State-Machine Analysis Steps Assumption: Starting point is a logic diagram 1a. Determine next-state excitation function F 1b. Determine output function G 2a. Construct state table For each state/input combination, determine the excitation value Using the characteristic equation, determine the corresponding next-state values b Construct output table 2b. Construct output table For each state/input combination, determine the output value (can be combined with state table) Lecture 13: 4 3. (Optional) Draw state diagram
