When I run timing analysis on my design, I receive the following warning:
"WARNING:SpeedCalc:42 - Cannot find referenced model "bel_clkin_psclk_pulse_1".
This generally indicates that there is an inconsistency between versions of
the speed and device data files. Please check to ensure that the XILINX
environment variable is set correctly. If the MYXILINX variable is set, make
sure that it is pointing to patch files that are compatible with the version
of software that the XILINX variable points to."
What does this mean?
This message will be seen if you attempt to set the frequency of the DCM below 1 MHz.
This will be fixed in the next major software release.
