (for example : i want to see if a certain fsm reached a certain state in all of the tests)

when i use the command "iccr -test 'test_*' -gui" I can see only one test at a time. Is there a way to combine the results?

 Thank You,

Lior

  • - boot up iccr in shell mode.

    - use load_test to load all your tests

    - use union to merge the coverage data of all these tests 

     

  • Once you are in the iccr shell, 

    1. Merge all the test files as follows;

    merge -code <path>/test_name* -output <test_grp_name>

    2.Then load this test merged test as follows:

    load_test <path>/test_grp_name

    3. Then view the output results of the merged test by typing "view"

     

  • Hi,

    I am testing a block written in VHDL and I have two behavioural models and I have tests for both these models. I notice that when i try to merge the tests from both the BHVs, some conditions are not hit but individual tests hit those conditions. I was wondering there is any way to merge the test files correctly or in any particular order. I do not get any error while I try to merge, except that the DUT is not specified. I use the following steps to merge and view the code coverage:

    Any suggestions/solutions would be very helpful.

    Thanks
