Must have experience in Intel Quartus Prime

Develop a 4-bit Adder using Quartus Prime with graphical design files. a. Name your top-level design “adder4”. b. Create a file “[login to view URL]”, build a half adder (inputs A, B, outputs S, Co) and create a symbol for it c. Create a file “[login to view URL]”, build it using two halfadders (from part b) and an OR gate, and create a symbol for it. (inputs A, B, Cin, Outputs S and Co). d. Create a file “[login to view URL]”, and build a 4-bit adder using 4 fulladder blocks. Your inputs and output will be 4-bit busses A, B and S and as well as the single-wire output Cout. Recall that to specify a single wire from a bus, use square brackets, such as A[2]. Note: Connect the CarryIn of the first bit to the symbol GND. e. Compile your project and fix any errors. f. Create a vwf simulator file and simulate your 4-bit adder: i. Insert the busses A, B and S (listed as “groups” in the node finder) as well as the node Cout. ii. Set your simulator with a step size of 1 us and an end time of 16 us. iii. Set input A to count from 0000 to 1111 by right-clicking, choosing select entire waveform , then choosing value, count, and increment by 1 every 1 us iv. Set input B to be a constant value equal to 9. Do this just like in step iii, but choose “arbitrary value” instead of “count value”. g. Run the simulation and confirm that your adder adds the values correctly. h. Turn in four screen shots pasted into a MS-Word file, each cropped to show only the relevant portions. i. [login to view URL] ii. [login to view URL] iii. [login to view URL] iv. [login to view URL] showing correct simulated results. (I would need the file as well) Alternative to simulation If you cannot get the simulator to work, you may instead program the project to the DE0-CV board. Use switches 9,8,7,6 for input A and switches 5,4,3,2 for input B. Use LEDs 9,8,7,6 for the sum and LED 4 for the CarryOut. Submit images of your board showing input combinations of 0011 + 1000, 1001 + 0001, 0101 + 1100 and 0010 + 0100. Modify your 4-bit adder to become a 4-bit adder/subtractor (see slide adders- 8). Your adder/subtractor has an additional input signal, subtract. If subtract = 0, the circuit adds A + B. If subtract = 1, the circuit subtracts A – B. Simulate the operation as above, but with the subtract signal low for the first half and high for the second half. (I would need the file as well)
