Installed on a PCÕs parallel port, the PIO-1149.1/E controller board is for use in testing IEEE 1149.1-compliant devices, boards and systems. The controller allows laptops to be used for 1149.1 boundary-scan (JTAG) testing of products over various phases of their life cycle. Among the controllerÕs features are an ability to execute boundary-scan test vectors directly on the PIO-1149.1/E, improved test vector throughput, user-programmable test clocks for speeds up to 25 MHz, and JTAG ports and discrete I/O voltage levels that are programmable from 1.25V to 3.4V and that are 5V compatible. The controller comes with built-in-self-test software, a scan function library, and device drivers. For more details, call Steven Hartman at CORELIS INC., Cerritos, CA. (562) 926-6727.
