Information messages regarding clock uncertainty may be seen in some UniPHY IP applications.
Info (332171): The following clock uncertainty values are less than the recommended values that would be applied by the derive_clock_uncertainty command
Info (332172): Setup clock transfer from mem_cq_n (Rise) to if0|pll0|pll_afi_clk (Rise) has uncertainty 0.000 that is less than the recommended uncertainty 0.090
The reason for these messages is that in this particular case, the clock uncertainties are intentionally zero-ed out because they are already included elsewhere in the timing analyis.
It is recommended to search for the affected clock in the UniPHY IP SDC file and verify that statements are observed of the type :
# Clock Uncertainty is accounted for by the ...pathjitter parameters
set_clock_uncertainty -from [ get_clocks ] 0
set_clock_uncertainty -to [ get_clocks ] 0
These Info messages can be safely ignored.
