In this timed lab, you will be creating a one-hot finite state machine in CircuitSim. This Finite State Machine will take in one 1-bit input, and it will output three 1-bit outputs. Diagrams and detailed instructions are provided below.
1 Instructions
Please make sure you have CircuitSim 1.7.4 or CircuitSim 1.8.0 downloaded on your computer. It can be found here.
1.1 State Transition Diagram
Figure 1: Transition diagram.
1.2 Restrictions
Your main register MUST be named ”stateReg”, and the input / output pins we have given you in the skeleton file must not be renamed. Do not add any additional input / output pins other than the ones we have given you. Do not rename the sub-circuit we have given you. If you have issues, check out the ”Common Errors” section below.
If you have any questions on what you may not use then assume you can’t use it and ask a TA.
You are only allowed to use the following components in CircuitSim:
• Basic logic gates (AND, OR, NOT)
• Registers (for this assignment, exactly ONE)
• Wires, splitters/joiners, tunnels, constants, plexers
