Figure 2–13. Global Clock Generation
Note to
(1) Any I/O pin can use a MultiTrack interconnect to route as a logic array-generated global clock signal.
The global clock network drives to individual LAB column signals, LAB column
clocks [3..0], that span an entire LAB column from the top to the bottom of the device.
Unused global clocks or control signals in a LAB column are turned off at the LAB
column clock buffers shown in
multiplexed down to two LAB clock signals and one LAB clear signal. Other control
signal types route from the global clock network into the LAB local interconnect. See
“LAB Control Signals” on page 2–5
