Tried to simulate PC_BIT Register using 16 DFFs (16 bit Register / Counter) for the ROM input addr in Tinkercad.
Although, luck was not on my side today. Probably my mistake was to do everything at once.
Considering 16 Bits take up a lot of gates for them which is impossible without many GATE ICs.
I will try it again but first simulating 1 bit at a time. Debugging this hot mess is impossible its more feasible to sart over.
