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
