Sequence 110

Design a sequential circuit with one binary input and one binary output. The output must be 1 at cycle $i$ when the inputs at cycles $i-2$ , $i-1$ and $i$ are 110, otherwise the output must be 0.

Specification

module find110(in, out, clk, rst);
    input in, clk, rst;
    output out;

Hint

The state machine can be implemented with 3 states.

Input

clk is the clock signal
rst is the synchronous reset signal.
in is the binary input.

Output

out is the output that behaves according to the specification.
