using nport in Verilog-AMS

TobiasM

Hi everybody,

I want to use a nport in Verilog-A/Verilog-AMS. The implementation has been done like this:
nport #(.file("/my_folder/my_device.sparam"), .interp("spline"), .thermalnoise("no"), .usewindow("yes")) N0 (BiasN, AVSS, BiasN_cm, AVSS, BiasP, AVSS, CBiasN, AVSS);
But when I try to simulate, there's this error that the file can't be found.
ERROR (CMI-2011): Unable to open S-parameter file `"/my_folder/my_device.sparam"'.

When I copy the path and try to open the file with emacs there's no error. So could someone tell me, where's my error in implementation or usage?

Thanks a lot,
Tobias

  • Thanks for your advice. I now tried everything relating the way how to define the path. absolute (starting with /), relative (with ./) and, as the file is in a subdir of my home directory, with a ~/...../ .
    the solution with the ~/ is correctly substituted with my home path, as the error message points to the correct file.

    in my opinion, it is strange that the errormessage quotes the path twice, once with ` and then directly after the first quoting with " and closes then the " quote and the the '.

    Has anybody already implemented the nport in verliog-a or verilog-ams? could someone post a code snippet for example?

    kind regards,
    Tobias
