Project Options - ECO Generation

Parent page: WorkspaceManager Dialogs

The ECO Generation tab of the Options for PCB Project dialog


This tab of the Options for PCB Project dialog enables you to configure which modification types can be included when generating an Engineering Change Order (ECO) based on differences found by the Comparator.

Configuration of modification types on this tab should be performed in conjunction with configuration of the comparison types on the Comparator tab of the Options for PCB Project dialog.


This is one of multiple tabs available when configuring the options for a project – accessed from within the Options for PCB Project dialog. This dialog is accessed by:

  • Clicking Project | Content | from the main menus in the Schematic Editor or the PCB Editor.
  • Right-clicking on the entry for the project itself in the Projects panel then choosing Project Options from the context menu.


Modifications List

This list presents all possible modifications that can be made through an Engineering Change Order when synchronizing the source schematic documents with the PCB design document. Modifications themselves are gathered into the following categories:

  • Modifications Associated with Components
  • Modifications Associated with Nets
  • Modifications Associated with Parameters

Each specific modification type is presented with the following fields:

  • Modification Type Description - a short description of the type of modification (the action to be taken by the Synchronizer).
  • Mode - use this field to control whether the modification type is included in any generated ECO or not. Use the drop-down to choose from the following:
    •  - include the modification type in a generated ECO.
    •  - exclude the modification type from a generated ECO.
If a modification type has its Mode set to Ignore Differences, any design update that results in an action being of that modification type will not be transferred to the Engineering Change Order dialog when the ECO is created. The modification action will also be excluded from the ECO if the modification type has its Mode set to Generate Change Orders but the relevant source comparison type is set to Ignore Differences.

Right-Click Menu

The following command is available from the right-click context menu for the tab:

  • Report - use this command to generate a report of the currently configured modification modes. The Report Preview dialog will open with the report already loaded. Use this dialog to inspect the report using various page/zoom controls before ultimately exporting it to file or printing it.

Additional Options

  • Push Component Designator Changes to Annotation File (if any) – check to include component designator changes in the annotation file.
  • Set To Installation Defaults - click this button to return the Mode entries for all modification types to their default settings.
