Celestry Introduces Cell Noise Characterization Software, Socle Selects Celestry for Sign-off

Nautilus-SI and CellXpert-CN Pair Up for Accurate Signal Integrity Sign-Off

SAN JOSE, Calif.--(BUSINESS WIRE)--April 8, 2002--Celestry Design Technologies, Inc., the leading provider of Silicon Accurate Sign-off(TM) technology for the semiconductor and electronics industry, announced today that it is shipping the first member of its cell noise characterization family of products -- CellXpert-CN(TM).

In addition, Celestry announced that Socle Technology Corp. (Hsin-Chu, Taiwan), a TSMC Design Center Alliance company, has selected CellXpert-CN for cell noise characterization and Celestry's Nautilus-SI(TM) for signal integrity sign-off by Socle's RTL2Silicon service.

CellXpert-CN eliminates cell noise library characterization iterations by using an algorithm that reduces the effort to a single pass. It also reduces the amount of false errors during signal integrity analysis and speeds design debug to increase productivity.

"After a detailed evaluation of Nautilus-SI and CellXpert-CN's cell library noise characterization, we found the methodology fits well with our SoC-ImP(TM) technology, and gives us the best solution for our cell-based signal integrity analysis sign-off," remarked David Lyou, Socle's general manager.

Lyou added, "Compared with other cell library noise characterization methodologies, we found that CellXpert-CN offers a higher level of accuracy by taking into account the transition time and capacitive loading information found in our timing library. Nautilus-SI, with its cell noise library, gives our designers an accurate signal integrity tool for analyzing the effects of delay change and noise due to coupling without going through the full dynamic transistor-level analysis process. Working closely with Celestry's team, we have implemented this new methodology in our deep submicron design flow for signal integrity sign-off from the RTL (Register Transfer Level)."

Zhihong Liu, president and CEO of Celestry noted, "As part of our Silicon-Accurate Sign-off efforts, CellXpert-CN is the first product in our noise characterization family. Later this year, we will introduce more noise characterization products for intellectual property, memory and analog mixed-signal designs."

More About CellXpert-CN

CellXpert-CN provides noise characterization for standard cells as well as I/O cells, and supports combinational, sequential and tri-state logic cells. The inputs to CellXpert-CN are Spice model parameters, cell library-timing data in Synopsys (.lib) or Cadence (tlf) format and Spice/CDL circuit netlist with RC information. The output of CellXpert-CN is a noise library file (nlib).

About Nautilus-SI

For SoC design, Nautilus-SI offers full-chip signal integrity verification software for deep submicron multi-million cell designs. It incorporates 3D parasitic extraction technology to accurately determine coupling capacitance. With its delay analysis engine, it captures coupling effects on timing and identifies signal integrity problems due to coupling noise.

Price and Availability

Celestry's CellXpert-CN with Nautilus-SI is available now. Nautilus-SI with CellXpert-CN starts at $115,000 for a time-based license (TBL). The software runs on Sun Solaris.
