[IBIS-Users] RE: [IBIS] Problem with IBISgeneration.

Hello, Vivek,

1) Check that your transistor model library includes the model called from
your circuit netlist. Note that model equations are often implemented
differently in different SPICE simulators, so that as a general rule model
libraries are not portable across simulation tools (different parameter
values and/or different parameter names).

2) Check to be sure you are running s2ibis2_fix (downloaded both
s2ibis2.tar.Z and s2ibis2_fix.tar.Z from the IBIS web site).

Subject: [IBIS] Problem with IBISgeneration.

Hi,

  I am new to IBIS and therefore my questions are very basic ones.

  I have downloaded the s2Ibis2 converter from the site and i tried to run
the
converter on the examples from the same site.

  I modified the command file for the spectre as well as the hspice
simulator.

  Now, if i try to run the converter on spectre, i get an error message like
:

  Error found by spectre during circuit read-in.
    stdin: minva is an instance of an undefined model pfet.
    stdin: minvb is an instance of an undefined model nfet.
    stdin: mx33 is an instance of an undefined model pfet.
    stdin: mx24 is an instance of an undefined model pfet.
    stdin: mx25 is an instance of an undefined model pfet.
    stdin: mx27 is an instance of an undefined model pfet.
    stdin: mx26 is an instance of an undefined model pfet.
    stdin: mx32 is an instance of an undefined model pfet.
    stdin: mx31 is an instance of an undefined model pfet.
    stdin: mx30 is an instance of an undefined model pfet.
    stdin: mx29 is an instance of an undefined model pfet.

 The spectre model file is the same as provided on the site.

 The circuit is tristate.sp from the ../s2ibis2/examples/ex2 extracted from
the
site.

  I also tried the example with hspice and this this too gives an error.

 Can anybody help me solve this error ?

Thx,
Vivek
