Re: gEDA-user: passing parameters to a subckt

[D T <dnt2y@xxxxxxxxx>]

    Thank you Al. Just for the record: ngspice worked; gnucap didn't.
    Details follow.

    The directions from the subckt section of the NGSPICE User Manual
    (http://ngspice.cvs.sourceforge.net/viewvc/*checkout*/ngspice/ngspice/n
    g-spice-manuals/manual.pdf?) did their job exactly as described.

    The directions from the GNUCAP's page:
    http://www.gnucap.org/dokuwiki/doku.php?id=gnucap:manual:compatibility:
    subcircuit_with_parameters

    didn't work for me. Here's the error message followed by the test code
    ran on gnucap-0.35

    Of course there is.
    Well .. not spice 3f5 but gnucap does, and I believe ngspice
    does, in the latest version.
