Key Features

Industry-Leading Scan Test Tool

Tessent TestKompress uses Embedded Deterministic Test technology to achieve the highest
level of test quality while compressing scan patterns often 100X or more.


Highest Defect Coverage

Tessent TestKompress supports all traditional fault models used for uncovering both static and dynamically activated defects. Support for user-defined fault models (UDFM) also allows virtually any defect mechanism to be modeled and targeted.

Fully Automated

Tessent TestKompress is built on the Tessent Connect end-to-end automation platform, which offers comprehensive automation, TCL-based scripting, and introspection capabilities. To maximize throughput, automatic test pattern generation (ATPG) can be distributed across multiple processors.

Lower Test Time and Pattern Count

Built on the patented Embedded Deterministic Test (EDT) technology, Tessent TestKompress reduces both test time and pattern volume by several orders of magnitude without any loss in fault coverage.

IC schematics with light bursts | Tessent ScanPro includes the VersaPoint test point technology that directly targets ATPG pattern volume reduction of 2X to 4X in addition to increasing logic BIST test coverage.
