Encounter True-Time Maximizes Delay Test Coverage for Kawasaki Micro

11/8/2005 - Cadence Design Systems, Inc. (NYSE: CDN) (Nasdaq: CDN) announced that Kawasaki Microelectronics, Inc. (KME) has selected Cadence® Encounter® True-Time technology, the industry's first delay test ATPG that uses design timing to automatically generate faster-than-at-speed delay tests. Cadence also introduced two key enhancements to its delay test technology, True-Time for bridges and True-Time through RAMs.

Delay defects in nanometre-scale designs significantly slow interconnect timing transitions, which makes delay testing critically important. Traditional and existing at-speed delay testing solutions are limited in their ability to detect small delay defects, resulting in high test escapes, and system and field failures. Encounter True-Time delay test includes an on-board timing engine, which automatically generates faster-than-at-speed delay tests to detect small delay defects efficiently and deterministically, thereby minimizing test escapes.

"Effective transition fault ATPG testing is a key requirement to detect delay defects in nanometre designs—a problem that will only get worse at smaller process geometries," said Hiroyuki Nakamura, Manager, CAD Development Gr. 1, Kawasaki Microelectronics, Inc. "After extensive evaluation, we have chosen Encounter True-Time delay test for our flow, based on its ability to maximize test coverage by detecting the smallest delay defects, and support for on-product clock generation for path delay and transition fault tests."

Cadence's new True-Time for bridges allows users to automatically generate delay tests that target bridging fault models, a common nanometre design defect. This new technology allows multiple types of bridging fault models to be generated automatically from potential defect sites. True-Time for bridges enables users to specify potential bridging fault sites based on signal integrity or layout analysis.

Another new feature is True-Time through RAMs. This capability addresses customer requirements to generate delay tests into and through non-scannable elements, including third-party RAMs. These new features of Encounter True-Time delay test are fully compatible with Encounter Diagnostics, the industry's leading-edge yield diagnostics product.

"Our work with top semiconductor companies such as Kawasaki Microelectronics is a further endorsement of our differentiated advantage with Encounter True-Time delay test," said Sanjiv Taneja, vice president of R&D for Encounter Test at Cadence. "Detecting the smallest delay defects before system integration—and using Encounter Diagnostics to quickly identify their root cause—ensures the highest-quality, lowest-cost, highest-yielding ICs."
