How it works
Input 0 and 1 are the Input to the Full ADDER with CIN being connected to GND. Input 2 and 3 are connected to the XOR gate. Input 4 is connected to the D flip D input. Input 5 is connected to the INVERTER. Input 6 and 7 are connected to the NAND and AND gate. OUTPUT 0 is the SUM output of the FULL ADDER and OUTPUT 1 is the COUT. OUTPUT 2 is the XOR, OUTPUT 3 is the NAND, OUTPUT 4 is the AND, Output 5 is Q, Output 6 is Q_B and Output 7 is the INVERTER
How to test
Use the DIP switches to set the inputs of the gates according to the descripton. The 7 Segment Display can be used to see the outputs.
