Mentor Graphics Corporation
(NASDAQ: MENT) today outlined its strategy and roadmap to help customers
address the growing test challenges they face in moving to smaller process nodes
and more complex, low-power, mixed-signal systems-on-chip (SOCs). As part of
this strategy, Mentor is uniting its award-winning embedded compression and
automatic test pattern generation (ATPG) technology with the leading built-in
self-test (BIST) technology from recently acquired LogicVision into a new product
line, called Tessent™. The Tessent line is the industry's most comprehensive
set of design-for-test and silicon test solutions, and also includes LogicVision's
SiliconInsight product, Mentor's layout-aware diagnosis tools and the
newly announced Tessent YieldInsight product to provide solutions for post-silicon
test characterization and yield analysis.
“Those who follow Mentor Graphics know that we target segments where
we can be in a strong number one position,” said Joseph Sawicki, vice
president and general manager for the Design-to-Silicon Division at Mentor Graphics.
“The combination of Mentor's market-leading scan-based test and
yield analysis products, and the LogicVision BIST solutions, puts us in the
top spot across the board in silicon test. We plan to grow from that position
of strength by taking the newly branded Tessent line broader and deeper, and
continuing to provide the industry's most complete and unified solution
for silicon test, diagnosis and yield analysis.”
“ON Semiconductor is committed to utilizing best-in-class ATPG and BIST
technologies for product development,” said Peter Zdebel, senior vice
president and CTO at ON Semiconductor. “We are enthusiastic about the
benefits that the single integrated product line from Mentor Graphics offers.
We have a longstanding relationship with Mentor in the DFT/ATPG arena that we
value and will continue to foster. We look forward to utilizing Mentor's
expanded silicon test and yield analysis product-line to provide our customers
with world-class products.”
Emerging Challenges in Silicon Test and Yield Analysis
Various drivers are making design-for-test (DFT) and implementation of production
test much more difficult than in the past. SOCs designed for 45nm processes
and below with low power requirements, embedded microprocessors and memory,
as well as analog circuitry and high-speed serial I/O, pose some extremely difficult
test challenges. As a result, customers are taking longer to plan, implement,
and bring up tests for their new ICs, and production test times and costs are
increasing. Moving to smaller nodes also increases design sensitivity to normal
manufacturing variability, introducing systematic failure mechanisms that are
difficult to find using traditional failure analysis techniques. This can lead
to a slower ramp-to-volume production and reduced profitability.
Mentor's Tessent Product Line Provides a Comprehensive Solution
Mentor's Tessent product line addresses these new challenges with a coherent,
interoperable suite of products that combine the best features of deterministic
scan test, embedded pattern compression, and BIST. Mentor offers the most comprehensive
range of test capabilities, which extends across all types of IC elements (logic,
memory, analog I/O), all phases of test design and implementation (test definition,
RTL insertion, test verification, test bring-up, silicon characterization, wafer
test, and package test), and all test methodologies (ATPG, embedded compression,
BIST, boundary scan, memory repair, test failure diagnosis, yield analysis).
Future Roadmap
Going forward, Mentor's BIST offerings will be based on the former LogicVision
platform and the ATPG offerings on Mentor's TestKompress® and FastScan™
platform. Although some of Mentor's former BIST products and LogicVision's
former ATPG products will be discontinued, they will continue to be supported
for existing customers until they transition to the new products. Mentor will
also continue to invest and develop mixed-signal BIST technologies for SerDes
high-speed I/O and PLL testing, as well as the SiliconInsight® product line
developed at LogicVision. Additionally, Mentor will continue to improve the
level of interoperability of all Tessent products, to expand the Tessent integration
flow to support the latest design flows and styles, and to add more functionality
to address specific emerging challenges related to test.
