Virage Logic is expanding its 65nm IP products, with an eye towards tackling today's complex IC design challenges. The products are based on more than two years of early 65nm silicon successes.

Virage Logic pioneered a new class of semiconductor IP, called Silicon Aware IP, two years ago. It includes silicon-behaviour knowledge for better predictability and manufacturability of ICs.

"Because Silicon Aware IP understands the behaviour of silicon and is able to address post-silicon issues, it is key in helping designers maximise yield, lower test costs, increase reliability, speed time-to-volume and improve overall manufacturability," said Yervant Zorian, Virage Logic VP and chief scientist.

Virage Logic was the first IP company to tapeout a 65nm test chip, in December 2004. According to Zorian, an important criterion for 65nm designers is to really find a tradeoff among speed, power, area and yield to find the "sweet spot" for each design.

65nm solutions
At the International Test Conference this week, the company is announcing the availability of a broad new family of 65nm IP products. The SiWare Memory product line is said to provide a dashboard that enables SoC designers to explore those tradeoffs to generate optimal memory configurations. This "dashboard control" capability is critical at 65nm, where both design and process complexities require sophisticated management of the various tradeoffs in order to effectively meet stringent end-product requirements and increasingly narrow market windows, according to Zorian.

The complementary SiWare Logic product line offers SoC designers that same ability to manage tradeoffs between area, speed and power in logic ICs.

"Since the introduction of our 65nm offering with TSMC, UMC and Freescale in 2004, we have leveraged our early experience to provide designers with an advanced product offering that addresses tough 65nm challenges," said Brani Buric, VP of product marketing and strategic foundry relationships at Virage Logic.

Said Rich Wawrzyniak, senior analyst at Semico Research Corp: "I am impressed with the breadth of Virage Logic's new 65nm SiWare Memory and SiWare Logic offering and the attention to detail, in terms of providing a complete capability set."

Virage Logic is also releasing enhancements to its Self-Test and Repair (Star) memory system to address the challenges of advanced design and process technologies. Here, as well, a dashboard of user-selectable options enables tradeoffs between test time, area, and state-of-the-art diagnostics for optimal design-complexity management.

Star Yield Accelerator, another product option, expands Star's capabilities and bridges the design and manufacturing disciplines to enable automated test-vector generation, silicon analysis, fault isolation and classification to be used at the critical semiconductor tape-out, bring-up and volume manufacturing stages.

The Star Memory System will be open to enable licensees to use the system's capabilities with other commercially available and internally developed embedded memories.

"As process nodes advance, the risk and the costs of lost yield increases exponentially," noted Zorian. "With our latest release of the Star Memory System, licensees are well equipped to proceed with speed and confidence through the critical design and manufacturing stages, while optimising the profit opportunities their products represent."

"Licensees will be offered the flexibility mixing memories from various sources and still be able to reap the benefits of the Star Memory System's capabilities," said Buric.

The Star Memory System is available at project-based pricing starting at Rs.10.11 lakh ($25,000). Star Yield Accelerator pricing includes software and services for Rs.20.22 lakh ($50,000).

Eyeing inroads
Meanwhile, SiWare IP supports major IC-design tool flows by Cadence, Magma and Synopsys, and its project pricing starts at Rs.28.31 lakh ($70,000).

"The new developments are all based on practical data we have accumulated from real designs in the ten to 12 foundries we are working with, including TSMC and Chartered," said Zorian. "Some 75 per cent of an SoC is made up of memory, so providing the capability of identifying, characterising and classifying types of faults at the challenging 65nm node and below can greatly affect the overall chip yield."

Virage Logic is placing its bets on continuing to serve leading-edge designs in today's tough economic waters. During the last quarter, Virage Logic consolidated some of its operations, including the closing of a Seattle R&D site.

"While we were able to grow revenue 7 per cent sequentially, to Rs.45.71 crore ($11.3 million), we did not meet our minimum revenue guidance of Rs.46.52 crore ($11.5 million)," said Dan McCranie, president and CEO of Virage Logic, in the company's quarterly review. "Our opportunity pipeline is larger and increasing. We believe that these opportunities are a direct result of our focus, over the past six months, to develop new memory compilers and logic libraries at the most advanced process nodes, and our continuous improvement in product quality and delivery against agreed upon schedules."
