SiSoft awarded U.S. Patent for key software technology

Maynard, MA -- January 8, 2007 - Signal Integrity Software, Inc. (SiSoft™) announced it has been awarded United States Patent 7,143,023 for key software technology in the company's Quantum-SI™ product family. Quantum-SI integrates static timing and signal integrity analysis to bring High-Speed Design Closure™ to high-speed digital designs.

The patented TransferNet™ technology used in Quantum-SI enables automated high-speed design analysis of entire interfaces once key design information has been captured. This permits interface architecture and performance requirements to be reused across multiple physical implementations of an interface. SiSoft offers interface analysis "kits" for key interface technologies (such as DDR2 and DDR3) that greatly reduce the time needed to design and analyze high-speed interfaces.

SiSoft's patented technology supports the integration of static timing and signal integrity analyses. It also enables mapping of logical to physical data allowing pre-layout interface representations to be automatically mapped to a specific design's physical implementation. This ability to automatically map between pre-layout and post-layout interface representations dramatically reduces the amount of effort needed to analyze a design after PCB routing.

"TransferNet technology is a key component in enabling interface analysis kits and easing customer design burdens", said Barry Katz, president and CTO of SiSoft. "As an example, our DDR2 analysis kit includes automatic management of on-die termination settings and allows simulation results to be derated in accordance with the JEDEC DDR2 slew-rate specification. Quantum-SI interface analysis kits let designers spend time concentrating on their design and the consequence of different design decisions, instead of setting up and running simulations. Because design requirements for technologies like DDR2 have already been captured in kit form, Quantum-SI can do the simulation setup work and analysis automatically."

SiSoft's Quantum-SI™ product family is available in configurations starting from $15,200.
