37 derive the state table and state diagram for the sequential circuit
The state transition table and diagram above contain the same information about the circuit. In the following, we analyze several synchronous sequential circuits by deriving their state transition table and diagram. These circuits are sequential building blocks for the design of larger sequential circuits. Derive state transition and output logic equations by inspection assuming a one-hot encoding. Implement only the state transition logic and output logic (the combinational logic portion) for this state machine. (The testbench will test with non-one hot inputs to make sure you're not trying to do something more complicated).
A state table can be constructed for a state, a state transition, or an entire paragraph. An STT is a three-part table consisting of (1) preconditions and their Boolean value assignments, (2) the set of state transitions achieved by satisfying preconditions, and (3) the set of actions taken upon satisfaction of the transition preconditions.

Derive the state table and state diagram for the sequential circuit. Transition Table Transition table is useful to analyze an asynchronous circuit from the circuit diagram Procedure to obtain transition table: 1. Determine all feedback loops in the circuits 2. Mark the input (y i) and output (Y i) of each feedback loop 3. Derive the Boolean functions of all Y’s 4. Plot each Y function in a map and combine all The following is the state transition table for a Moore state machine with one input, one output, and four states.
