Cadence, Realtek Collaborate to Reduce Risk of Functional Errors

Cadence Design Systems, Inc. (NASDAQ:CDNS) and Realtek Semiconductor Corp. (TSE: 2379) announced that they have collaborated to successfully reduce the risk of functional errors on its pilot multi-supply voltage (MSV) design. Realtek, a leading IC design house in Taiwan, adopted Cadence(R) Encounter(R) Conformal(R) Low Power and Encounter Conformal Constraint Designer to significantly reduce verification risks.

The Cadence product-segmentation strategy provided Realtek with multiple levels of technology tailored to specific levels of design complexity. Realtek used Encounter Conformal Low Power to perform functional and structural checks to find critical bugs introduced during low-power implementation. Encounter Conformal Constraint Designer helped Realtek ensure constraint quality by detecting inconsistent and conflict timing exceptions early in the design process, and to perform constraint validation to achieve faster timing closure.

“Due to our excellent prior experience with the Encounter Conformal technologies, we did not hesitate to deploy Encounter Conformal Constraint Designer and Encounter Conformal Low Power on this important multi-supply-voltage design project,” said Jessy Chen, executive vice president and spokesman for Realtek. “Encounter Conformal Low Power reported critical bugs in power connections after place-and-route that our designers were then able to confirm and address. Encounter Conformal Constraint Designer provided a complete verification solution to help our engineers solve a difficult constraint problem. We look forward to working with the Cadence Encounter Conformal R&D team to continue the growth and leadership of this technology.”

To face today’s low-power design challenges; designers require new tools and methodologies to help verify the correct implementation of low-power design techniques. Encounter Conformal technologies provide a unique combination of transistor abstraction, equivalency checking, and functional verification technology that enables customers to verify low-power designs.

“We are happy with the accelerated adoption of Encounter Conformal Constraint Designer and Encounter Conformal Low Power by the top semiconductor companies worldwide,” said Michael Chang, corporate vice president, R&D for Cadence. “Realtek’s ongoing positive results with our Encounter Conformal technologies confirm what the market has been telling us — Encounter Conformal is among the best formal verification technologies on the market.”

Encounter Conformal Low Power enables designers to verify and debug multimillion-gate designs optimized for low power. It combines low-power structural and functional checks with world-class equivalence checking to provide superior performance, capacity and ease of use. Encounter Conformal Constraint Designer automates constraint validation, generation, and refinement to ensure timing constraints are valid throughout the design process and help designers achieve rapid timing closure.

Encounter Conformal Low Power is available in XL and GXL offerings. Encounter Conformal Constraint Designer is available in L and XL offerings.
