Cadence Accelerates Adoption of Emerging Mobile Standards with Expanded Verification IP Portfolio

Enables Users to be First-to-Market with Mobile Devices Leveraging Latest Standards

SAN JOSE, Calif., September 26, 2011 -- Cadence Design Systems, Inc. today announced new protocol and memory model verification IP (VIP) that will accelerate the adoption of the latest mobile standards. Through close collaboration with leading system and semiconductor companies, and standards bodies, Cadence is delivering VIP at a very early stage – in many cases, ahead of the final specification – helping mobile SoC and system manufacturers to be first to market with increasingly feature-rich mobile devices, such as smartphones and tablets.

In an interview with Low-Power Design, Susan Peterson, Group Director, Product Marketing at Cadence, explained that while memory models enable designers to do gate-level timing verification, they're tied to a specific chip, whereas Cadence's verification IP connects your code to a model of the specification, say USB To Go, so you can verify conformance to the spec before committing to specific hardware.

Peterson, who sits on a variety of specification working groups, claims that Cadence's participation in standards bodies enables their customers to get products to market faster, since they'll have verification IP in their hands sooner than they otherwise might. When questioned about the wisdom of promoting VIP for specs that aren't yet finalized, Peterson said she expected any last minute changes to be minor and reflected quickly in software updates.

Others at Cadence underscored the need for functional verification earlier in the design process. “The need for increased computing power and sophisticated video, audio and storage on mobile devices has given rise to new standards that improve performance and power, while reducing development time and cost,” said Ziv Binyamini, corporate vice president, research and development, System Realization Group at Cadence.  “In order to leverage these standards, our customers need solutions that can accurately test the functionality of their design and ensure manufacturing success.  Our extensive protocol expertise, combined with our track record of effectively verifying thousands of designs for over a decade, gives customers a proven path to success in the mobile market.”

“MIPI Alliance continues to advance mobile interface standards with processor and peripheral protocols that streamline system development and expand the sophistication of today’s mobile devices,” said Joel Huloux, chairman of the board, MIPI Alliance. “By ensuring verification support for these protocols at the earliest stage possible, companies such as Cadence enable mobile designers to embrace the latest standards and deliver products that transform the consumer’s mobile experience.”

Earlier this year, Cadence became the first company to add support for ARM Ltd.’s AMBA 4 Coherency Extensions protocol (ACE), speeding the development of multiprocessor mobile devices, and the DFI 3.0 specification, which defines an interface protocol between DDR memory controllers and PHYs.

Today, Cadence further expanded its VIP offering for mobile applications with support for the following standards:

  • LPDDR3: This low-power version of the pervasive DDR3 memory standard enables customers to meet the high bandwidth and power efficiency requirements of mobile systems.

  • MIPI CSI-3: Providing an advanced processor-to-camera sensor interface, MIPI CSI-3 enables mobile devices to deliver the bandwidth required to enable high resolution video and 3D.

  • MIPI Low Latency Interface (LLI): This interface cuts mobile device production cost by allowing DRAM memory sharing between multiple chips.

  • USB 3.0 On-The-Go (OTG): Providing 10x the performance of the previous USB specification, USB 3.0 OTG allows consumers to rapidly transfer data, such as video and audio content, as well as quickly and effortlessly charge devices.

  • Universal Flash Storage (UFS):  A common flash storage specification for mobile devices, UFS, a JEDEC standard, is designed to bring higher data transfer speed and increased reliability to flash memory storage.

  • eMMC4.5: Designed for secure, yet flexible program code and data storage, eMMC4.5, a JEDEC standard, enables high bandwidth, low pin-count solutions that simplify system design.

  • cJTAG: With its support for reduced pin count, power management and simplified multichip debug, cJTAG enables efficient testing of mobile devices, a key requirement for delivering high volume, high quality mobile devices.

The new memory models and protocol VIP will be available this month as part of the Cadence Verification IP Catalog.  Among the most comprehensive and robust in the industry, the catalog features support for over 30 complex protocols and models for over 6,000 memory devices.  The offering also provides maximum flexibility to customers by ensuring open support for all third-party simulators and design methodologies including UVM, OVM, and VMM.
