A new boundary-scan innovation from Corelis enables concurrent (gang) testing and in-circuit programming of Flash Memories and CPLDs for up to 8,192 boards
The new ScanExpress™ architecture provides for concurrent testing
and in-circuit programming with practically unlimited scalability.
Cerritos, CA, March 28, 2003 — Corelis Inc., unveiled a high-volume production boundary-scan test and in-circuit programming system, ScanExpress™, that enables concurrent (gang) testing and in-system programming of Flash devices and CPLDs for up to 8,192 boards using a single PC and a single operator. The ScanExpress™ family of products dramatically increases the test and in-system programming throughput by applying new, innovative, and proprietary techniques tailored specifically for optimizing boundary-scan operating speed.
ScanExpress™ concurrently applies test and programming vectors to each of its TAPs while simultaneously verifying results in hardware, at each individual TAP with sustained test clock (TCK) frequencies reaching 80 MHz. The ScanExpress™ High-Performance Boundary-Scan Test and In-Circuit Programming System is targeted specifically to users whose applications demand the highest possible scan vector throughput and high-volume production.
ScanExpress™ has an intelligent boundary-scan architecture that can be used in the testing and programming of devices, boards, or systems, compliant with IEEE Std 1149.1. The ScanExpress™ system offers excellent performance due to its large array of performance-enhancing innovations that increase test vector throughput. Boundary-Scan test vectors developed with Corelis’ ScanPlusTPG™ Test Program Generator can be executed directly on the ScanExpress™ system.
“With this new architecture, we are able to support the testing and in-circuit programming of extremely large, dense, and complex board assemblies in practically unlimited volume. The ScanExpress™ system is capable of not only concurrently testing and programming high-volume board assemblies but also concurrently verifying results. The verification process is performed concurrently for each individual TAP by hardware in real-time. All this can be accomplished at TCK speeds reaching 80 MHz, thus greatly reducing test and programming times” said Jim Rodgers, Technical Marketing Engineer at Corelis Inc. “An example of what this means for the user is that if it takes 2 minutes to test and program a single board, then it will also take only 2 minutes to test and program 8,192 boards. This translates to an effective test and ISP throughput of just one tenth of a second per board”.
The ScanExpress™ System is comprised of scalable components designed to work together to support an unlimited variety of concurrent testing and in-circuit programming configurations. Core elements of this system include the highly advanced PCI-1149.1/Turbo™ boundary-scan controller and the ScanExpress Runner™ software; a powerful, yet easy to use Test Executive designed specifically for high-volume applications. Additional modules can then be added depending on the volume demands of the user.
The ScanExpress™ system is available from stock with prices starting from $30,000.
