The Design Browser visually displays design data as either a printed circuit board layout or as a schematic. After boundary-scan tests are generated, the Design Browser will show the fault coverage provided by the tests. Once tests are applied to the board, the browser will graphically pinpoint the location of each fault. From the ScanWorks Net Failures Report or the Advanced Diagnostic Report, clicking on a net name or pin number will graphically show the fault location in a cross hair on the board design. In addition, selecting a device or pin displays its properties or the relevant part of the scan path where the device or pin is located.
The ScanWorks fault coverage report is linked to the Design Browser. The browser will display which nets fall into each of the six coverage categories, from no coverage to full coverage, that make up the report. The fault coverage report also offers links to the Design Browser where all opens at the device and pin levels can be displayed. Other alternatives include displaying all devices that have full or partial test coverage.
Test generation is facilitated by the Design Browser too. The ScanWorks Interconnect Test Generation engine has access through the Design Browser to the detailed design information that is used to build the board. This means that interconnect data can be extracted from the full database of design data. In addition, pin I/O information can be extracted from the full design database to determine whether each net can be tested safely with boundary scan.
A Communications Conduit
The Design Browser gives anyone in the organization the ability to dynamically interact with design data throughout a product’s entire lifecycle. For instance, engineers can trace signal information quickly or designers can participate in online design reviews via the Design Browser. Even the purchasing department can use the Design Browser to communicate the contents of an entire design to suppliers. Management might use it to monitor the progress of a design project.
With the Design Browser, board layouts or schematics can be browsed, queried and probed without the expense of a license for the complete computer-aided-engineering (CAE) system that generated the design data in the first place. Extensive electrical information or annotated comments can be associated with a design database and this information is available to anyone who has access to the Design Browser. Bill-of-materials, and test point or routing topologies can be output from the Design Browser to a spreadsheet to simplify communicating this type of information.
The ScanWorks Design Browser is compatible with all of the prominent file formats in the industry. As a result, it will accept inputs from practically any schematic capture or physical layout system.
