ScanPCI th - Corelis unveils the ScanPCI™ tester, enabling boundary-scan  (JTAG) testing of PCI and Compact PCI (cPCI) cardsCerritos, CA, August 8, 2003 — Corelis Inc., introduced today a new test module, ScanPCI, that was specifically designed to simplify the testing of PCI and cPCI devices and at the same time significantly increasing the overall test coverage. The ScanPCI module increases boundary-scan test coverage to the complete board assembly including the circuit traces and adjacent ICs that are directly connected to the card edge connector pins.

Previously, the traces and ICs that interface with the edge connector of the PCI and cPCI cards have either not been tested or required a special harness and custom testing hardware. The ScanPCI takes advantage of the JTAG interface built into the PCI bus to access the boundary-scan components of the PCI-based UUT and thereby greatly extends the total test coverage.

During testing, the PCI or cPCI card UUT edge connector simply plugs into the ScanPCI test module mating connector, allowing access to the boundary-scan controllable digital I/O pins provided by the ScanPCI. To increase overall boundary-scan test coverage of the UUT, the ScanPCI I/O pins are fully controlled through the serial boundary-scan bus and test patterns are applied to the ScanPCI pins synchronously with those applied through the UUT. The overall effect is an improved test procedure that substantially increases the testable portion of the UUT and is simpler, easier, and hence less expensive to construct and administer.

The ScanPCI module has an internal ATX style power supply and fully supports 3.3V and 5V compatible PCI and cPCI cards.

“The use of the ScanPCI module to simplify boundary-scan testing of PCI and cPCI boards, while simultaneously increasing test coverage by including edge connectors and associated interface logic, significantly lowers test development cost and greatly enhances test coverage. This effectively reduces time to market, lowers testing costs, and improves product quality.” said Jim Rodgers, Technical Marketing Engineer at Corelis.

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, cPCI, PCMCIA, LAN, PXI and VXI busses. Corelis also provides various engineering services and is well known for its outstanding customer support.
