Notes to
(1) C4 and C12 interconnects can drive R4 interconnects.
(2) This pattern is repeated for every LAB in the LAB row.

interconnect. For R4 interconnects that drive to the right, the primary LAB and right
neighbor can drive to the interconnect. For R4 interconnects that drive to the left, the
primary LAB and its left neighbor can drive the interconnect. R4 interconnects can
drive other R4 interconnects to extend the range of LABs they drive. R4 interconnects
can also drive C4 and C12 (column interconnects) for connections from one row to
another. Additionally, R4 interconnects can drive R20 interconnects.
R20 row interconnects span 20 LABs and provide the fastest resource for row
connections between distant LABs, TriMatrix memory, DSP blocks, and row IOEs. R20
row interconnects drive LAB local interconnects via R4 and C4 interconnects. R20
interconnects can drive R20, R4, C12, and C4 interconnects.
The column interconnect operates similarly to the row interconnect. It vertically
routes signals to and from LABs, TriMatrix memory, DSP blocks, and IOEs. Each
column of LABs is served by a dedicated column interconnect. These column
interconnect resources include:
