Regional Clock Nets
BUFGCTRL VHDL and Verilog Templates
R
VHDL Template
In addition to global clock trees and nets, Virtex-4 devices contain regional clock nets.
These clock trees are also designed for low-skew and low-power operation. Unused
branches are disconnected. The clock trees also manage the load/fanout when all the logic
resources are used.
Regional clock nets do not propagate throughout the whole Virtex-4 device. Instead, they
are limited to only one clock region. One clock region contains two independent regional
clock nets.
To access regional clock nets, BUFRs must be instantiated. A BUFR can drive regional
clocks in up to two adjacent clock regions
can only access one adjacent region; below or above respectively.
The VHDL and Verilog code follows for all clocking resource primitives.
The following examples illustrate the instantiation of the BUFGCTRL module in VHDL
and Verilog.
