ScanExpress Merge Screen - Corelis ScanExpress Merge™ Automates Boundary-Scan Testing and In-System Programming of Multiple Assembly SystemsCerritos, CA – January 3, 2006 – Corelis, Inc. today introduced ScanExpress Merge, a productivity enhancing software application that extends the use of boundary-scan tools to testing and programming multi-assembly systems composed of multiple boards, daughter cards, backplanes, connectors, and cables.  By preprocessing the test data files of each of the assemblies, ScanExpress Merge generates a unified set of input files that are compatible with Corelis’ ScanExpress TPG Test Program Generator. ScanExpress TPG will automatically process the merged assemblies and generate test vectors for the entire combined system, thereby extending boundary-scan testing and programming to the system level.

The ScanExpress Merge provides an exceptionally easy-to-use set-up Wizard that contains step-by-step instructions to ensure the user to enter the correct data for each module. A single click on the FINISH button initiates the merging of the test data.

ScanExpress Merge also automates the process of testing board IOs and traces that are connected to DIMM memory sockets and connectors. ScanExpress Merge combines the data of the board and the data of the ScanIO and ScanDIMM parallel IO modules into a single set of merged input files that are compatible with ScanExpress TPG. Adding support for boundary-scan parallel IO modules saves time by eliminating the need to describe the connections between the PCB connectors and the modules.

To further simplify operations, ScanExpress Merge automatically adds a prefix to the names of items that are associated with each assembly such as net names, device identifiers, etc. This allows the user to uniquely identify each assembly within the combined system and to properly diagnose faults when the complete system is tested.  The default prefix is optional for each of the merged assemblies and can be changed by the user.

“ScanExpress Merge is a powerful tool for test and development engineers” said Carmy Yellin, Vice President of Technology for Corelis. “It provides significant time savings when you need to test motherboard and daughter card assemblies, gang test multiple targets, test targets in a multi-card chassis and test assemblies connected via an external cable. In addition, it is all integrated with the intuitive user interface of our industry leading ScanExpress TPG”.

When connecting boards using a connector that plugs directly into a mating connector, ScanExpress Merge automatically finds and connects the relevant nets on both sides of the connectors. The user is only required to specify which connector(s) are mated.  This feature is very useful when using daughter cards that plug into motherboards or cards that plug into a backplane.

ScanExpress Merge automatically generates connection lists for mated connectors and generates suggested wire lists for connectors that are selected by the user to connect to Corelis ScanIO modules. This allows an engineer to follow ScanExpress Merge’s recommended connection list rather than having to prepare the ScanIO-to-UUT connection list manually.

ScanExpress Merge is now available for shipment from stock. Prices begin at $3,950. Contact Corelis at for more details.
