Project Options - Comparator Tab

Parent page: WorkspaceManager Dialogs

The Comparator tab of the Options for Project dialog

SUMMARY

The Comparator tab of the Options for Project dialog enables you to define which types of differences to find and which to ignore when comparing documents. For each possible comparison, you can either choose to find or ignore differences using the associated drop-down in the Mode column. You can set up to find differences with components, nets, parameters, and physical objects, as required. Any differences found when documents in a project are compared will appear in the Messages window when compiling.

ACCESS

This dialog is one of multiple tabs available when configuring the options for a project and is accessed from within the Options for Project dialog. In the Options for Project dialog, click the Comparator tab. To access the Options for Project dialog:

• From the PCB or schematic editor, click Home | Project |  » Options.
• From the PCB or schematic editor, click Project | Content | .

OPTIONS/CONTROLS

This dialog is divided into two main regions:

• The upper region, titled Comparison Type Description/Mode, lists the description and comparison mode of each available comparison type.
• The lower region, titled Object Matching Criteria, is used to define the matching criteria for Net, Net Class, Component Class, and Differential Pair.

Comparison Type Description/Mode

• Comparison Type Description - this region lists the descriptions of each available comparison type within the project. Use the scroll bar on the far right to scroll to Differences Associated with Components, Differences Associated with Nets, Differences Associated with Parameters, and Differences Associated with Physical in order to view/change comparison modes within each area.
• Mode - click on an entry to change comparison mode in the drop-down:
  • Find Differences - select this option to find differences within that comparison type.
  • Find Differences (Case Sensitive) - select this option to find differences paying attention to case.
  • Find Differences (Case Insensitive) - select this option to find differences without regard to case.
  • Ignore Differences - select this option to ignore any differences within that comparison type (no comparison will be done for that comparison type).

Object Matching Criteria

• Object Type - list of types of objects such as Net, Net Class, Component Class, and Differential Pair.
• Min Match % - enter desired minimum match percentage value or click in the right side of the column then use up and down arrow keys to increase or decrease value.
• Min Matched Members - enter desired minimum matched members or click in the right side of the column then use up and down arrow keys to increase or decrease value.
• Use Name Matching - click entry or use drop-down to select After member matching or Never.
• Show Manual Matching Dialog - click entry or use drop-down to select For unmatched objects or Never.

Additional Controls

• Ignore Rules Defined in PCB Only - enable this option to ignore rules defined in the PCB only within the design project. For instance, when you do an Engineering Change Order, changes can be applied from schematic to PCB and if this option is enabled, the rules in PCB only are ignored. If there are no corresponding rules in schematic sheets of the same project, the comparator will not try to add new rules.

• Set To Installation Defaults - click this button to return all entries to their default state.
  • Defaults are as follows:
    • Mode = Find Differences or Find Differences (Case Insensitive) where appropriate
    • Min Match % = 75
    • Min Matched Members = 3
    • Use Name Matching = After member matching
    • Show Manual Matching Dialog = For unmatched objects
