to get 1Hz from 50MHz is very simple but depends on whether you want one 50% duy cycle 1Hz pulse or just one pulse of 50MHz period every 1 second.

all you need is one bit signal that goes high or low.

for 50% duty cycle on the 50MHz counter:

if count is at first half 50M then raise the signal else lower it

if you want one pulse at 50MHz period only then:

at any one chosen count value raise the signal else lower it.
