TESEDA AND SYNTEST TEAM ON FAILURE DIAGNOSTICS
FOR ADVANCED SOCS

Teseda Validation Systems Plus SynTest Diagnosis Software Shorten
Time For Diagnosing DFT-Based Designs

Portland, Ore. and Sunnyvale, Calif.,- August 18, 2003 - Portland-based Teseda Corporation, a leader in design-for-test (DFT) validation systems, and Sunnyvale-based SynTest Technologies, a leading provider of DFT technology, announced today that they are teaming to deliver fast, accurate failure diagnostics for deep-submicron, system-on-chip (SoC) designs. The two companies have partnered to streamline and facilitate communications between Teseda's V500™. and SynTest's new ATE-based debug and failure analysis software, TurboDiagnosis., for optimized discovery of device failures. The flow provides increased productivity and quality, as well as reduced cost to engineers who need to validate, debug, characterize, analyze, or sample integrated circuits (ICs) based on DFT.

The DFT Test Link

Teseda's V500 is a laptop-sized, affordable test system that design and product engineers use to accelerate DFT-based engineering test processes, such as chip and test validation and debug, fault isolation, and sample qualification.

The V500 system receives ATPG and testbench data from SynTest's DFT tools via an integrated, bi-directional communication link, then transfers the failure data to SynTest's debug and failure analysis software, TurboDiagnosis. TurboDiagnosis analyzes the data and automatically generates diagnostic patterns to precisely identify the failing node and discover the most likely causes of the defect.

TurboScan is SynTest's time-proven scan insertion and compact ATPG tool. VirtualScan provides scan insertion and compressed ATPG with VirtualScan capability to generate XtremeCompact™ scan test patterns. This reduces the cost of semiconductor testing by a factor of 5x to 50x through reduced test data volume, test run time, and test system reloads.
Together, the SynTest DFT and design-for-debug/diagnosis (DFD) tools, and the V500 create a fully integrated flow that minimizes the time-to-production for DFT-enabled devices. The integrated flow is based on the IEEE standard 1450 Standard Test Interface Language (STIL). The flow supports direct transfer of ATPG patterns from SynTest's TurboScan™ or VirtualScan™ to the V500 for engineering test.

"With SynTest's state-of-the-art DFT capabilities and our own expertise in DFT test, together we can now help mutual customers' engineers achieve faster time-to-volume with better test quality for their complex SoC designs" said Steve Morris, president and CEO, Teseda Corporation. "We are making it easier for engineers to have a cost-effective, smooth, and productive DFT flow with the integration to SynTest's platforms. Furthermore, this partnership lets SoC manufacturers realize dramatic cost savings over using traditional ATE as a tool for DFT-based engineering test."

"SoC markets today require shorter turnaround times to bridge the technical gap between design and production-test teams." According to Dr. L.T. Wang, president and chief executive officer, SynTest Technologies, "Providing customers with an automated diagnostic flow reduces the amount of time required for prototype debug and failure analysis and, more importantly, accelerates yield improvements and volume production of advanced SoC devices. This partnership with Teseda helps reduce the barrier between design and prototype test by linking best-in-class products in an intuitive and transparent flow."

ITC Attendees Can View Industry-First Demonstration
The complete design-to-test-to-diagnosis Teseda-SynTest flow will be demonstrated at the International Test Conference, in Charlotte, NC, Sept. 30 to Oct. 2, 2003 at the Teseda (#1029) and SynTest (# 1024) booths. Stop by or make an appointment for a demonstration.
