machine using three process blocks. The Mealy state machine has one
input (ain) and one output (yout). The output yout is 1 if and only
if the total number of 1s received is divisible by 3 (hint: 0 is
inclusive, however, reset cycle(s) do not count as 0- see in
simulation waveform time=200). Use the testbench and verify the
model through a behavioral simulation. Use SW15 as the clock input,
SW0 as the ain input, the BTNU button as reset input to the circuit
and LED0 as the yout output. Go through the design flow, generate
the bitstream, and download it into the Nexys4 board. Verify the
functionality.
