Why do we need to specify reconfigurable modules beforehand? (partial reconfiguration)

Hi, I don't understand why we need to specify what should be cpuEngine, usbEngine0, and usbEngine1 when we create configuration in the figure above.(It is from ug909) Intuitively, the most efficient way is implementing static part first, and all the possible reconfigurable modules separately. Then, combine pre-implemented modules with static part so that all we need to do is stitching pre-implemented parts together.

 

If we have to specify reconfigurable modules beforehand, all we save is the time spent on placing/routing static part. I don't understand why there should be a coupling among cpuEngine, usbEngine0, and usbEngine1.

Sorry, never mind. Just realized that all the partial bitstreams for different physical locations are generated with the full bitstream.
