Purpose:
Document CEUSEDMUX, SRUSEDMUX muxes

Algorithm:

Results:

CEUSEDMUX: whether clock enable (CE) is used or clock always on
0: always on
1: controlled
CLB.SLICE_X0.CEUSEDMUX 00_39
CLB.SLICE_X1.CEUSEDMUX <0 candidates>


SRUSEDMUX: whether FF can be reset or simply uses D value
(How used when SR?)
0: never reset
1: controlled
CLB.SLICE_X0.SRUSEDMUX 00_35
CLB.SLICE_X1.SRUSEDMUX <0 candidates>
