Implement a self$-$testing testbench to verify your CLA implementation.

$-$ Declare required inputs and outputs and instantiate the unit under test

$($UUT$).$

$-$ Use k $=4$ and n $=16.$

$-$ Test that your CLA correctly adds all values a$,$ b with a$,$ b $<mtext\; id="EditorElement\_15709668"></mtext><mn\; id="EditorElement\_15709669">3</mn><mn\; id="EditorElement\_15709670">0</mn><mn\; id="EditorElement\_15709671">0</mn>$ if C$\_$IN$=0.$

$-$ Test that your CLA adds values a$,$ b that are set to the maximum possible values,

correctly when C$\_$IN$=0.$ Note the carry$-$out of the CLA.

$-$ Also test that your CLA correctly adds values a$,$ b$,$ which are each set to the maximum possible values, when C$\_$IN$=0.$

are added correctly when C$\_$IN$=1.$

$-$ Testing all possible inputs is too time$-$consuming; the simulation would potentially take a very long time.

time.

$-$ Display an appropriate error message if the UUT works incorrectly.

Note: The code framework issues a warning "SIMULATION TOOK TOO LONG, STOPPING

NOW" if your testbench is too slow. In this case, your code probably

an infinite loop in your code.

Note: You can compile and start your testbench with the following command:

Windows: $./$sim$.$bat cla, otherwise: $./$sim$.$sh cla
