This lab will be done using Logicly

You$$re going to create a circuit which can take

two four$-$bit Nibble registers, ADD them, AND them, or OR them. Also, it can take $-$THE A INPUT ALONE$-,$

and NOT it$.$ So your circuit will still have two four$-$bit Nibble Inputs, and a four$-$bit Nibble output, just like

the previous lab. Your OUTPUT will also be going to four LAMPS $($as well as the $4-$Bit Display from last

time$),$ so that you can properly see the results of AND, OR$,$ and NOT.

However, you$$ll have two additional inputs, the CONTROL inputs. These two inputs will be

dictating WHAT your circuit should do:

$00$ NOT the A value

$01$ AND the A and B values together

$10$ OR the A and B values together

$11$ Perform ADDITION on the A and B values.

Create integrated circuits for the AND, OR$,$ and NOT portions of the circuit, just as you previously

did for the addition lab. So for example:

$1011$ AND $0110$ would result in $0010.$

$1011$ OR $0110$ would result in $1111.$

$0010$ NOT would result in $1101($Note that for NOT it doesn$$t matter WHAT the B inputs are, it won$$t use

them$)$

The MULTIPLEXOR we worked on in class is the prime means of creating this simplistically and

efficiently. Make an Integrated Circuit of a Multiplexor. First build one that can take SIX inputs $($two

control, four input bits$),$ and select between them to make just ONE output. Make an IC of that single

Multiplexor, then combine four of them together to make a Nibble multiplexor.

Capture screenshots of the shown inputs, and the resulting outputs.

$1$: Input: A: $1101,$ B: $0111,$ CONTROL: $01$

$2$: Input: A: $0001,$ B: $0111,$ CONTROL: $00$

$3$: Input: A: $0110,$ B: $1000,$ CONTROL: $10$

$4$: Input: A: $0101,$ B: $0011,$ CONTROL: $11$

$5$: Input: A: $1011,$ B: $1110,$ CONTROL: $11$

Please make sure you submit a screenshot of your completed circuit, and CLEARLY STATE the results of

each configuration of inputs
