Now, use LogicWorks to create a single $1-$bit slice of the arithmetic circuit. Attach binary switches and probes to the inputs and outputs of the slice, respectively, and test that to make sure that the slice is working correctly. Once the correct behaviour is confirmed, use the DevEditor to encapsulate the $1-$bit slice as a component.

Finally, connect four $1-$bit slices $($as illustrated in class$)$ together, along with the logic designed earlier for F$0,$ to form a complete $4-$bit arithmetic circuit.

Verify that your final circuit operates correctly by using the circuit to complete Table $2$ below. The teaching assistant will ask you to demonstrate other combinations of values and instructions at his discretion when grading.

Save your design in a file named Lab$6-$Part$1.$ Make sure to keep a back$-$up copy of your implementation, as you will need it during next week's lab to complete the design of the ALU.
