+notimingchecks, +delay_mode_punit

I built n^2 and n counters with two 8-bit counters and have been testing with gate level simulation after synthesis and sta.

I tested with commands '+delay_mode_zero' and '-seq_udp_delay' and checked that graphs changed.
but no changes have been found with '+notimingchecks' and '+delay_mode_punit'.
How can I see changing points with that 2 commands?
