RE: low budget IBIS tools

Ted, regarding the IBIS to SPICE conversion in the AMPredictor tool;
is the SPICE behavioral model output a file which can also be read by tools
like HSPICE, PSPICE? How do you verify the accuracy of the IBIS models and
also have you verified if any critical information has been lost in the
conversion process?
Does anyone else out there know of any other tools which are available for
sale which convert IBIS files to HSPICE or PSPICE formats?
Thanks,

Hi Rick,

AMP Inc. offers a signal integrity tool called the AMPredictor Signal
Integrity Analyzer. ($8,500 for a single license, $5,000 a piece if
you purchase 3 licenses.) It is a Spice-based pre-layout tool that
includes a complete Spice engine, a 2-D field solver that generates
coupled-lossy transmission line models, connector noise analyzer, and
an IBIS-to-AMPSPICE converter. The software can convert an IBIS data
file to a SPICE-format analog behavior model. It then can be used
with the AMPSPICE engine to perform Spice-based critical net analysis.

There is more information on the website.

Subject: low budget IBIS tools

are there such a thing? I'm doing a 40 Mhz microprocessor design
which
looks like it has some potential problems with the bus layout. I'd
rather not spend the 5 to 50K for modelling tools if I can help it.
 Are
there any lower cost IBIS to spice convertors out there? And is the
conversion accurate (i.e., do you lose information in the conversion
from IBIS to spice), or should I be looking for native-mode tools?

Thanks in advance.
