    Hi Vivek.

    Have a look in the ICC User's Guide (`ncroot`/doc/iccug/iccug.pdf) at the chapter "Generating Coverage Data".
    Specifically the -covfile option to ncelab. You start to need to use a coverage control file, which would contain something like:
    // cov_options.ccf
    select_coverage -be -module *
    deselect_coverage -be -module fred
    deselect_coverage -be -instance top.jim.dummy
    // end of file

    This example would enable block and expression coverage in every module except "fred", and instance "top.jim.dummy".
    You can get quite creative with this is you need to, and you really should read the user guide to get an understanding of what you're doing with these commands :-)

    If you're using 3-step compilation (ncvlog;ncelab;ncsim) then this .ccf file is used like "ncelab -cov58 -covfile cov_options.ccf".
    If you're using single step (ncverilog or irun) then use "irun -cov58 -covfile cov_options.ccf".
    In fact, use irun, it's brilliant because it can sort out all your C, VHDL, Verilog etc files from one command line!
