Simulate your design.Unit Design a bit addersubtractor that accepts two bits numbers, A and B andeither add them up A B or subtract them A B depending on a control signal ASwhen the control signal is perform ADD, otherwise if the signal is then performSUB The result will be stored in CUnit Design a bit ANDOR unit that accepts two bits numbers, A and B andeither AND them or OR them depending on a control signal AO when the controlsignal is perform AND, otherwise if the signal is then perform OR bitwise logicaloperation The result will be stored in CUnit Design three bit parallel registers to hold A B and C where C keeps theoutput of the ALU. The registers have a RW control signal that indicates that they arebeing written to or read from.Please provide photo of loogisim circuit
