Cerritos, CA, May 16, 2001  -- Corelis Inc., introduced today a new test module, ScanPCI-280, that adds boundary-scan test coverage to the circuit traces that are directly connected to the card edge connector pins. Previously, the traces connected to the edge connector of the PCI cards have either not been tested or required a special harness and custom testing hardware. The ScanPCI-280 takes advantage of the JTAG interface built into the PCI bus to access the boundary-scan components of the PCI-based Unit-Under-Test (UUT), and fully supports 3.3V and 5V compatible PCI cards.

Boundary-scan is an IC embedded technology for testing digital circuit boards and components that has been standardized as IEEE Std 1149.1. Test coverage using the boundary-scan standard has been limited to those devices that incorporate the required boundary-scan logic although non-boundary-scan devices can be tested if their I/Os are connected to boundary-scan components.

During the test, the PCI card UUT edge connector plugs into the ScanPCI-280 module mating connector allowing access to the boundary-scan controllable digital I/O pins provided by the Corelis’ ScanIO-280LV companion product. The ScanIO-280LV I/O pins are fully controlled through the serial boundary-scan bus, and test pattern can be applied to these pins. Furthermore, there are no limitations on test pattern depth since the ScanIO-280LV modules do not require pin memory and can be used to generate test vectors of any size.

“The use of the ScanPCI-280 module to augment boundary-scan testing of PCI boards to include edge connectors, significantly lowers test development cost and greatly enhances test coverage, thus reducing time to market, lowering test costs, and improving product quality.” - said Menachem Blasberg, president of Corelis Inc.

Corelis Inc., offers a broad line of boundary-scan software and hardware products for interconnect testing, in-system programming of Flash memories & CPLD's, JTAG emulation and debugging. It includes a full range of IEEE-1149.1 boundary-scan testers for the ISA, USB, PCI, PCMCIA, LAN, PXI and VXI busses. Corelis also provides various engineering services and is well known for its outstanding customer support.
