SystemVerilog DPI in NCSim?

archive

Hi all, Because it will take some time waiting download IUS583, I tried to use SystemVerilog DPI (mostly imported functions). I heard that Synopsys can simply include C file in file list with SystemVerilog file and run simulation. But Cadence NC seems need C code compile and link to a lib. I have read the NCsim document and find a switch "-sv_lib". But I cannot find a simple example. Is there any step by step tutorial about how to compile, link and run SystemVerilog DPI C file in NCsim? Best regards, Davy

  • Hi Davy.

    Cadence does not modify the gcc tool, so all the options I showed previously are standard gcc ones.
    "gcc --help" will giv you lots of detail.

    The options I used are:
    "-fpic" : create relocatable code
    "-shared" : create a shared lib rather than a statically linked binary
    "-o libdpi.so" : sets the name of the output file

    One other flag you may need is "-m32", which sets the compiled code for 32 bit mode if you compile on a 64 bit machine.

    Regarding the dpi_example.tar.gz, the version I uploaded is OK, but when I download it, the file is corrupted. I'll try uploading it again here, and if that fails, feel free to email me directly and I'll send it to you by email.

    Regards,
    Steve.
