ScanWorks^® JTAG Design Browser

Product Overview

The ScanWorks® design browser is a powerful, yet easy-to-use collaboration and communications tool that gives engineers, manufacturers and customers’ web-based access to electronic design data. The data is accessible for browsing graphically as either a printed circuit board layout or a schematic. The design browser provides the ability to visually pinpoint fault locations on a layout view and to view the fault coverage provided by the current set of boundary-scan tests. After running test actions, the fault location can be viewed by clicking the net name or pin number in the ScanWorks Net Failures Report or Advanced Diagnostics Report. Cross hairs pinpoint the fault location. In addition, selecting a device or pin allows you to view its properties or display the relevant part of the scan path. The fault coverage is viewed by generating a combined coverage report and clicking on the provided links. A link is provided to display the interconnect fault coverage report which contains links to display all the nets in each of the six coverage classes, from fully covered to no coverage. The combined coverage report includes links to display the opens coverage at the device and pin level. All fully covered devices (all pins covered) and all devices with no coverage can be displayed, as well as any partially covered device with the covered pins highlighted.

The design browser also provides ScanWorks Interconnect Test Generation access to detailed design information enabling test generation based on the same data used to build the board. Interconnect data is extracted directly from the design data files. Pin IO data is extracted (if available) and is used to determine if each net can be tested safely with boundary scan or JTAG.

Access Throughout Product Life-Cycle

The entire product from design through manufacturing and test can dynamically interact with design data throughout the design and manufacturing stages. Engineers can trace signal information quickly. Designers can participate in online design reviews. Purchasing can communicate with vendors the content of the actual design and hands-on managers can monitor progress of the project. The end result is a higher quality end product. Schematics and PCBs can be browsed, queried, and cross-probed without a need to have the original CAE or PCB CAD license. Extensive electrical information queries and comment annotations can be performed quickly and easily accessible by anyone with file access permission. The design browser also has the capability of outputting Bills of Materials and test point and routing topology data to Excel spreadsheets.

Using industry-standard interface formats such as EDIF, IFF, CADIF, DSN or GenCad as its standard database, the design browser may be used with any schematic capture or physical layout system such as:

Design Browser converts the input data into a data base format known as EDA files for fast access to the information. Some CAD tools vendors provide utilities to export data directly in the EDA format, avoiding the intermediate translation step.

The design browser is available in either node-locked or network license configurations and is included in the Test Development Station as well as the Diagnostic & Repair Station without additional costs. It is also available as a stand-alone product or as an option to the Interconnect Development Station or Manufacturing Station.
