Teseda and Mentor Graphics Partner to Speed Defect Diagnosis

PORTLAND, Oregon ─ October  24, 2008─Teseda Corporation, a leading silicon validation and failure analysis diagnostic company, announced today that they have partnered with Mentor Graphics to link Mentor Graphic’s YieldAssist toolset with the Teseda Diagnostic Environment.  This new capability will provide Teseda and Mentor customers with an integrated and truly layout-aware roundtrip flow that will accelerate their ability to rapidly diagnose scan failures down to the yield-limiting defects, and identify those defects in the physical layout.  The portability and low cost of the Teseda platform will allow more users access to the new iterative diagnosis capability in YieldAssist.  Coupled with the massive failure capture memory in the Teseda V-series systems, the YieldAssist tool will be able to iterate on even the most data-intensive defect candidates, such as defects in the scan logic.

The Teseda TWB Software will process test patterns from Mentor Graphics ATPG tools and run them directly on any Teseda TWB supported platforms, including the V520 and V550. The failure files are then passed to YieldAssist to analyze the test response and identify defect candidates. The resulting defect candidates can then be shown in the Teseda NetXY physical viewing environment. Optionally, the YieldAssist tool may be instructed to further isolate the candidates down to the most probable defect(s) by producing an iterative pattern set which can be immediately applied to the device-under-test though the Teseda Platform. This iterative process will yield the most probable defect candidate(s), which again may be highlighted in Teseda’s NetXY physical viewing environment.

NVIDIA adopts Teseda’s V550™ Debug & Diagnostic platform

Takes delivery of initial Silicon Validation and FA diagnostic platform

PORTLAND, OR-June 24, 2008 – Teseda Corporation, a leading provider of comprehensive scan-based diagnostic and debug solutions for semiconductor yield improvement, announced today that NVIDIA has taken delivery of their first V550™ system, and will be acquiring multiple systems. The V550™ is part of a unified system that integrates design, test, and diagnostic environments, leading to the rapid detection and repair of failures. The V550™ is the most powerful desktop validation platform in the industry, able to handle devices with up to 512 channels and providing more memory per channel than any other desktop system. When driven with Teseda’s powerful TWB™ software, it allows design teams to cut validation and diagnostic time, and FA teams to quickly pinpoint failure candidates.

Ramp Yield quickly with Teseda’s Diagnostic Manager Suite


In order to first ramp, then ensure stable production and high yield of today’s semiconductor technology, it is necessary to thoroughly analyze potential factors that may lower product yield and quality. Teseda’s Diagnostic Manager suite of tools provides important information and links to the wafer production and test process:
  • Identify the physical location of an electrical test failure
  • Provide the logical information for a suspect Inspection defect
  • Rapidly determine systemic defects from random defects
  • Analyze which defects have the largest impact on yield
Whether you collect the data from Teseda’s V5xx series of Validation and Failure Analysis platforms, your own ATE, or various inspection equipment, the DM Suite can be adapted to work with your data and integrate into your environment.
