SiSoft and Physware Demonstrate Joint Solution for Serial Link Design and Analysis


SiSoft and Physware to Demonstrate Joint Solution for Serial Link Design and Analysis at DesignCon 2009

Santa Clara, CA – February 2, 2009 - Signal Integrity Software, Inc. (SiSoft™) and Physware, Inc. (Physware™) announced they will demonstrate how Physware’s PhysWAVE™ and SiSoft’s Quantum Channel Designer™ can be used together in a multi-gigabit serial link design and analysis flow. The two companies will demonstrate a flow that lets designers quickly evaluate tradeoffs in their passive channel design against different SerDes IP equalization strategies.

In the demonstration to be shown at DesignCon 2009, PhysWAVE was used to create parameterized models for different via design alternatives. PhysWAVE swept-parameter analysis was used to automatically create models for 120 possible combinations of differential via entry and exit layers, antipad and backdrilling options. Quantum Channel Designer reads in 120 S-parameter models and adds them to its library within seconds, then allows designers to interactively evaluate the performance of different via options and SerDes equalization configurations on overall link behavior.

“Effective high speed serial link design requires evaluation of different channel design alternatives and their impact on link performance” noted Feng Ling, Physware’s VP of Engineering. “Via design is an area of intense study because there is always a tradeoff between minimizing the discontinuity a via imposes on the signal and other considerations, such as maintaining copper area in the planes under complex IC’s. PhysWAVE’s high speed, accurate performance and inherent scalability make it ideally suited to rapidly and automatically creating a large collection of via models that can be evaluated in the context of the overall channel using a tool that can efficiently work with large data sets, such as Quantum Channel Designer.”, he added.

“In the past, designers have been unable to run enough simulation to validate their combined channel / SerDes design”, said Barry Katz, President and CTO of SiSoft. “As a result, most designers have had to focus on their passive channel design alone. Quantum Channel Designer uses high performance IBIS-AMI models that allow designers to analyze the combined behavior of their channel and SerDes IP. Designers can finally run enough simulation to make tradeoffs between their passive channel design and SerDes IP configuration. Quantum Channel Designer can evaluate hundreds of different channel design configurations (via design, connector pinout, package model, PCB trace and SerDes IP setting) within minutes, extracting key design metrics like insertion loss, eye height and projected Bit-Error-Rate (BER). Using Quantum Channel Designer together with a high performance, high accuracy 3-D full-wave field solver such as PhysWAVE gives designers a level of performance and flexibility they have never had before.”

SiSoft and Physware representatives will be demonstrating Quantum Channel Designer™ and PhysWAVE™ on the show floor at DesignCon in Santa Clara. Exhibition hours are from 12:30PM to 6:30PM on both Tuesday and Wednesday, February 3-4.

About SiSoft™
SiSoft™ is the leading provider of integrated signal integrity and timing solutions for high-speed digital system design. SiSoft's latest product, Quantum Channel Designer™ (QCD), is a dedicated, system-level design and analysis environment for serial links up to 20 Gbps. QCD incorporates the latest frequency-domain, time-domain and statistical techniques to simulate the combined behavior of the passive channel and SerDes IP. Designers capture designs graphically, and then experiment with different physical layout and equalization strategies to predict how design tradeoffs affect operating margins and link Bit Error Rate (BER). Standards-based (IBIS-AMI) SerDes IP models provide the accuracy and performance required to meet the needs of serial link design.

SiSoft’s Quantum-SI™ products allow users to rapidly determine interface operating margins and achieve High-Speed Timing Closure™, providing unprecedented accuracy in predicting system-level noise and timing margins. Quantum-SI Interface Analysis Kits are pre-configured analysis setups for popular interface standards, such as DDR2 and DDR3, which encapsulate both interface architectures and design requirements to accelerate the high-speed design process.

SiSoft’s consulting services organization uses Quantum Channel Designer and Quantum-SI tools to provide advanced high-speed consulting services including IBIS model development, package design/analysis and system-level interconnect analysis -- ensuring that SiSoft’s signal integrity tools remain at the forefront of high-speed design.
