15.7.8 Editing Regions

After creating regions, with the exception of LocalClock regions, you can rename, delete, move, and re-size them. LocalClock regions can only be renamed or deleted.

Regions must have unique names. Two regions cannot have the same name.

To change the name of a region:

  1. In the Hierarchy window, click the Regions tab.
  2. Select the region with the name you want to change.
  3. From the Region menu, choose Properties.
  4. In the Properties dialog box, type the new region name over the existing one.
Note: You can also right-click a region, choose Properties, and type a new region name in the Properties dialog box.

To delete a region:

  • Right-click the region, and chose Delete.

To move a region:

  • Select the region and drag it to a new location.
Note: You cannot move the region if a macro assigned to the region is locked.

To re-size a region:

  1. Select the region.
  2. Grab and drag the sides and corners to re-size the region. You cannot resize a region smaller than the logic it already contains.

To merge a region:

  1. In the Hierarchy window, click the Regions tab.
  2. Select the regions you want to merge.
  3. Right-click any selected region and choose Merge.

The merge operation:

  1. Creates a new region with rectangles of all selected regions
  2. Assigns logic and nets that were assigned to the selected region to the new region
  3. Removes the selected regions
