Design Changes Wizard

Designs go through updates and changes throughout the development process and into deployment. The Diagnostic Profiler can import updated EDIF netlists and merge the updates into existing project data that you have in process or had already completed. This feature of the Diagnostic Profiler is key to employing a true concurrent engineering approach: diagnostics capability can evolve concurrent with design. Without this capability, one would have to wait until after design was completed to initiate diagnostics development.

Design changes and updates are automatically incorporated merged into existing Diagnostic Profiler project data using the Import an EDIF Netlist tool. Choose the Update tab from the Import EDIF tool's dialogue box.

After EDIF translation processing is complete, you can use the Design Changes Wizard to analyze the impact of specific design changes on your tests that have already been mapped.

NOTE: this process will only work if the component names of previously defined parts remain essentially unchanged. In other words, if all component names have changed, then the updates will be too extreme for the update process to be effective.

Design changes include deleting components, adding components, modifying components, replacing components, modifying wiring and interconnectivity. These design changes have impacts on test coverage. For these areas, the Design Changes Wizard provides a summary of these changes and then gives you the capability to step through each design change that impacts a test that had previously been defined.

To use the Design Changes Wizard,

1. Import the updated EDIF file using the Update option from the Import an EDIF Netlist tool.

2. After the EDIF file update processing is complete, highlight the Design Changes Wizard tool from the tool list on the Import Design tab.
 
3. Press Use Tool

or

Double Click on Design Changes Wizard in the tool list.

The Design Changes Wizard summary screen will appear displaying a summary of the design changes.

From the Design Changes Wizard, you can:

1. View a list of new parts added to the design

2. View a list of parts deleted from the design

3. View impact of deleted parts or faults on previously defined measurements. (Where some or all covered faults have been deleted from a measurement)

4. View fault locations that are newly reachable from existing measurements

5. View fault locations that are newly unreachable from existing measurements

6. View new parts that are unreachable by existing measurements.

7. View new parts that are newly reachable by existing measurements.

Where appropriate, the Design Changes Wizard will step you through each measurement to modify coverage as required.
