Modes for Processing Constraints: Overwrite and Changes Only

All constraints captured in schematic get transferred to PCB using the schematic to PCB create process.

You can transfer constraints using one of the following two options using the Update Layout

and Update Schematic dialog boxes:

• Overwrite

Use the Overwrite mode when you need to overwrite the constraints in schematic or in board file.

• Changes Only

Use the Changes Only mode if you need to merge concurrent constraint changes done in schematic and layout.
