Cadence and SMIC Collaborate on Delivery of Low-Power 28nm Digital Design Reference Flow

Full Suite of Cadence Digital Tools Improves Designer Productivity from RTL-to-Signoff

SAN JOSE, Calif. - Cadence Design Systems, Inc. (Nasdaq: CDNS), today announced a collaboration with Semiconductor Manufacturing International Corporation (SMIC) on the delivery of a 28nm design reference flow that incorporates a full suite of Cadence® digital products for low-power design. This reference flow is a 28nm low-power register-transfer level (RTL) to signoff flow based on the IEEE 1801 low power design and verification standard. It enables system-on-chip (SoC) developers to deliver designs with optimal power consumption, performance and area (PPA), speeding time to market to satisfy ever-increasing computer, consumer electronics, network and wireless product market requirements.

The Cadence tools that provide comprehensive support from RTL-to-signoff include:

    --  Innovus™ Implementation System: A next-generation physical

        implementation tool that incorporates a massively parallel architecture,

        enabling SoC developers to deliver high-quality designs with highly

        competitive PPA. The tool also provides key technology for the 28nm

        process that supports floorplanning, placement and routing with

        integrated color-/pin-access-/variability-aware timing closure, and

        clock tree and power optimization

    --  Tempus™ Timing Signoff Solution: A comprehensive timing analysis tool

        that significantly reduces signoff timing closure through massively

        parallel processing and physically aware timing optimization while also

        delivering silicon-accurate timing and signal integrity analysis to

        ensure operational chips post-tapeout

    --  Voltus™ IC Power Integrity Solution: A full-chip, cell-level power

        signoff tool that provides accurate, fast, and high-capacity analysis

        and optimization technologies to designers for debugging, verifying, and

        fixing IC chip power consumption, IR drop, and electromigration (EM)

        constraints and violations, accelerating IC power signoff and overall

        design closure

    --  Voltus-Fi Custom Power Integrity Solution: A SPICE-level accurate,

        transistor-level tool used to analyze and signoff analog, memory and

        custom digital IP blocks and create accurate macro models that represent

        the power grid view of the IP blocks during the SoC power signoff run

        with Voltus IC Power Integrity Solution. It supports comprehensive EM/IR

        design rules and requirements for the 28nm SMIC process down to the

        transistor device level

    --  Conformal® Low Power Verification: Enables the creation and validation

        of power intent in context of the design, providing full-chip

        verification of power-efficient designs

    --  Genus™ Synthesis Solution: A next-generation RTL synthesis and

        physical synthesis engine that improves productivity challenges faced by

        RTL designers, delivering up to 5X faster synthesis turnaround times and

        scaling linearly beyond 10M instances

    --  Quantus™ QRC Extraction Solution: A next-generation parasitic

        extraction tool that is production proven and provides faster runtimes

        for single and multi-corner extraction and best-in-class accuracy versus

        the foundry golden reference

    --  Cadence Physical Verification System (PVS): A solution that supports

        full-chip and in-design signoff. PVS is tightly integrated with the

        Virtuoso® Custom IC platform, the Innovus Implementation System and the

        Quantus QRC Extraction Solution to significantly reduce iterations and

        achieve fastest time to tapeout

    --  Cadence CMP Predictor: Accurately predicts multi-layer thickness and

        topography variability using a model-based approach developed with a

        model calibration tool, Cadence CMP Process Optimizer, and identifies

        potential problem areas (hotspots) that affect yield

    --  Litho Physical Analyzer (LPA): Detects manufacturability issues missed

        by traditional design rule checks, which helps designers improve yield

        during physical implementation in a fraction of the time when compared

        with solutions based on optical proximity correction (OPC) and

        lithography simulation

"We've worked closely with Cadence to jointly develop the 28nm reference flow so that our customers can easily implement high-performance, low-power mobile processor chips," said Tianshen Tang, senior vice president of Design Services at SMIC. "The integration between the innovative tools from Cadence and our 28nm technology allows design teams to improve productivity and deliver reliable designs to market faster."

"The collaboration between Cadence and SMIC enables our mutual customers to quickly deploy the advanced suite of Cadence digital implementation and signoff tools in order to achieve optimum power and a faster path to design closure," said Dr. Anirudh Devgan, senior vice president and general manager of the Digital Signoff Group and the System & Verification Group at Cadence. "The optimized flow enables designers to apply these innovative technologies in order to achieve optimal PPA on the SMIC 28nm process."
