Global Clock Multiplexer Buffers
Virtex-II devices have 16 clock input pins that can also be
used as regular user I/Os. Eight clock pads are on the top
edge of the device, in the middle of the array, and eight are
on the bottom edge, as illustrated in
Figure 39
.
The global clock multiplexer buffer represents the input to
dedicated low-skew clock tree distribution in Virtex-II
devices. Like the clock pads, eight global clock multiplexer
buffers are on the top edge of the device and eight are on
the bottom edge.
