Combined Resources
Within each region, there are 22 distinct dedicated clocking resources
consisting of 16 global clock lines, four regional clock lines, and two fast
regional clock lines. Multiplexers are used with these clocks to form eight
bit busses to drive LAB row clocks, column IOE clocks, or row IOE clocks.
Another multiplexer is used at the LAB level to select two of the eight row
clocks to feed the LE registers within the LAB. See
This is a set of two multiplexers.
In addition to the FCLK pin inputs, there is also an input from the I/O interconnect.
