ETCompression offers unparalleled flexibility, quality and test cost savings
SAN JOSE, Calif. — May 23, 2006 — LogicVision, Inc. (NASDAQ: LGVN), a leading provider of yield learning solutions, today announced the availability of ETCompression, a deterministic test compression solution, targeted at chips designed at advanced nanometer scale technology nodes. ETCompression provides the first true at-speed launch-on-shift test application using LogicVision’s patent pending Burst-Mode™ test timing architecture. This provides both very high transition fault coverage as well as signal integrity screening through run-time control of internal scan rates and functional clock cycle spreading. About LogicVision Inc.
At-speed test has become a requirement for designers of today’s highly integrated circuits, as semiconductor manufacturers are faced with increasingly subtle defect mechanisms and new process-design interactions, resulting in an increasing number of performance and quality issues. ETCompression provides the unique ability to test chips at-speed, under conditions which simulate actual functional operation, and does so with substantial test time and test data volume reductions. The result is an unmatched level of coverage and quality, at a lower test cost.
ETCompression builds upon LogicVision’s industry leading embedded logic test solutions, including a hierarchical architecture that provides both high scalability and full core reuse leading to significant integration efficiencies and time-to-market savings. ETCompression can be used purely with compressed deterministic scan patterns, or be seamlessly complemented with the application of pseudo-random patterns to achieve the highest quality levels required in communication, consumer, storage and automotive devices.
Tool capabilities include:
• Over 10x test time and 100x test data volume reduction.
• Patent pending Burst-Mode™ test timing architecture for true at-speed test application and run-time programmable power management and characterization.
• IEEE 1500 compliant distributed test access architecture and patented core Shared Isolation for hierarchical test integration for minimizing area overhead and performance impact.
• Automated RT level test analysis, generation and insertion flow for fast test integration, including handling of unknowns, and automated fixing of violations.
• Full physical design flow integration, including automated generation of design constraints, synthesis scripts, timing analysis, formal verification and testbench generation.
"At advanced process nodes the industry needs to maintain test quality and good yields while containing test costs in order to remain competitive,” said Jim Healy, president and CEO of LogicVision. “Testing chips under functional conditions is essential to ensure ultimate product quality, and ETCompression offers this key capability, allowing users to execute a comprehensive SoC test plan efficiently while controlling costs.”
Pricing and availability
ETCompression is available immediately, and will be on display at the upcoming Design Automation Conference, July 24-28 in San Francisco, California. ETCompression works seamlessly with other LogicVision tools and is interoperable with all major physical design flows, including Cadence Design Systems, Magma Design Automation, and Synopsys.
