Synopsys to Release a Complete, Single Vendor Interface IP for High-Performance DDR2 SDRAM Memory Subsystems
Complete Solution Will Include Memory Controller and Mixed-Signal PHY to Reduce Risk and Speed System Integration

Synopsys, Inc. (NASDAQ: SNPS), a world leader in semiconductor design software, today announced that it will expand its DesignWare® Cores intellectual property (IP) with the planned release of a single vendor, complete system-level interface solution for high-performance DDR2 SDRAM memory subsystems. The new DesignWare IP will help ensure overall memory system performance of up to 800 megabits per second (Mbps) by delivering a complete DDR2 SDRAM memory interface solution that includes a scalable digital controller, a complete integrated physical interface hard macro and verification IP that supports state-of-the-art verification methods. Seamless integration between memory controller and PHY minimizes risk and maximizes performance. It also reduces overall system latency and enables more predictable success for designers using high-performance DDR2 SDRAM technology. The matching verification IP provides full support for VCS® Native Testbench for up to five-times faster verification performance, and further reduces the IP integration and system-level verification effort.

High-performance DDR2 SDRAM is an increasingly common memory solution for designs requiring improved data bandwidth capabilities, lower power and enhanced signaling features. However, the benefits of DDR2 SDRAM are coupled with significant physical implementation challenges that limit performance and increase the cost of implementation. Designers can spend a considerable amount of time managing integration and signaling details when implementing high-performance DDR2 SDRAM interfaces and IP acquired from multiple vendors. This situation increases design risk and may ultimately compromise the system's performance, especially at speeds of up to 800 Mbps.

With Synopsys' complete DesignWare DDR2 SDRAM solution, customers will be able to implement a proven, reliable high-performance complex memory interface in significantly less time than using discrete components allows. In addition, customers will benefit from the added level of system-level test, power management and signaling optimization not easily achieved using discrete memory interface IP components. The DesignWare DDR2 Memory Controllers offer distinct solutions targeted for a wide range of applications, from lean and efficient DDR2 protocol translations to full-featured multi-port with optimized scheduling operation.

The DesignWare Mixed-Signal DDR2 SDRAM PHY and DesignWare Cores DDR2 SDRAM Memory controller solutions will deliver predictable performance and increased margins, and will help considerably reduce implementation and integration time. Developed as a complete system-level interface IP solution, the DesignWare DDR2 SDRAM solution is designed to operate reliably across multiple interconnect topologies and packaging technologies.

"By providing a complete DDR2 SDRAM interface IP solution for our customers, we will significantly reduce the onerous and risky task of integrating discrete memory subsystem IP components. We will also reduce the interoperability challenges associated with the controller/PHY boundary," said Guri Stark, vice president of Marketing for the Solutions Group at Synopsys. "Solving these problems helps our customers concentrate on value-added portions of their designs instead of spending time trying to develop a high-performance DDR2 SDRAM memory subsystem. This ultimately saves design time and helps ensure that performance goals will be met."


Synopsys' DesignWare DDR2 SDRAM Memory Controller and Mixed-Signal PHY are expected to be available in Q1 of calendar 2007. The DDR2 memory model and AXI™ verification IP are included in the DesignWare Library and the VCS Verification Library and are available immediately.
