DecaWave Deploys Synopsys TetraMAX II ATPG on Latest Auto Design

Nov 2, 2017
 

Synopsys, Inc. has announced that DecaWave, a manufacturer of low-cost, low-power indoor positioning ICs and modules, deployed TetraMAX® II automatic test pattern generation (ATPG) to significantly reduce runtime from nine hours to thirty minutes and reduce the number of patterns by 50 percent compared to their previous test pattern generation solution for an automotive ultra-wide band transceiver IC. The lower pattern count enabled DecaWave to meet the challenge of high-quality manufacturing testing within a limited amount of tester time. DecaWave incorporated the TetraMAX II solution into their flow with minimal effort and produced improved results within an hour. As a result of this success, DecaWave is standardizing on Synopsys' TetraMAX II solution for all future designs to minimize silicon test costs and maximize test quality.

"Because our automotive IC requires high-quality testing with very few patterns, we decided to try TetraMAX II," said Gavin Marrow, vice president of technology at DecaWave. "TetraMAX II met our stringent requirements, creating 50 percent fewer test patterns compared to our prior ATPG while running 10x faster. Furthermore, we were able to include TetraMAX II in our design flow within only a few minutes and generate patterns immediately. Given the results, we believe TetraMAX II will meet our needs for high test quality across all our designs."

TetraMAX II ATPG is built on new engines that are extremely fast, memory efficient and optimized for generating patterns and diagnosing defect parts. These innovations lead to significantly fewer test patterns and cut runtime from days to hours. The TetraMAX II solution enables use of all server cores regardless of design size, surpassing previous solutions. The ability to reuse production-proven user and tool interfaces ensures designers can quickly and confidently deploy TetraMAX II ATPG on their most challenging designs. The TetraMAX II solution uses established links with Synopsys® Design Platform tools such as DFTMAX TM compression,

PrimeTime® timing analysis and StarRCTM extraction as well as other Synopsys tools including Yield Explorer ® design-centric yield analysis to deliver the highest quality test and the fastest, most productive flows.

"Synopsys is responding to the need for higher test quality for all of our customers, including those developing automotive ICs, such as DecaWave," said Bijan Kiani, vice president of product marketing at Synopsys. "The success at DecaWave demonstrates the benefits gained from our on-going development of breakthrough technologies, such as those delivered in TetraMAX II ATPG, to meet evolving design and test requirements."
