Cerritos, California, June 22, 1998 — Corelis Inc., today introduced ScanPlus Debugger a low cost PC based software and hardware package that allows a user to quickly find opens and shorts on and between BGA devices and fine-pitch components that are JTAG compatible. The new ScanPlus Debugger provides interactive control and observation of all boundary-scan controllable inputs and outputs from a Windows 95/NT user interface.

ScanPlus Debugger includes a fully featured “pin browser” that provides a user with a powerful time saving means of viewing and selecting pins and/or groups of pins based on a device’s functionality. Data entry and display can be accommodated in binary, decimal, or hexadecimal formats and debug sessions can be created and saved for later use. Device and pins filtering combined with sorting, makes selection of pins, nets, and groups a snap. The ScanPlus Debugger can also apply data to inputs of clusters and read their responses if the clusters pins are accessible via boundary-scan components.

“The ScanPlus Debugger provides a simple, low-cost boundary-scan interactive debug tool that our customers have been asking for.” said Menachem Blasberg, president of Corelis, Inc. “This product is an invaluable tool for engineers doing hardware debug during prototype design verification and testing of boards that include JTAG compatible BGA devices and other fine-pitch components.”

The ScanPlus Debugger includes facilities to ensure the safety of the board circuitry during boundary-scan debugging. A safety menu selects how unspecified pins are treated during the debug session. Before performing an update of the outputs, the debugger performs a netlist based conflict check. This process consists of checking for output value conflicts on all boundary-scan compatible pins on each net that has outputs being set.

Corelis provides a wide variety of boundary-scan controller options for the ScanPlus Debugger including PC-ISA bus, a PCMCIA card for portable applications, and an Ethernet network controller for LAN-based applications.

The product ships with a comprehensive user’s guide with tutorials, which can quickly train a new user in several hours. A JTAG test demo board is also available from Corelis to facilitate training and demonstration of ScanPlus Debugger’s capabilities.

Corelis is a world leader in the field of boundary-scan JTAG testing, microprocessor development tools, and VXIbus test instruments. Corelis also provides various engineering services and is well known for its outstanding customer support.
