Each global clock multiplexer buffer can be driven either by
the clock pad to distribute a clock directly to the device, or
by the Digital Clock Manager (DCM), discussed in
Clock Manager (DCM), page
plexer buffer can also be driven by local interconnects. The
DCM has clock output(s) that can be connected to global
clock multiplexer buffer inputs, as shown in
Global clock buffers are used to distribute the clock to some
or all synchronous logic elements (such as registers in
CLBs and IOBs, and SelectRAM+ blocks.
Eight global clocks can be used in each quadrant of the
Virtex-II Pro device. Designers should consider the clock
distribution detail of the device prior to pin-locking and floor-
planning. (See the Virtex-II Pro Platform FPGA User
Guide.)
