Coverage using "iccr"

archive

Hi Friends,
  I am doing Coverage  in the Master Monitor for my uVC. I have created a Covergroup which contains 3 coverpoints for Covering Address,Data and Direction. I am using "iccr" for viewing Functional Coverage results but WHen i look in to the DATA-ORIENTED coverage  I am getting two Instances of of single Coverpoints,say for ex: trans_addr is the coverpoint
    1) top.urm_test_top.sve.env.master_agent.monitor.cov_trans.trans_addr   
     2)top.xyz_master_monitor::cov_trans.trans_addr
I Cant understand why the 2nd instance is being Created though there is No Instance or Handle from top to Master monitor !!

And also I can see a Message as "Displaying 13 coverage points". Here I cant Understand y 13 coverpoints are created though i have specified 3 coverpoints in the covergroup !!
 
Regards,
Ramesh Pal

  • In the data-oriented functional coverage reports you will see more than one report for your covergroup. One reports the combined coverage for every instance of the covergroup. There will also be additional reports for each instance of the covergroup.

    covergroup grp; ... endgroup

    grp seq1 = new();
    grp seq2 = new();

    Here you'll see 3 examples in the iccr report. One will be the combined coverage for all instances of grp created in the test. Then there will be 2 additional reports showing the coverage in seq1 and the coverage in seq2.

    I don't know where you see the message "13 coverage points", I think that you'll need to give us more information. But remember that each coverpoint will often have more than one bin, so typically there will be more "coverage points" that you need to hit than there will be SystemVerilog "coverpoints" in the source.
