Number of DCMs and locations of these DCM varies for different device densities.
The left and right DCMs are only in the XC3S1200E and XC3S1600E. The XC3S100E has only two DCMs, one on the top right
and one on the bottom right of the die.

The connections for the bottom-edge BUFGMUX elements
is similar to the top-edge connections.
On the left and right edges, only two clock inputs feed each
pair of BUFGMUX elements.
