Starting with the Allegro PCB Editor 16.6 release, we can compare two constraint databases and view the constraint differences. This provides an efficient opportunity for designers to determine the differences between 2 designs.Read on for more details
Generate a Constraint Difference Report
1. Open the Constraint Manager.2. Select File > Import > Constraints.3. The 'Import Constraints' dialog box is displayed. Select the 'Report Only' check-box.4. Choose the .dcf file to compare. This .dcf file is exported from a different database.5. Click 'Open' to create the report.The Constraint Difference Report is shown below:
In the same way you can also select File > Import > Technology File and open a .tcf file to view the Technology Difference Report.
View a Constraint Difference Report
The report can be opened in a built-in report viewer. This viewer consists of a toolbar and view window.Report Viewer Toolbar:
The table below describes the function of each tool button.Tools FunctionPrevious Selection shows previous view of the reportNext Selection shows next view of the reportExport report to HTML Export the report as an HTML pagePrint Preview Shows a printer-friendly view of the reportClose Window Closes the report viewer
Export Report as HTML
1. Select the 'Export report to HTML' button from the toolbar. The Export Report dialog box is displayed.2. Browse the directory to save the report.3. Provide a report folder.

Printing a Report
1. Select the 'Print Preview' button from the toolbar. The printer view is displayed for review.
2. Choose 'Send to printer' for printing the report.
Representing Constraint Differences
The Constraint Difference Report viewer is a two-frame, tree-view based representation.
1. By Tree-view shows a summary of the selected node in the tree-view:
2. By following Links, shows a summary of an object when selecting the object name link3. By previous and next show selections made forward and backward in the report selections
There are three viewing modes:1. Summary only (S) shows a description only with the number of changes
2. Differences only(D) shows Destination and Source constraints for each attribute. Unchanged layers are not shown.
3. All values(A) shows constraints at Destination and Source for all layers.
Please share your experiences using this new 16.6 capability.Jerry “GenPart” Grzenia
