New ScanExpressTPG™ Innovation from Corelis Dramatically Reduces Boundary-Scan Test Development Time
Cerritos, CA, February 3, 2004 — Corelis Inc. unveiled an intelligent automatic boundary-scan test pattern generation tool that takes the process of boundary-scan automation to a new level of performance and ease of use. By utilizing ScanExpressTPG™, both experienced and novice users can create boundary-scan test vectors in a fraction of the time it takes to develop test vectors using legacy test pattern generators. ScanExpressTPG™ has a built-in intelligent wizard that automatically displays the most relevant data and recommends the most likely selections when progressing through the various stages of preparing and generating test vectors.
The intuitive nature of the Graphical User Interface (GUI) guides the user through a logical sequence of steps. The steps start with a clear beginning, where a boundary-scan target project is defined, and ends with the actual execution of the newly created test plan. Each step guides the test developer with specific instructions as to what actions should be taken and how these actions affect the overall test process. The end result is a complete boundary-scan test procedure with the highest possible level of board test coverage.
Benchmark tests on a complex printed circuit board (PCB) with 8,180 nets (35,000 pins), including more than 50 memory clusters and over 30 logic clusters, showed that boundary-scan test development time could be reduced to less than a day while achieving very high test coverage.
“ScanExpressTPG™ is truly a next generation tool that significantly slashes boundary-scan test development time by automating and integrating many of the tasks that the user previously had to perform manually,” said Jim Rodgers, Technical Marketing Engineer at Corelis Inc. “A truly unique aspect of ScanExpressTPG™ is that the automation process does not diminish the flexibility, control, and visibility, that is often required when customizing specific boundary-scan tasks. Every feature and task available through manual test procedure creation remains available with the new automated approach”.
The ScanExpressTPG™ Intelligent boundary‑scan test generator program provides an integrated development environment (IDE) system in which the user can generate boundary‑scan tests from scratch, invoke the ScanPlusDFT™ Analyzer to produce test coverage reports, and invoke ScanPlus Runner to execute created tests, all from a single Graphical User Interface (GUI). The IDE type GUI was developed to provide a complete framework for boundary-scan test procedure development and execution. The GUI was designed to maximize clarity between the many separate aspects of employing boundary-scan. A direct connection between creating test files, report generation, and text execution is provided by the IDE.
Boundary-Scan is an embedded IC technology for in-system programming and testing of digital circuit boards and components that have been standardized as IEEE Std 1149.1. Corelis’ ScanPlus Boundary-Scan tools include hardware and software products offering exceptional ease-of-use combined with advanced technical innovation.
Corelis Inc., offers a broad line of boundary-scan software and hardware products for interconnect testing, in-system programming of Flash memories, CPLDs, FPGAs, JTAG emulation and debugging. It includes a full range of IEEE Std 1149.1 boundary-scan testers for the ISA, PCI, PCMCIA, LAN, USB 2.0, cPCI/PXI and VXI busses. Corelis also provides various engineering services and is well known for its outstanding customer support.
