Just when it appeared they would actually take it to a courtroom trial, Cadence Design Systems, Inc. and Synopsys, Inc. settled the lengthy litigation known formally as “Cadence Design Systems, Inc. et al. v. Avant! Corporation et al.,” in the United States District Court for the Northern District of California.

Per the settlement, Cadence will be paid $265 million. In addition, Cadence, Avant! and Synopsys, as the acquirer of Avant! have entered into reciprocal licenses covering the intellectual property at issue in the litigation.

Ray Bingham, president and CEO of Cadence said the settlement “underscores the integrity of the laws that protect and thereby enable innovation. With the litigation behind us, our resources -- and those of Synopsys -- can be more focused on providing solutions for the technology challenges faced by our customers. I believe that the electronic design industry now can move forward in a spirit of cooperation and healthy competition.”

Dr. Aart de Geus, chairman and CEO of Synopsys add that while they do not condone the actions taken against Cadence in the past by Avant!, they also acknowledge the damage that it has caused to Cadence. “Today's agreement puts this matter to rest for good. We are pleased that we were able to work constructively with Cadence in order to resolve this matter. We are hopeful that the settlement will open a new chapter to a more mature and healthier electronic design industry going forward.”

Cadence will be paid $265 million in two installments: $20 million to be paid on or before November 22, 2002, and $245 million to be paid on or before December 16, 2002. The amount will be paid by Illinois National Insurance Company, a subsidiary of the American International Group (AIG), insurer for Synopsys, under an insurance policy purchased by Synopsys upon the completion of its acquisition of Avant!

Product News

Aptix Corporation rolled out Aptix Prototype Studio, which the company reported extends the benefits of Aptix prototyping technology to developers of custom multi-FPGA PCBs and has support for Aptix prototyping products: System Explorer and Software Integration Station (SIS). It provides a complete RTL to pre-silicon prototype (PSP) flow, regardless of whether the target is a hardwired or reconfigurable PSP.

Aptix Prototype Studio includes Aptix Design Pilot, supports partitioning a monolithic SoC design across multiple FPGA devices, works within the pin constraints of the FPGAs, maps SoC constructs like gated clocks into structures more appropriate for FPGAs, and debugs with the PSP when problems are uncovered in the design, the company said. Aptix Prototype Studio supports the latest Xilinx FPGA devices.

Aptix Prototype Studio is available in three forms.
  • Aptix Prototype Studio/PCB is available to designers targeting only hardwired PCBs.
  • Aptix Prototype Studio/Pro supports Aptix traditional reconfigurable prototyping products, System Explorer and Software Integration Station.
  • Aptix Prototype Studio/Enterprise supports all hardware targets.
  • Additionally, the link from the Aptix prototype database to a hardwired PCB utilizes FPGA Connector from Translogic, which automatic creates homogeneous and heterogeneous symbols to interface to industry standard schematic editors, in order to reduce the setup requirements for symbol creation into minutes. The link converts HDL descriptions into pin constraints for FPGAs and includes version management to ensure database consistency and accuracy. This use model promotes parallel engineering efficiency for schematic entry, FPGA place-and-route and board layout, the company said.

    XYALIS introduced GTsmooth, a hybrid metal-fill tool to address CMP issues. GTsmooth uses a model-based approach to identify where dummies must be inserted and follows a rules-based approach to determine how to insert dummies, to minimize thickness variation over chips and wafers, limit CMP effects and increase yield.

    To determine areas where dummy tiles need to be inserted, GTsmooth evaluates the thickness variation over the chip with a proprietary post-CMP thickness estimator, based on XYALIS' years of experience in the CMP domain. The GTsmooth approach is highly flexible and supports any process, since users may plug-in their own post-CMP thickness estimation function, based on the foundry expertise.

    To limit the number of added dummies, reduce the parasitic capacitance variation and minimize performance degradation, XYALIS has implemented a patented algorithm for metal-fill that makes sure that a minimum number of dummies are only added where needed. GTsmooth inserts up to 95 percent less tiles than rules-based tools for maximum yield improvement, the company said.

    GTsmooth inserts a small number of tiles, regularly spaced, so that the computation time is fast without database explosion, enabling designers to insert dummy tiles early in the design process and take their parasitic effects into account during timing verification.

    A last dummy tile insertion step is usually required at wafer level just prior to manufacturing after the process engineer adds test and alignment features to sawing lines. This last modification to the layout breaks the regularity and dramatically increases the size of the wafer-level database. XYALIS' optimizations in terms of computation time, memory and disk usage allow GTsmooth to handle such wafer-level dummy tile insertions.

    0-In Design Automation announced CheckerWare monitors for the AGP 8x, HyperTransport, InfiniBand and RapidIO standards. Leading IC design teams and ABV users can increase verification productivity by utilizing these pre-verified Verilog register transfer level (RTL) monitors to validate compliance with the latest protocol and interface standards, the company asserted.

    CheckerWare monitors are developed with leading customers as part of 0-In's continuing commitment to promote industry standards through the support of open standards. The capabilities of 0-In monitors include formal tool support, testbench and simulator independence, and interoperability with all tools in existing verification environments. Using 0-In's CheckerWare monitors, designers eliminate the time spent on developing and debugging protocol monitors and are free to devote more time to design and verification.

    CheckerWare monitors certify that the designs conform to interface standards and enable products to be interoperable with all products that support these standards. During simulation, CheckerWare monitors warn users of any protocol violations and generate structural coverage statistics to measure testbench efficacy. The same monitors serve as targets and constraints to guide formal verification tools, including the 0-In Search dynamic formal verification tool.

    A free NanoCool online seminar on Wednesday, November 20, 2002 at 11 A.M. PST, will offer an examination of low-power IC design issues, while detailing the tools and techniques necessary for success in the sub-100 nanometer realm, according to Sequence Design, Inc.

    Registration for the seminar, sponsored by Sequence Design, a founding member of the NanoCool Initiative for low-power design, is now open online at:

    According to Dr. Susheel Chandra, Sequence senior vice president of R&D and product marketing, concerns over power consumption are no longer limited to designers of ICs for portable applications, but for other types of design as well.

    Power reduction techniques are applied at every stage of low-power design, with analysis serving as a gauge for the amount of power reduced. In a power-management flow, early analysis guides the power reduction efforts. At the final stages of the design process, power analysis is again used to ensure that the power specification is met, or that power wastage has not been introduced.

    Additional information about the low-power seminar and other Sequence events may be obtained via e-mail at
