Cerritos, CA, May 1, 2002 — Corelis Inc., today introduced a new ultra-high-performance, self-contained network-enabled, intelligent boundary-scan controller. The Net-1149.1/E integrates the power of a local area network into the entire boundary-scan development, production, test, and in-system programming process.  It provides an intelligent interface, with memory-behind-the-pin architecture, between any PC or workstation that has networking support for TCP/IP protocol over Ethernet and any JTAG compatible Unit Under Test (UUT).  It supports the 10Mbps and the Fast Ethernet 100Mbps (IEEE 802.3) protocol.

The IEEE-1149.1 JTAG Test Access Port (TAP) has programmable TCK clock rates up to 40MHz, and also includes 4 general programmable purpose I/O lines, individually controlled, for remote control and sense. The Net-1149.1/E serializes to the JTAG Test Access Port (TAP) boundary-scan instruction and test vectors which are previously loaded by the host over the network. The UUT responses are stored in the on-board 16 Mbytes of dual-port memory and uploaded to the host for further analysis.

A high-performance 32-bit RISC processor receives data from the UUT and provides only relevant information to the host without host intervention. This assures maximum test throughput and frees the host of the overhead involved in serializing the boundary-scan data, thus enabling the user to achieve higher test speeds.

“Utilizing the Fast Ethernet protocol, boundary-scan test vectors can now be loaded to the Net-1149.1/E and applied to the unit under test at previously unachievable speeds. This results in increasing test throughput and reducing in-system programming times. For very long tests such as Built-In Self-Test, the Net-1149.1/E frees the host to perform other tasks while testing is in progress.” said Menachem Blasberg, president of Corelis, Inc. “The standard 16 Mbyte on-board pattern memory, allows sufficient vector depth to handle test applications involving complex ASICs and highly populated boards without the need to reload the memory.”

High-level software to support for the Net-1149.1/E is provided by the Corelis ScanPlus family of software products. These Windows 95/98/NT/2000/Me/XP products offer Automatic Test Pattern Generation (TPG), test execution, in-system programming of CPLDs and flash memory, and fault diagnostics for boards.

A Scan Function Library (SFL) for Windows 95/98/ME/NT/2000/XP, UNIX and Linux is also supplied with the product to allow the end user to create powerful customized test programs.  The Net-1149.1/E controller ships with built-in self-test software and Plug and Play Windows 95/98/ME/NT/2000/XP Scan Function Library and device drivers.

Boundary-Scan is an embedded IC technology for in-system programming and testing of digital circuit boards and components that have been standardized as IEEE Std 1149.1.  Corelis’ ScanPlus Boundary-Scan tools include hardware and software products offering exceptional ease-of-use combined with advanced technical innovation.

The Net-1149.1/E is available from stock.
