Presentation transcript:

A sequential logic circuit (a.k.a. state machine) consists of both combinational logic circuit(s) and memory devices (flip flops). The combinational circuits are used to supply the J&K inputs the correct data so that the memory units can progress from their current state to the desired next state at the next clock pulse. Designing sequential logic circuits requires several distinct steps. 1) Describe the circuit's function with a state diagram. 2) Design a' Next State' table for the state diagram. 3) Construct a 'Transition Table' from the Next State table 4) From the Next State table, use Karnaugh maps to design minimized combinational circuits to drive the JK inputs to your flip flops.
