The Differences panel displays a hierarchical view of document differences.
The Differences panel is used to display the logical or physical differences found by the software's built-in Differences Comparator when comparing design documents. For example, when comparing the source document hierarchy (schematics) for a project against the PCB design document. The panel allows you to interactively explore the differences before the decision to create an Engineering Change Order (ECO) that will be used to synchronize the project documents.
To open the Differences panel, from a schematic document:
How the Differences panel is applied depends on whether the goal is to:
Comparison of project documents for logical differences is carried out through the Choose Documents To Compare dialog, activated by right-clicking on a project (or project document) in the Projects panel and selecting Show Differences from the associated context menu.
Right click on a project name and select Show Differences to open the Choose Documents To Compare dialog.
Typically, the PCB document would be compared against the source document hierarchy for the parent project to detect logical differences between the schematic design content and the PCB design content.
After clicking OK, if any differences exist between the nominated documents, the Differences between dialog will open. Information in the Differences panel will only appear after clicking the Explore Differences button in the Differences between dialog.
The Differences panel provides a convenient alternative to the Differences between dialog for browsing through detected document differences.
The Differences panel will only display the differences that are listed in the Differences between dialog. These, in turn, are determined by the selections made in the Comparator tab of the Project Options dialog (Project » Options).
This tab lists all of the comparison types, such as differences associated with Components, Nets and Parameters. Setting the Mode for each comparison category between Find Differences or Ignore Differences will determine if the Differences Comparator passes its results into the Differences between dialog.
Set up how the differences are detected and reported in the Project Options dialog.
The Differences panel displays the differences found between source documents in a tree-like structure, where the top-level folder displays the total number of differences detected. Sub-folders are then created for each specific comparison type that appears in the Differences between dialog. Each sub-folder lists the specific differences that have been found, which in turn are broken down further into objects on the documents that are responsible for creating those differences.
If the associated document is open (or open and hidden), clicking on an object entry in the panel will cross-probe to the object on the document.
The relevant editor will graphically highlight the entry as follows:
The graphical (physical) comparison of two versions of the same schematic or PCB document is basically carried out in the same way as for the logical comparison outlined above, but also makes use of the Advanced Mode in the Choose Documents To Compare dialog.
Perform a document physical comparison using the Show Differences command (Project panel right-click menu) to open the Choose Documents To Compare dialog then check the Advanced Mode box. With all project files now shown in the dialog, select the two variations of a document for comparison.
Selecting documents for physical comparison from the Choose Documents To Compare dialog in Advanced Mode.
Clicking OK will proceed with the graphical comparison and open the Differences between dialog as outlined previously. Click Explore Differences to open the interactive differences list in the Differences panel.
Detected physical differences hierarchy in the Differences panel.
The panel displays the differences found between the documents in a tree-like structure. The top-level folder displays the total number of differences detected. Entries are created for each type of difference, which in turn contains the specific references and the object (port, part, etc.) involved for each.
Selecting the object entry for a detected difference will highlight and zoom to the object in the editor workspace.
Interactive navigation in the Differences panel displays the object that created the difference as it is selected in the panel.
The relevant editor will graphically highlight the entry as follows:
