Need help with circuit project

Here are the instructions


Design a single sequence detector that is able to detect the sequences 010, 101, and 111 with overlap.

Design Constraint: Use only type D Flip-Flops and discrete gates and/or multiplexers.
Your choices: State assignment and use of Moore or Mealy state machines.
1. Provide a state table and state diagram.

2. Synthetize a circuit that detects the requested sequences.

3. Illustrate the iterative processes, or trial and error process or any process used, by which you
arrived at the selected circuit that best fulfills the design requirements and constraints.

4. Sketch your final and complete logic circuit.

5. Use Logisim to run a simulation and verify that your design works as intended.

6. Turn in a formal technical report.


I already made the circuit on logisim but im not sure how to make the state diagram and state table... can anyone assist me on this?

I am not sure it is possible to get state diagram in logisim.
You can create it manually as a description of your design. Look at: http://en.wikipedia.org/wiki/State_diagram for more ideas on the diagram and at: http://en.wikipedia.org/wiki/State_transition_table for table.
I guess there is not much difference between them though.
