Reevaluation and Updating of Footprints when Changes Are Made

You can update footprints in Capital Component Manager and Capital Logic Designer. Therefore the footprints on placed devices may need to be re-evaluated and updated.

Synchronizing logical design changes and performing a batch update of library parts is sufficient to update all library parts and footprint definitions. For details of how to perform these steps, see Synchronizing Changes in Capital Logic Designer Designs with the Capital Systems Integrator Design and Performing a Batch Update of Library Parts.

Note

Performing those steps does not prompt a re-evaluation of the “Assign Footprint to Device” constraint (if used). If required, the constraint can be re-evaluated by pressing Space Bar and entering Footprint.

When the system re-evaluates footprint data, it must synchronize any changes into the topological design. This can affect previously placed devices and therefore previously created wiring:

An affected device is not left with a pin mapping that does not match the footprint. The data defined in the footprint (which is some or all of the connectors, their part numbers and the device to pin to cavity mapping) are reflected in the topological design. Whenever possible, the device pin mapping is updated to match the new footprint data. If this cannot be done, then the device is left placed but may have one or more device pins unmapped.
Affected wiring is not left if there is a signal mismatch caused by a change of pin mapping. Whenever possible, existing wiring is moved together with the change in pin mapping. If this is not possible, the wiring may be deleted.
If a device is unplaced or wiring is deleted, a message displays in the Output Window (the tab depends on whether you have synchronized logical changes or performed a batch update of library parts).
When device pins are unmapped, the system maps all the pins associated with a connector, not just some of them. This is so that you can re-map the whole footprint in the Connector Map dialog box.
When you place multiple devices with footprints in the same slot, all footprint connectors mapped to the same slot connector must be compatible (that is, have the same part number).
