Global Clock Buffer Primitives
The primitives in
Table 1-2: Global Clock Buffer Primitives
BUFGCTRL
The BUFGCTRL primitive shown in
clocks. All other global clock buffer primitives are derived from certain configurations of
BUFGCTRL. The ISE® software tools manage the configuration of all these primitives.
BUFGCTRL has four select lines, S0, S1, CE0, and CE1. It also has two additional control
lines, IGNORE0 and IGNORE1. These six control lines are used to control the input I0 and
I1.
X-Ref Target - Figure 1-1
Notes:
1. All primitives are derived from a software preset of BUFGCTRL.
2. This primitive replaces the BUFGMUX_VIRTEX4 primitive.
