Design Procedure 1. Determine the required number of inputs and outputs and assign variables to them. 2. Derive the truth table that defines the required relationship between inputs and outputs. 3. Obtain and simplify the Boolean function (K- maps, algebraic manipulation, CAD tools, …). ). Consider any design constraints (area, delay, power, available libraries, etc). 4. Draw the logic diagram. 5. Verify the correctness of the design.
Design Example Design a combinational circuit with 4 inputs that generates a 1 when the # of 1s equals the # of 0s. Use only 2-input 2 input NOR gates …
