Clock Regions
Virtex-5 clock trees are designed for low-skew and low-power operation. Any unused
branch is disconnected. The clock trees also manage the load/fanout when all the logic
resources are used.
All global clock lines and buffers are implemented differentially. This facilitates much
better duty cycles and common-mode noise rejection.
In the Virtex-5 architecture, the pin access of the global clock lines are not limited to the
logic resources clock pins. The global clock lines can access other pins in the CLBs without
using local interconnects. Applications requiring a very fast signal connection and large
load/fanout benefit from this architecture.
Virtex-5 devices improve the clocking distribution by the use of clock regions. Each clock
region can have up to 10 global clock domains. These 10 global clocks can be driven by any
combination of the 32 global clock buffers. The dimensions of a clock region are fixed to
20 CLBs tall (40 IOBs) and spanning half of the die
of the clock region, larger Virtex-5 devices can have more clock regions. As a result,
Virtex-5 devices can support many more multiple clock domains than previous FPGA
architectures.
logic resources in the center column (CMTs, IOBs, etc.) are located in the left clock regions.
The CMTs, if used, utilize the global clocks in the left regions as feedback lines. Up to four
CMTs can be in a specific region. If used in the same region, IDELAYCTRL uses another
global clock in that region. See
