Draw the diagram of the FSM that can detect the sequence 1(01)*1, where * represents zero or more times. For example, the sequence can be 11, 1011, or 101011, etc.

The following diagram shows a Moore-machine based solution.

  1. Looks like it can be done in 4 states.
    Can you recheck my solution ?

    S0 = (in ==1’b1) ? S1:S0
    S1 = (in ==1’b1) ? S3:S2
    S2 = (in ==1’b1) ? S1:S0
    S3 = (in ==1’b1) ? S3:S2

    output = (state == S3)
