About Teseda - Overview

ScanXY™, The first product in the Teseda Diagnostic Manager™ series, quickly links structural test mismatch data to its physical domain for rapid analysis and diagnosis of defects and hot spots.

The incorporation of scan-based testing drives the need for scan-based diagnostic software provided in the Teseda Diagnostic Manager™ Series. ScanXY™ bridges design, test, manufacturing and failure analysis by providing the logical to physical correlation using the benefit of your scan architecture.



Graphically view physical
locations of mismatches

ScanXY™ interprets physical design information and failure files and highlights reported mismatches of failed test results to the capturing scan cell in a physical XY location on the die. No other third party tools are required to view and analyze results.

Immediately begin yield learning with single or stacked results on volumes of failing structural test data from multiple devices or die on a wafer. ScanXY™ is integrated with the Teseda WorkBench™ so it easily imports results from the Teseda V500™ Series platforms or any ATE hosting the TWB. Also available in stand alone to read in EDA or ATE failure files formatted from your test database or ATE.



Determine the mismatching scan
cell based on pattern

Teseda’s ScanXY™ with its easy-to-use graphical user interface with point-and-click commands lends itself well to design, test, production and failure analysis engineers. ScanXY™ is integrated into the Teseda TWB™ environment or can be used stand alone for any diagnosis environment. Hardware platform and test software independent, ScanXY™ can be customized to support any failure file formats.
