12.1 FPGA Editor - "ERROR:FPGAEditor:271 - Cannot unplace component "xxx" -- It is locked in place with a "locate" constraint"


When I try to swap a component with another site in the FPGA Editor tool, I receive the following errors and warning:


ERROR:FPGAEditor:271 - Cannot unplace component "xxx" -- It is locked in place with a "locate" constraint.


WARNING:FPGAEditor:664 - Site "XXX_XmYn" does not meet the criteria of the LOCATE constraint of this comp.

ERROR:FPGAEditor:633 - Cannot place component "xxx" at site "XXX_XmYn"


How can I resolve the problem?


The error occurs because the placement of the original component is locked.

To unlock it, following these steps:

  1. Select the component, right click on it and select "Properties of Selected Items F2".
  2. Select the "Physical Constraints" Tab.
  3. If "Lock Placement" is checked, uncheck it.
  4. If "Lock Placement" is unchecked, change the value in the "Requirement" drop-down list to "None".
