M1 PERIOD placed on net between PAD and IBUF not analyzed
Problem Description:
Urgency: standard
General Description:
For the following arrangement:
Solution 1:
Like the TNM, the PERIOD constraint should also be placed on the output of an IBUF:
NET clock PERIOD = 10 ns;
A PERIOD constraint may be placed on the net between the IPAD
and BUFG; the above restriction only applies to IPAD to IBUF
connections.
