Compare component revisions

Modified by Susan Riege on May 11, 2019


The Compare component revisions dialog

Summary

The Compare component revisions dialog allows for the visual comparison of two revisions of the same or different items. Revisions of items of the following content types can be compared:

  • Component Item
  • Symbol Item
  • Footprint Item
  • Managed Schematic Sheet Item
  • Schematic Template Item
  • PCB Fabrication Data Item
  • PCB Assembly Data Item
  • PCB Project Design Item

Access

The dialog is accessed from the Explorer panel by browsing to the relevant folder, selecting the two Item-Revisions that you want to compare then right-clicking and choosing Operations » Compare from the context menu.

Options/Controls

  • Show unchanged - disable to leave only those elements that are not identical.
  • Grid - displays the parametric data for the compared items.
  • Footprint - displays a visual representation of the compared footprint. Click Compare to open the Compare components dialog to run a comparison of the two referenced footprints.
  • Symbol - displays a visual representation of the compared symbol. Click Compare to perform a graphical comparison; any differences that are detected will be listed in the Differences panel. The schematic library documents for the two revisions are opened within the workspace by displaying them side by side in the design editor window. Clicking on a top-level folder for a detected difference will highlight that difference on both documents simultaneously.
  • Identical/Not Identical  - displays green (Identical) or red (Not Identical) signifying the comparison results of the listed parameter:
    • Identical - signifies that no difference exists between the parameter value/footprint/symbol for the two compared Component Item revisions.
    • Not Identical - signifies that a difference has been detected in the parameter value/footprint/symbol between the two compared Component Item revisions
  • Compare - click to open the Compare components dialog to run a comparison of the two referenced footprints or symbols.
