Synopsys TetraMAX II Speeds Test Generation for STMicroelectronics SoC Designs

MOUNTAIN VIEW, Calif., July 12, 2016 /PRNewswire/ —

Highlights:

Evaluation of TetraMAX II demonstrated an order of magnitude speedup in runtime
Achieves significant test-pattern-count reduction without impacting test coverage

Synopsys, Inc. (Nasdaq: SNPS), today announced that STMicroelectronics is seeing significantly faster test pattern generation runtime and reduced number of patterns with TetraMAX^® II ATPG. STMicroelectronics faces the challenges of increasing complexity and shrinking time-to-market schedules for their system-on-chip (SoC) designs. To meet these challenges, STMicroelectronics requires fast turn-around time (TAT) for generating high-quality manufacturing test patterns. Following an evaluation using a multi-million-gate FD-SOI SoC design, TetraMAX II demonstrated an order of magnitude speedup in runtime and significant test-pattern-count reduction without impacting test coverage. As a result, STMicroelectronics is deploying TetraMAX II in their standard SoC design flow.

“Over the past several years, we have collaborated with Synopsys to address the growing manufacturing-test challenges of increasing complexity and manufacturing test costs in combination with requirements for higher quality and faster TAT,” said Roberto Mattiuzzo, SoC integration and DFT methodologies manager in STMicroelectronics’ Digital and Mixed Processes ASIC division. “During our evaluation on a high-density FD-SOI chip, TetraMAX II produced test patterns an order of magnitude faster while significantly reducing the number of patterns without any coverage loss. With these results, we are confidently testing first-silicon samples earlier and reducing tester time, too.”

“Customers such as STMicroelectronics rely on Synopsys’ test solution to ensure the best combination of fast TAT and low test costs with high quality,” said Antun Domic, executive vice president and general manager for Synopsys’ Design Group. “Our long-term collaboration with ST continues to go from strength to strength. With the latest results from their TetraMAX II evaluation, we are demonstrating yet again our commitment to deliver continuous innovations in ATPG and related technologies to address our customers’ manufacturing test challenges.”

About TetraMAX II
TetraMAX II is built on new test generation, fault simulation and diagnosis engines that are extremely fast, exceedingly memory efficient, highly optimized for generating patterns and execute fine-grained multithreading of the ATPG and diagnosis processes. These innovations lead to significantly fewer test patterns and cut ATPG time from days to hours. The memory efficiency of TetraMAX II enables utilization of all server cores regardless of design size surpassing previous solutions that are limited by high memory usage. The reuse of production proven design modeling and rule checking infrastructure, as well as user and tool interfaces, ensure designers can quickly deploy TetraMAX II risk-free on their most challenging designs. Moreover, TetraMAX II utilizes established links with the Galaxy™ Design Platform tools, such as DFTMAX compression, PrimeTime® timing analysis and StarRC™ extraction, as well as other Synopsys tools, including Yield Explorer® design-centric yield analysis and Verdi® debug tools, to deliver the highest quality test and the fastest, most productive flows.
