Dedicated Routing
In addition to the global and local routing resources, dedi-
cated signals are available.

DS083 (v4.7) November 5, 2007
Product Specification
The double lines route signals to every first or second
block away in all four directions. Organized in a
staggered pattern, double lines can be driven only at
their endpoints. Double-line signals can be accessed
either at the endpoints or at the midpoint (one block
from the source).
The direct connect lines route signals to neighboring
blocks: vertically, horizontally, and diagonally.
The fast connect lines are the internal CLB local
interconnections from LUT outputs to LUT inputs.
There are eight global clock nets per quadrant. (See
Global Clock Multiplexer Buffers, page

Horizontal routing resources are provided for on-chip
3-state buses. Four partitionable bus lines are provided
per CLB row, permitting multiple buses within a row.
(See
Two dedicated carry-chain resources per slice column
(two per CLB column) propagate carry-chain MUXCY
output signals vertically to the adjacent slice. (See
CLB/Slice Configurations, page
One dedicated SOP chain per slice row (two per CLB
row) propagate ORCY output logic signals horizontally
to the adjacent slice. (See
One dedicated shift-chain per CLB connects the output
of LUTs in shift-register mode to the input of the next
LUT in shift-register mode (vertically) inside the CLB.
