MOUNTAIN VIEW, Calif., Nov. 5, 2012 /PRNewswire/ --Synopsys, Inc.
(Nasdaq:SNPS), a global leader accelerating innovation in the design,
verification and manufacture of chips and systems, today announced that
STMicroelectronics (ST) has adopted Synopsys' volume diagnostics solution
company-wide for faster yield ramp. IC product teams must rapidly isolate and
correct systematic failure mechanisms to ramp up new IC designs from low
initial yield to mature yield in volume production. Synopsys' solution has
enabled ST engineers to quickly identify the most dominant systematic failure
mechanisms on new designs, thereby driving yield improvement at a faster rate.

The solution is comprised of two integrated products from Synopsys: the
TetraMAX^® ATPG and Yield Explorer® tools. TetraMAX ATPG provides physical
diagnostics that enable the localization of defects on chips that fail logic
scan tests. Yield Explorer analyzes the defect locations from multiple failing
chips and correlates them with design data to prioritize systematic yield
issues and guide physical failure analysis. Integration of TetraMAX ATPG and
Yield Explorer into ST volume diagnosis flow has enabled ST to dramatically
shorten root cause analysis time and achieve rapid yield ramp on new designs.

"Recognizing that subtle systematic failures are critical to yield ramp at
nanometer process nodes, we collaborated with Synopsys to bring design, test
and manufacturing data together in volume diagnostics," said Roberto
Mattiuzzo, SoC Test and Diagnosis manager at STMicroelectronics' Central CAD
and Design Solutions. "Highly accurate physical diagnostics from TetraMAX
ATPG and Yield Explorer's design-centric data analysis and correlation
capabilities have allowed us to perform faster failure analysis and fab
process tuning. Among other benefits, this has resulted in significant
improvements in root cause isolation effectiveness hence leading to yield
improvements across multiple products/technologies."

The Synopsys volume diagnostics solution offers detailed engineering analyses
as well as automated production analysis and reporting. Expert users benefit
from the flexibility to bring design, fab and test data together and analyze
these with an exploratory approach. Time-sensitive production teams rely on
automated analysis routines to create various reports and provide a quick
first view of yield issues on new production batches. The integrated solution
is simple to deploy and offers a unified interface for physical design and
tester output data for higher efficiency.

"Yield Explorer easily accommodates the wide variety of yield analysis
requirements across our business units and is fully customizable to suit their
range of data types, analysis and reporting preferences," said Andrea Burri,
Supply Chain Solutions director at STMicroelectronics' Company Central
Planning. "In addition to being deployed for volume diagnostics, Yield
Explorer will be used by product engineers across ST to perform traditional
yield analyses based on functional, parametric and embedded memory tests."

"Systematic yield loss due to design-process interactions requires complex
analyses incorporating many different types of design data," said Howard Ko,
senior vice president and general manager of the Silicon Engineering Group at
Synopsys. "ST is a pioneer in recognizing volume diagnostics as the most
effective method to bring design data into yield analysis. ST and Synopsys
have collaborated in refining the Yield Explorer usage and TetraMAX ATPG
diagnostics during all phases of new product yield ramp so that design and
product engineers may easily use it across a wide range of products."
