NEWARK, Calif. –– March 22, 2006 – Prolific Inc. today announced that VeriSilicon Holdings Co., Ltd. (VeriSilicon), a leading ASIC design foundry, has entered a multi-year agreement to license Prolific's ProGenesis® software, which accelerates the creation of standard cell libraries. VeriSilicon will use ProGenesis to do layout architectural exploration in producing multiple libraries for its Standard Design Platforms (SDP), target them to multiple fabrication processes, and produce updates as design rules change for those processes.

“With a growing list of more than 500 customers worldwide using our SDPs, ProGenesis gives us powerful capabilities for creating and customizing libraries,” said Dr. Wayne Dai, president and CEO of VeriSilicon. “ProGenesis is helping our SDP take DFM, low power, low leakage, and small footprints into consideration as we explore opportunities to cover more technology processes and nodes. We have found through experience that Prolific shares our passion for outstanding design, and for providing attentive customer service.”

“We are pleased that ProGenesis is helping VeriSilicon provide state-of-the-art SDP,” said Dr. Paul de Dood, president and CEO of Prolific, Inc. “ProGenesis is the only tool capable of satisfying all design rules and other requirements of advanced technologies.”

Complete Standard-Cell Library Control

ProGenesis is the automated cell library creation tool that reduces development time from man-weeks to days and adapts to changes in design requirements or rules. Used by independent device manufacturers (IDMs) and fabless semiconductor firms around the globe, ProGenesis supports design for manufacture (DFM) practices and design rules down to emerging 45 nm processes. ProGenesis produces standard cells as small or smaller than hand-drawn results, and can easily update cells for changing processes.
