TimeQuest Timing Analyzer Wizard

Any digital device has tSU,tH at its input registers & tCO at its output registers and are given in its data sheet. FPGA is no different but don't have them in data sheet because you can program them within some range.

In the classic timing analyser you enter them for fpga such that it matches the external device timing. In TimeQuest you enter the external device's timings directly in set_input_delay and set_output_delay as per given equations.

If you are designing some modules inside FPGA without being connected to outside(yet) then you don't need to enter these.

So in short it is your external devices that matter here.
