# No need for any asynchronous clock groups between bus_clk and the recovered clocks,
# because bus_clk already has a blanket asynchronous constraint from the top level XDC.
# Remove analysis between the xge_clk and the recovered clocks from the MGT PHYs,
# since they cannot be related to one another with any known phase or period.
