Having worked with hundreds of customers to integrate earlier generations of this important memory controller interface, Cadence and the newly acquired Denali team offer the proven, high-quality IP and sophisticated integration environment required to speed integration, reduce cost and ensure design manufacturability. The solution includes hard and soft PHY IP; controller IP; memory models; verification IP; tools and methodologies; and signal integrity reference designs for the package and board.
“Memory management IP is central to successfully delivering differentiated products, and the quality of the IP dramatically impacts the performance, power and signal integrity of the entire SoC and system,” said Vishal Kapoor, vice president of the SoC Realization Group for Cadence. “Many designers are finding it increasingly challenging to design and integrate memory management IP onto their SoCs. As the only company to support its high quality IP with an integration environment spanning every aspect of design – from silicon to package to board – we dramatically lower the risk associated with realizing complex DDR4-based SoC designs.”
The DDR4 specification, an evolutionary SDRAM memory technology standard currently under review at JEDEC, proposes speeds ranging from 1600 mega transfers per second (MT/s) up to 3200 MT/s, more than 50 percent faster than the current DDR3 standard. As the standard evolves to support higher frequencies and throughput, signal integrity, power and performance issues multiply. Successful IP integration hinges on both the quality of the IP and the sophistication of the integration environment. The Cadence integration environment enables customers to model and analyze their target memory topology, and verify the behavior of the IP at both the SoC and system levels.
The soft PHY and controller provide tremendous flexibility and can be synthesized to support the full range of frequencies and voltages. Designers can deliver either a pure DDR4 SoC, or combine DDR4 with other technologies like DDR3 or LPDDR2. The specification is expected to be finalized this year.
“We expect vendors, especially in the networking and enterprise markets, to begin designing equipment utilizing DDR4 in 2012,” said Ganesh Ramamoorthy, principal research analyst, Gartner. “Since SoC designs start well in advance of system design, we believe the demand for DDR4 IP will begin from now on and grow strongly to reach peak demand by 2014.”
Cadence Further Defines and Extends Its SoC Realization Strategy
As part of the announcement today, Cadence further detailed its SoC Realization strategy, a key tenet of the EDA360 vision outlined last year. SoCs require integrating IP solutions from three primary categories: memory and storage, interface, and compute.
Given the significant impact that memory controller IP has on the overall performance of the SoC and system, Cadence is expanding the in-house development of comprehensive memory and storage controller IP to ensure maximum robustness and performance. The company plans to continue Denali’s tradition of developing high-quality IP in parallel with industry standards, giving customers the ability to be first-to-market with differentiated SoC solutions. The company also plans to support its IP with a comprehensive integration environment that is unparalleled in the industry.
For interface IP, Cadence will offer high-performance interface solutions, such as PCI Express Gen2 and Gen3, as well as Gibabit Ethernet (GbE), 10 GbE and 40 GbE solutions. The combined Denali and Cadence services team offers decades of design expertise, and will continue to deliver highly optimized, integrated IP solutions.
In the compute category, Cadence will continue to collaborate with leading IP providers to ensure it can support the compute needs of SoC designers. The group’s primary focus will be on ensuring successful integration through advanced methodologies, tools and reference flows that take a holistic approach to SoC design and verification.
