3.7.1 To assign logic using ChipEditor:

  1. Select the logic in the Unassigned list box.
  2. Drag the logic to the desired location in the ChipEditor window.

If the logic placement is valid, the logic is assigned. To remove the placement, from the Edit menu, choose Unassign.

Error messages in the status bar notify you about invalid placement attempts. Choose Extended Error Message from the Help menu for more details on a specific error message. If you want to ensure that the logic is not moved during layout, you must lock the logic assignment and commit your changes before exiting ChipEditor.

Note: Assigning logic to a location that already has logic unassigns the previously assigned logic, even if its assignment was locked.
