Re: help with ibis

Hi,

Most of your syntax is wrong.

  You are missing a field in the above line. Below are the fields required.
  pin_name spice_node signal_name model_name

See the example in s2ibis2/examples/ex2/tristate.s2i, you need to make use of
the "->" syntax and create dummy model

    Needs to be of this format: hspice %s >%s 2>%s
        
    Extracted from the doc file:
        It has three "%s" printf conversion
        characters, one each for the spice input file, the spice output
        file and the spice message file (this last is optional), IN THAT
        ORDER. See the string variable defaultSpiceCommand in the file
        src/s2istrng.h

    Not familiar with this keyword!!

This keyword does not require a blah but if you want to use [Package model] then
you can specify a blah..

I would suggest that you read up on the /doc/s2ibis2.txt and also try
out the examples before running a translation on your design.

You should also be using the s2ibis2_fix version of the tool.

Hope this helps.
