Assigning logic to locations

Manually assigning logic is an optional methodology to help you improve the performance and density of your design.

You do not need to manually assign logic to particular locations in your design. However, should you have specific design requirements, ChipPlanner allows you to have maximum control over your design.

What do you want to do?

• Assign logic to specific locations

To assign logic to specific locations:

1. Select the logic in the Physical tab of the Hierarchy window or in an Active List.

2. Drag the logic to the desired location. As you drag, valid assignment locations are highlighted. To remove the assignment, from the Edit menu, choose Undo.

If the logic assignment is valid, the logic is assigned and locked. To save changes for this design session, commit your changes when exiting the MultiView Navigator.

To assign logic to multiple locations:

1. While holding down the CTRL or SHIFT key, select the logic in the order you want it placed.

2. From the Logic menu, choose Assign To Location.

3. One by one, select the desired locations. The macros are placed in the order selected.

To unassign logic from a location:

1. Select the logic.

2. From the Logic menu, choose Unassign From Location.

To unassign logic from multiple locations:

1. While holding down the CTRL or SHIFT key, select the logic you want to unassign.
