Nassda Updates Product Line With New Version 6.0 Release SANTA CLARA, Calif., March 28 /PRNewswire-FirstCall/ -- Nassda Corp. (NASDAQ:NSDA), a leading provider of full-chip circuit simulation and analysis software for the design of complex nanometer semiconductors, today announced the planned release of version 6.0 of its HSIMplus(TM), HANEX(TM) and CRITIC(TM) verification products in late April 2005. In version 6.0, the hierarchical simulator in HSIMplus includes improvements for DC convergence, transient analysis speed and modeling accuracy, to specifically address the challenges in verification of designs with multiple voltage domains implemented in 90nm and smaller processes, where power management is a critical issue. To extend the capabilities of HSIMplus for mixed-signal design verification, integration with Mentor Graphics' ADVance MS(TM) (ADMS) single-kernel mixed-language simulator is available in 6.0. This optional integration adds VHDL-AMS and Verilog-AMS co-simulation capability to HSIMplus, and adds hierarchical capacity and speed to ADMS. The co-simulation option is also extended to include the ModelSim(R) digital simulator. These integrations support both top-down and bottom-up verification flows by allowing for either the digital or circuit-level representation to be the top-level view for the design. Verification engineers can also run Verilog testbenches directly with HSIM without a separate digital simulation and translation step. The HSIMplus platform for dynamic transistor-level analysis of nanometer silicon effects is also enhanced in version 6.0 with the addition of the Physical Visualization Manager (PVM). The PVM generates GDSII layer maps to graphically depict results from the power and signal net reliability analyses performed by HSIMplus. PVM provides an easy to use graphical interface for analyzing the impact of IR drop in power grids, and diagnosing current density problems in nanometer wiring that can lead to device failure from electromigration. PVM is included with the HSIMplus power and signal net reliability analysis options. Nassda's HSIMplus 6.0 platform includes support for the Mentor Graphic's Calibre(R) xRC extractor, to create the industry's first fully hierarchical design flow for parasitic extraction and full-chip post-layout simulation of nanometer circuit behavior. This solution covers all types of hierarchical custom design, including memory, analog/mixed-signal and SoC. The combination of HSIMplus 6.0 with the Calibre(R) xRC extractor provides improved capacity and efficiency for verifying and analyzing nanometer designs and increasing their performance and yield. HANEX performs circuit-level timing and crosstalk analysis of leading-edge custom digital designs in 130nm processes and below. In version 6.0, enhancements include coverage of a wider range of design types, improved analysis of manufacturing variations on circuit performance and increased speed of analysis. Silicon-on-Insulator (SOI) semiconductor devices are now supported for low-leakage designs. Pseudo-NMOS structures are also supported for those custom digital designs that focus on maximizing speed and reducing the size of the circuit layout. Support for multiple process models allows designers to perform worst-case timing analysis across all process corners to verify correct behavior despite variations in IC manufacturing. Improved pattern matching and circuit partitioning algorithms enhance overall speed of analysis for complex designs. CRITIC performs post-layout timing analysis of clock and signal networks using critical path information from digital static timers such as Synopsys PrimeTime and Sequence ShowTime. CRITIC version 6.0 supports a streamlined crosstalk analysis flow and can utilize aggressor-only timing window data or can analyze worst-case path delay if timing windows are not available. For early analysis of timing behavior, before layout is complete, idealized clock analysis with balanced delay and slope is now available. If a digital standard cell timing model is not available, CRITIC version 6.0 can perform all of the transistor-level simulation necessary to compute cell and interconnect delay considering different input slopes and signal transitions. Digital static timers can use this delay data to compute new critical paths and increase the accuracy of timing closure in nanometer designs. "Nassda provides leading-edge technology circuit verification solutions for complex IC designs," stated An-Chang Deng, President of Nassda. "We believe our version 6.0 release further strengthens our technical leadership in nanometer circuit simulation and analysis. By continuing to enhance our HSIMplus platform, full-chip post-layout simulation is practical for verification of nanometer effects in complex designs. HANEX's support for multiple process corners and new design types such as SOI provides further improvements in both speed and accuracy for post-layout analysis. Crosstalk analysis with CRITIC is now even easier. Nassda continues to strive to enhance the capacity, performance and ease-of-use of its product line with each new release in order to support our broad customer's requirements." Other Version 6.0 Enhancements New CircuitCheck(TM) Enhancements The HSIMplus CircuitCheck option screens, identifies and reports potential circuit problems using static and dynamic checks before and during simulation. Developed in cooperation with customers working in the latest nanometer processes, the new improvements in version 6.0 include checks for signal nets subject to dynamic crosstalk noise, floating gate checks in power-down mode to expose possible causes of excess leakage current, and enhanced leakage checks for MOS devices. New Device Modeling To meet the demands for higher accuracy analysis in finer nanometer geometries and at radio frequencies, Nassda has expanded the set of supported semiconductor device models to include the SOI JFET model (MOS40). For analysis of long-term device reliability and aging effects, the MOS reliability analysis option of version 6.0 HSIMplus supports user defined models for the effects of hot carrier injection (HCI) and negative bias temperature instability (NBTI) of MOS devices. Analysis of these effects can help identify areas of a design where the behavior could change after thousands of hours of operation. Pricing and Availability The release 6.0 versions of HSIMplus, HANEX and CRITIC will be available in April 2005, and will run on Sun Solaris, HP-UX, Microsoft Windows and Linux platforms. U.S. time-based list prices start at $67,500 for HSIMplus, $58,500 for HANEX and $54,000 for CRITIC.
