Zenasis device offers up to four-fold runtime speed increase

The new timing optimization product from Zenasis Technologies Inc. brings cell-based designers a three to four-fold increase in runtime speed, allowing them to achieve timing closure in complex, high speed nanometer blocks up to 600K gates in a matter of days.

According to the company, ZenTime 2.1 is the only cell-based timing optimization product currently able to achieve timing closure for existing nanometer designs that have already been through logic optimization and physical synthesis.

"ASIC designers are facing continuing problems with timing closure for high speed designs. Mainstream synthesis and optimization tools are facing difficulty in meeting the timing constraints for 130nm and below processes and for clock rates beyond 300MHz, even using the best optimization techniques available," noted Dr. Rob Roy, VP of marketing & business development. "ZenTime can enable performance gains of 50MHz or more, making it the only tool capable of closing the large timing shortfalls that are common in nanometer-era designs."

The product uses a hybrid optimization technology, which helps ASIC and SoC design teams to reach their target performance by injecting design-specific optimized cells into their timing critical designs, resulting in large timing gains. Using a hybrid of transistor, logic, and physical level optimization, it can generate timing gains that are two to four times larger than gains achievable using conventional timing closure tools late in the design cycle.

The device improves timing performance by automatically identifying groups of standard cells in a critical path, and replacing them with custom-crafted design-specific cells, which have been optimized at the transistor level. The design-specific standard cells use the same architecture as that employed by a pre-existing standard cell library.

Production version of the ZenTime 2.1 will be available on June 2004. For term based licensing, it is priced at $195,000 per year.
