Assigning pins

Use PinEditor to make and edit I/O macro pin assignments. Edits you make in PinEditor are permanent, provided they are locked and have been committed.

To assign an I/O macro to a pin:

1. Select the macro name in the Unassigned list box. The macro is simultaneously selected in the I/O Attribute Editor.

2. Assign the selected macro to a pin location using any one of these methods:

3. Drag the selected macro name from the Unassigned list box to the pin location in the Package window. Valid pin locations are highlighted in the Package Window.

4. From the Edit menu, choose Assign to invoke Assign mode. Then, select the pin location in the Package window.

5. Click the Assign toolbar button to invoke Assign mode, and then select the pin location in the Package window.

6. If you know the specific pin location, enter the pin assignment in the Pin# cell or select a valid placement from the drop-down menu.

If the location is a valid one, the macro is assigned and automatically locked. The status bar displays information about invalid assignments. Choose Extended Error Messages from the Help menu for more information about specific error messages.

Note: If you assign a macro to a pin that has already been assigned a macro, the previously assigned macro becomes unassigned if it was not locked.
