Cerritos, CA, July 15, 1995 — Corelis Inc., today unveiled a new high performance boundary­scan Controller board for the industry standard PCMCIA PC Card bus capable of supporting two independent JTAG ports with memory behind the pin. Additional individually programmable 16-bit parallel I/Os are provided to test or control non-boundary-scan areas of the unit under test. The PCMCIA-1149.1 allows a lap-top computer to be used for boundary-scan testing in various phases of a product life cycle such as design, manufacturing, and field service.

Boundary-scan test vectors developed with Corelis’ SCANTEST™ Automatic Boundary-Scan Test Pattern Generator (ABTPG) and its accompanying diagnostics software package can be executed directly on the PCMCIA-1149.1 controller. A software Scan Function Library (SFL) written in C is supplied with the tester card to allow the end user to create powerful custom test programs using high-level programming languages.

With the proliferation of the boundary-scan test standard in electronics manufacturing, users are expanding the use of the boundary-scan test logic beyond the scope of just interconnect testing. These new uses include JTAG emulation and source-level debugging of microprocessors, in-circuit programming of CPLDs, functional device testing of ASIC’s using the INTEST scan capability, and functional testing of non-scanable cluster logic on the unit under test. These forms of scan based testing usually require large test vector sets and tend to increase test execution times. The new Corelis PCMCIA-1149.1 controller is ideally suited for such applications due to its dual independent TAP controllers, on-board memory, and high sustained TCK clock speed.

“With this new controller design, we are able to support scan chain lengths of 4 Giga bits and TCK speeds of up to 25 MHz, thus greatly reducing test times” said Menachem Blasberg, president of Corelis Inc. “By having a common test platform for design, manufacturing, and field service, our customers will realize tremendous costs savings. This new controller is an important addition to our existing line of boundary-scan controllers as we can offer our customers a wide selection of tester platforms, speeds and prices”.

The PCMCIA-1149.1 scan controller requires a single PCMCIA Type II slot, and comes bundled with a Terminate and Stay Resident (TSR) Client Driver for automatic card configuration. The PCMCIA-1149.1 also includes self-test diagnostics routines, Scan Function Library (SFL), and a user manual. Delivery is from stock.

Corelis Inc., based in Cerritos, California, offers a broad line of boundary-scan software and hardware products including Automatic Test Pattern Generation (ATPG), diagnostics, vector translators and a full range of IEEE-Std 1149.1 boundary-scan testers for the PC ISA bus, VXI and IEEE-488.2. Corelis also provide test services, consulting, test vector translation, support and training.
