compile SystemVerilog and Verilog separately?

archive

Hi all, Happy New Year! I always use ncvlog –sv –f file_list to compile the SystemVerilog file in file_list. But sometimes, my RTL code is Verilog2001 compatible and my TB code is SystemVerilog compatible. Question is: Can I compile SystemVerilog and Verilog separately? Best regards, Davy

  • Hi Davy.

    You could use two ncvlog commands, one for the RTL files and one for the SV files.
    If for some reason you must compile everything in one command, then there is a useful trick that you can do.
    The SV LRM defines two pragmas to control the SV parser - one pragma turns off the SV keywords and the other turns them back on.
    If you put these pragmas into two files, you can import them in your file_list file surrounding the RTL (non-SV) files.

    // keywords_2001.v
    ‘begin_keywords "1364-2001"

    // end_keywords.v
    ‘end_keywords

    // file_list
    // starts in SV mode
    keywords_2001.v
      // now in v2001 (no SV keywords)
      my_rtl_dut.v
    end_keywords.v
      // now back to SV mode
      my_testbench.sv

    Compile with:
        ncvlog -sv -f file_list
