I am checking the code coverage for one of my Module's testbench, but the expression coverage is appearing as "n/a" , why is that so ? there are if-else & assignments in the RTL... how do I enable it ?

  • Hello Stephan,

                I am using the following options in my run command :

    /////////////////////////////////////////////////////////////////////////////////////////////////////////////////

    "set compileOptionsTb            = -nocopyright -errormax 1 -linedebug \
                                      -messages \
                                      -COVERAGE all -covdut <dut-name> -covfile <naME.covfile>"

    //////////////////////////////////////////////////////////////////////////////////////////////////////////////

    And, my covfile is as follows :

    select_coverage -all
    set_expr_scoring -all
    set_assign_scoring
    set_libcell_scoring
    set_fsm_scoring -hold_transition
    set_fsm_arc_scoring -on
    set_branch_scoring
    set_explicit_block_scoring -off -case

    set_ignore_library_name

    /////////////////////////////////////////////////////////////////////////////

    in spite of that, even though I have expressions in my dut, I cannot see them in the IMC.

    Thanks in advance.

    Regards,

    Saraswati
