1.3 Creating an 8-bit Adder (10 marks) Review the Wire bundle section of the Logisim documentation and complete the following: 1. Start a new Logisim project and save it as add8.circ in your circuits directory. 2. Load add4.circ from your circuit library (This will allow you to insert 4-adder circuits). Add two 4- adders to the workspace. 3. Create two 8-bit wide input pins named arg1 and arg2. 4. Create a 1-bit wide output pin named cout. 5. Create an 8-bit wide output pin named sum. 6. Attach East-facing splitters to arg1 and arg2. Before adding these splitters, make sure the bit-width is 8 and the fan-out is 2. Make sure the fan wires are not blue. 7. Attach a West-facing splitter to sum. Its wires will be blue. 8. Implement the connections between the adders that will allow the two 4- adders to work together to perform the function of an 8-adder. 9. Connect the input of each adder (or half adder) to the corresponding wire of the splitter connected to arg1. 10. Repeat for arg2. 11. Test your circuit and construct your truth table.
