1.5.11. INPUT_TRANSITION_TIME

Specifies the input transition time. This assignment is used in Quartus to adjust the timing of the I/O buffers for all families that support AIOT. It is also used when generating the PrimeTime script that it is used by the HardCopy back end. This assignment gets converted as a set_input_transition SDC command. If the assignment does not exist, Quartus will generate a set_input_transition using 80% of VCCN * 1V/ns where VCCN depends on the I/O Standard used
