are you saying 256 bit counter. This is huge. on 50MHz it will probably take thousands of years to finish to roll over, till doom's day

Hold on, probably millions of years !!!

each clk of 50 MHz = 1/50 microsec

microsec to maximum value of counter = 2^256*(1/50)

= that divided by (10^6 *60*60*24*365) in years, check on your calculator
