加载中…set_clock_group参数详解

The is
the name given to the clock group.
The -group option
allows you to define the members of the clock group (i.e. clocks
with no timing relationship). You use
the –logically_exclusive and -physically_exclusive options
when one of multiple clock sources can be selected to drive a clock
tree (e.g. BUFGMUX or BUFGCTL). Such clocks are mutually exclusive
and cannot be present on the clock tree simultaneously, so we do
not want Vivado to analyze the relationship among these clocks.
The –asynchronous option
defines asynchronous clock paths.
