4‐bit counter rolls over to 0 (1111 -> 0000) and so CEO return to 0. So a 4‐bit FF rolls over (starts at 0) every 2^4 = 16 clocks. Now suppose you had a circuit that
Apr 07, 2011 · [Verilog] Gray Counter implementation. Hi, so i am learning Verilog and wanted to do some "generic" modules to use latter on bigger projects. Just finished a Gray Counter (based on a Binary Counter), it seems to behave properly (in both test bench and hardware), but i know there are always improvement opportunities.
