Synopsys Inc. has launched the DesignWare SATA Device IP, for use in applications such as solid-state drives (SSDs), HDDs and optical disk drives.

Additionally, Synopsys' comprehensive, DesignWare SATA IP solution consisting of device, host, PHY IP in 90- and 65nm processes, and Verification IP has passed the SATA-IO Building Block interoperability testing, demonstrating full SATA functionality from a single vendor. Synopsys offers IP solutions that help designers reduce the risk and cost of integrating the SATA interface into their SoC designs.

The Synopsys DesignWare SATA Device IP supports transfer speeds of 1.5Gbit/s and 3Gbit/s with a road map to 6Gbit/s, making it suitable for storage applications requiring high system performance. A proven component of the Synopsys Eclypse low power solution, the IP implements multiple aggressive power management features which can be utilized to lower the power consumption of the end application. The inclusion of a well-defined, DMA-based software programming interface helps designers achieve optimal system performance while maintaining low latency and minimal software overhead. Furthermore, the supplied example firmware helps reduce the overall software development, integration and maintenance effort.

With the release of the SATA Device IP, Synopsys now offers designers a comprehensive, silicon-proven and fully interoperable SATA IP solution consisting of the device, host, PHY and verification IP. The DesignWare SATA host controller supports Native Command Queuing and Asynchronous Notification in up to eight ports. The host controller is verified with the AHCI software drivers provided as part of the Linux and Microsoft Windows Vista OS, enabling designers to ease system-level integration. Complementing the host and device controllers is the robust, low power DesignWare SATA PHY, which includes built-in diagnostics allowing on-chip visibility into the link performance and ATE test vectors for at-speed production testing. The DesignWare verification IP helps designers quickly and efficiently create a comprehensive SATA-based environment. In addition, the SATA verification IP delivers up to 5x performance improvement when used with Synopsys' VCS simulation tool and is VMM-enabled to help speed the development of powerful SystemVerilog testbenches.

"The requirement for mass storage devices is continuing to grow, with SSDs estimated to increase at a 76 percent CAGR from 2007 to 2012," said John Koeter, senior director of marketing for IP and services at Synopsys. "By providing a complete DesignWare SATA IP solution that offers a strong combination of proven interoperability, low power, and ease of integration features, Synopsys enables designers to integrate the SATA interface into SoC designs with less risk and improved time to market."

The complete DesignWare SATA IP solution including device, host, PHY in 130-, 90- and 65nm processes, and verification is available now.
