ID:11898 Input Transition Time "<rise_or_fall>" assignment of "<user specified input transition time>" ps on "<pin name>" is ignored because the value is too small. The minimum value of input transition time for the current I/O standard is "<minimum input transition time>" ps. Using the default input transition time, "<default input transition time>" ps, for this I/O standard.

CAUSE: You have specified an Input Transition Time timing assignment on the specified pin. This value is too small. Therefore the input transition time value is ignored and a default input transition time based on the I/O standard is used instead.

ACTION: Specify the input transition time to be greater than the minimum value for the particular I/O standard listed in the warning message.
