The Edit Component Links dialog

Summary

The Edit Component Links dialog provides controls to check and control the status of the links between components in the schematic and PCB domains. When a component is placed on a schematic sheet, it is automatically given a unique ID. As a precursor to comparison, Altium Designer scans the source schematic and target PCB documents for linked components. These are components that have been previously synchronized with one another and share a unique ID. This dialog provides controls to manually match and link components between the two domains.

Access

The dialog is accessed in the following ways:

• Click Project » Component Links from the PCB Editor.

• After updating a document when one or more nets are not able to be matched between the PCB and schematic. For example, it appears after a net name has been changed on the PCB or schematic, but the net name has not been changed on the corresponding design document. 
• Click Manual Component Links in the Failed to Match Unique Identifiers dialog.

Options/Controls

• Un-Matched Components - the left-hand side of the dialog lists components that are currently unmatched. Two lists are used for unmatched components: on the source schematic documents (left) and those unmatched components on the target PCB document (right). Each component is listed in terms of its designator, footprint name, and comment.

• Matched Components - the right-hand side of the dialog lists all components that are currently matched. The region's two columns list the schematic components on the left and the PCB components on the right, with each entry consisting of designator, footprint name, and comment.

• Right arrow (match selected) - click to manually match the currently selected unmatched schematic component, with the currently selected unmatched PCB component. The entries will disappear from their respective Un-Matched Components lists, and a single entry for the two will be added to the Matched Components region.
• Left arrow (un-match selected) - click to 'un-match' the currently selected component entries in the Matched Components region. The entries will be removed from the region, and the constituent components added back to their respective Un-Matched Components region lists.
• Double arrow (un-match all) - click to 'un-match' all components currently listed in the Matched Components region. The entries will be removed from the region, and the constituent components added back to their respective Un-Matched Components region lists.
• Add Pairs Matched By - click to automatically match unmatched components in accordance with the selected options to the right. Matching can be attempted by selecting any combination of Designator, Comment, and Footprint. Successful matching will result in applicable entries disappearing from their respective Un-Matched Components list and a single entry for each linked couple being added to the Matched Components region.
• Perform Update - click to effect changes made to linking. If there are un-matched any components, a confirmation dialog will appear alerting you that some existing component associations will be broken by proceeding. To continue, click Yes. An information dialog will appear showing how many links were modified and/or how many links were removed.
