...and a simple search will find a few out there already in the
standard flavours.

Verilog-a example:
http://www.eda.org/verilog-ams/models/opamp.va

(remembering that most of the main Spice variants these days support
straight Verilog-a too [which, in my humble opinion is fantastic]).

There is a nice paper on a vhdl-ams version on the IEEExplore site too
(Google finds it OK with: vhdl-ams opamp)

Regards,
Richard

Jebasingh,

Even though the previous answers are correct for
normal IBIS models, you could consider using the
Verilog-AMS or VHDL-AMS language extensions in
IBIS for modeling your Op-Amp.

I can't think of any reasonable way to model an op-amp in IBIS. IBIS
supports bi-stable buffers and non-linear passive loads, but not linear
amplifiers.

Hi all,
Can any one please tell me how to convert the SPICE model to IBIS model
for OPAMP?

Thanks in advance
