Partial Reconfiguration - ERROR:Place:293 - The following 2 components are required to be placed in a specific relative placement form

Description

I am receiving an error message in my PR design similar to the following:
 

ERROR:Place:293 - The following 2 components are required to be placed in a specific relative placement form.
The required relative coordinates in the RPM grid (that can be seen in the FPGA Editor) are shown in brackets next to the component names.
Due to placement constraints it is impossible to place the components in the required form.
LUT <>/<>/xxx  (0, 0)
LUT <>/<>/xx (0, 0)


How can 2 BELs (components) have the same names and be placed in the same BEL?

Solution

This problem happens when the PR module has defined a Pblock which covers most of the device. 

In this situation, the Static logic might not find any available location for its logic and will generate this error message.

 
The solution is to modify the size of the Area Groups so that all of the logic can be accommodated.
