Statistical, Variation-Aware Timing Analysis Required at 65-nm and Below
At advanced manufacturing process nodes, a statistically-enabled, variation-aware design flow is required for effectively managing the systematic and random process variations inherent in IC manufacturing. The SSTA flow featuring the Variety and GoldTime technologies enables designers to accurately account for these variations. It eliminates the need for designers to use pessimistic guard bands, which cause longer design cycles, bigger chip areas, and increased power consumption.
The accuracy of the underlying cell library used by GoldTime to predict the effects of variation on a design's timing and yield is essential for success. The development of this verified flow has qualified Altos as an Extreme DA-approved source for the nominal and statistical libraries required by GoldTime.
"We have worked with Extreme DA for more than eighteen months and have validated Variety's statistical timing models and Liberate's nominal timing models with GoldTime timing analysis," said Jim McCanny, Altos CEO. "Our joint customers are benefiting from improved characterization throughput and considerably lower disc space requirements especially for the creation of accurate statistical timing models."
"Statistical timing analysis relies on detailed characterization of variations in the cell libraries used by designers," said Mustafa Celik, president and CEO of Extreme DA. "Our collaboration with Altos has produced a powerful, verified statistical flow that can improve IC quality, increase yields, and accelerate time to market."
Availability and Pricing
Extreme DA GoldTime for use with Altos Variety and Liberate models is available now from Extreme DA. Pricing varies depending on configuration. Altos Variety and Liberate approved libraries for Extreme DA GoldTime are available now from Altos.
About Altos Variety
Variety creates statistical timing cell models that represent the non-linear impact of any number of systematic and random parameter variations. All library timing data is characterized for variation including delays, transitions, timing constraints, and pin capacitances. Variety generates SSTA models for a number of commercial SSTA products, including Extreme DA GoldTime, from a single characterization run.
Altos Design Automation provides ultra-fast, fully automated, characterization technology for the creation of library views for timing, signal integrity and power analysis and optimization. Altos advanced modeling solutions are used by both corner-based and statistical-based design implementation flows to reduce time to market and improve yield.
