SANTA CLARA, Calif. & MAYNARD, Mass.--(Business Wire)--
Agilent Technologies Inc. (NYSE:A) and Signal Integrity Software, Inc. (SiSoft)
today announced guidelines that enable system designers to use advanced jitter
and broadband analog capabilities when modeling high-speed serial devices. 

The new modeling guidelines are based on proposed enhancements to the IBIS
Algorithmic Modeling Interface (116-118 and 123.5), which are expected to be
included in the specification`s next version. Both SiSoft and Agilent support
the modeling techniques in the new guidelines in advance of full

These techniques can be used to more accurately model the behavior of
multi-gigabit serial links and are already supported in the current release of
SiSoft`s Quantum Channel Designer and Agilent`s Advanced Design System
simulation environments. Tools for building IBIS-AMI models using these
techniques are included in the current release of SiSoft`s IBIS-AMI Software
Development Kit and Agilent`s SystemVue AMI Modeling Kit. 

Until now, IBIS-AMI models used to design and optimize high-speed serial links
have lacked comprehensive jitter-modeling parameters and were limited to simple,
first-order models of transmitter output drivers and receiver input-termination
behavior. Including better parameters and more advanced modeling techniques in
IBIS was first proposed in 2010, and the necessary extensions are expected to be
approved in 2013. The new guidelines from SiSoft and Agilent enable users to
create models that include techniques the two companies developed together to
support design projects for mutual semiconductor and systems design customers. 

"We appreciated the opportunity to work with Agilent and our mutual customers to
move IBIS modeling capabilities forward," said Todd Westerhoff, vice president
of software products at SiSoft. "SiSoft collaborates with customers and
suppliers to solve tough design problems. In this case, we not only addressed a
critical customer problem, but were able to validate proposed enhancements to
IBIS with another EDA vendor as well." 

"When EDA vendors collaborate, customers win," said Colin Warwick, product
manager for high-speed digital design at Agilent EEsof EDA. "By working together
we not only have a timely solution, but also the impetus to move this important
industry standard forward." 

Agilent and SiSoft worked with semiconductor suppliers to upgrade their models
using the new guidelines and tested the models for portability and consistency
of results. An illustration of the excellent correlation achieved between the
simulators is available at 

The two companies are also working with the IBIS Open Forum to incorporate the
new techniques into a future version of the IBIS specification. Doing so will
further increase the accuracy, interoperability and portability of IBIS-AMI

Both SiSoft and Agilent will be at DesignCon in the Santa Clara Convention
Center (Booths 100 and 201, respectively), Jan. 28-31. SiSoft will be showing
how it collaborates with customers and suppliers to solve the world`s toughest
high-speed design problems. Agilent will be showing high-speed digital solutions
that help engineers to design, simulate, analyze, debug and ensure compliant
designs while cutting through the challenges of gigabit digital designs.
