Tech Tip: Setting Clearance Classes in CR-8000 Design Gateway

When a design requires specific minimum spacing between net classes, these clearance classes can easily be created and assigned in CR-8000 Design Gateway.

You can create clearance classes in CR-8000 Design Gateway, and forward annotate them to CR-8000 Design Force. They can be assigned spacing rules from design rule stacks in your library.

In the CR-8000 Design Gateway constraint browser, select the Utility pulldown, then edit Clearance Class. Enter a new Clearance Class Name.  Assign the design rule stack to each clearance class combination. Finally, Forward Annotate to your board.
