ScanExpress TPG (Test Pattern Generator)

The ScanExpress TPG Intelligent Test Pattern Generator is a state-of-the-art automatic boundary-scan test pattern generation tool that takes the process of boundary-scan automation to a whole new level in performance and ease of use. ScanExpress TPG automatically generates test patterns that facilitate the pin-level fault detection and isolation of all boundary-scan testable nets on a printed circuit board (PCB). ScanExpress TPG also creates test vectors to detect faults on the pins of non scannable components such as clusters and memories that are surrounded by scannable devices. ScanExpress TPG accepts most industry recognized CAE/CAD netlists.

ScanExpress TPG provides an integrated development environment (IDE) in which the user can generate boundary-scan tests from scratch, invoke the ScanExpress DFT Analyzer to produce test coverage reports, and invoke ScanExpress Runner to execute generated tests, all from a single Graphical User Interface (GUI). The user starts with the basic board design files, adds supplemental information, generates test vectors, creates test coverage reports, and executes the tests by using the descriptive icons located on the shortcuts bar.

By utilizing ScanExpress TPG, both experienced and novice users can create boundary-scan test vectors in a fraction of the time it takes to develop these test vectors using legacy test pattern generators. Test development time is greatly reduced by automating and integrating many of the tasks that the user previously had to perform manually.

ScanExpress TPG greatly reduces the number of keystrokes and mouse clicks and eliminates text editing wherever possible. By maximizing the automation behind the complete process, boundary-scan test procedures can be developed with the least amount of time and effort while ensuring that the final test procedure is of the highest possible quality.

ScanExpress TPG also supports IEEE-1149.6, SerDes devices, BIST (Built-In Self-Test), and hierarchical bridge devices such as the TI 8996 ASP, TI 8997 Scan Path Linker, National SCANPSC110F, National SCANSTA111, National SCANSTA112, Firecron JTS06Bu, and Corelis ScanBridge.  For complete information on ScanExpress TPG, please refer to the detailed datasheet for this product.
