SiSoft Collaborates with Inphi to Extend IBIS-AMI for Repeater Modeling

SANTA CLARA, Calif. - (BUSINESS WIRE) - Signal Integrity Software, Inc. (SiSoft ) today announced the company is working with Inphi Corporation (NYSE: IPHI), a leading provider of high-speed analog semiconductor solutions, to extend the IBIS-AMI SerDes Modeling Standard to support multi-gigabit repeaters and other non-linear elements. The current IBIS 5.0 specification makes the assumption an Analog Serial Channel is both Linear and Time-Invariant (LTI), and therefore cannot accurately model nonlinear elements such as analog repeaters. New IBIS-AMI extensions developed by SiSoft and used by Inphi will allow IBIS-AMI models and EDA tools to:

Model the nonlinear behavior of high-speed analog repeaters
Model noise introduced by active (repeater) elements in the middle of a transmission path
Model any number of connected nonlinear channel elements

SiSoft has been collaborating with Inphi since early 2009 to develop advanced techniques for simulating links operating at rates of 25 Gb/s and higher. "We chose to work with SiSoft because of their demonstrated leadership in IBIS-AMI," said Norman Yeung, Vice President of Engineering at Inphi. "SiSoft's deep expertise in simulation and modeling with an exclusive focus on advanced system-level signal integrity aligns with Inphi's continued innovation in high-speed, high-signal integrity semiconductor solutions."

"Working with Inphi has been a great experience" , said Barry Katz, SiSoft's President and CTO. "At a time when most of our customers were looking at 10 Gb/s, Inphi was already working at much higher speeds with emphasis on signal integrity. Collaborating with Inphi has allowed us to develop simulation and modeling techniques that accurately represent behavior down to the picosecond level, which is critical at these very high speeds."

SiSoft will be demonstrating IBIS-AMI repeater models running in SiSoft's Quantum Channel Designer software at DesignCon, February 1-2, 2011. SiSoft will also be presenting the IBIS-AMI extensions used to model repeaters at the IBIS Summit taking place at DesignCon, February 3rd, 2011.
