Tpd is the maximum acceptable input to non-registered output delay, that is, the time required for a signal
from an input pin to propagate through combinatorial logic and appear at an output pin.

Example usage:

quartus_fit one_wire --tpd=20.55ns

The format is "

The following table displays possible time units:

--tsu=

Option to specify the tsu time value.

Tsu is the maximum acceptable clock setup time for the input (data) pin. The setup time is the length of
time for which data that feeds a register via its data or enable input(s) must be present at an input pin
before the clock signal that clocks the register is asserted at the clock pin.

Example usage:

quartus_fit one_wire --tsu=7.55ns

The format is "
