nccovdut option : Can it have more than 1 option?

Pooja

Hi,

      I use ncverilog and the DUT for which am working on currently has a seperate Tx top and a seperate Rx top,

and it  does not have a common top level or rather the design team wants to keep the Tx and Rx seperate.Now I

want code coverage for Tx as well as Rx,is it possible to have 2 arguments to the nccovdut switch? Meaning

can we have +nccovdut+xyz_tx_top+xyz_rx_top in the makefile? Please let me know your thoughts as to how can  i

get code coverage of Rx and Tx wherein I have them as seperate modules and also don have the luxury to put

them together in a top level design file?

  • Hi Pooja,

    The nccovdut option only takes one module name as an argument.  If the Rx and Tx are defined as two different modules, you can have more than one nccovdut command line options, eg. +nccovdut+tx_module +nccovdut+rx_module.  If the rxtop and txtop are two instantiations of the same module and you want instance level coverage for each instantiation, you need to specify coverage with a coverage configuration file.  Take a look at the ICC documentation for specific information on how to specify coverage in a coverage configuration file.

    Please let me know if this helps.

    Best regards,

    Mickey
