How do you want to use
the ALTCLKCTRL
For global clock, or
For external path
Specify the ALTCLKCTRL buffering mode. You can
select from the following modes:
• For global clock—Allows a clock signal to reach all
parts of the chip with the same amount of skew; you
can select input port
clkselect
to switch between
the four clock inputs.
• For external path—Represents the clock path from
the outputs of the PLL to the dedicated clock output
pins; only one clock output is accepted.
How many clock inputs
would you like?
1, 2, 3, or 4
Specify the number of input clock sources for the clock
control block. You can specify up to four clock inputs.
You can change the number of clock inputs only if you
choose For global clock option.
Create ‘ena’ port to
enable or disable the
clock network driven by
this buffer
On or Off
