Question

Wanted to verify my answers for these:

1) The following Verilog snippet describes the functionality of:
always @ (enable or input)
if (enable)
output <= input
end

A) a d latch

a flip-flop

a not gate

D)a 4x1 multiplexor

___________________________________________________________________________________

2)

Input and output signals can be declared as signed

True

False

__________________________________________________________

3)

A testbench creates an instantiation of the module that we are testing.

True

False

A) a d latch

a flip-flop

a not gate

D)a 4x1 multiplexor

Explanation / Answer

Please follow the data :

1) As displayed in the code, the input/enable gets checked and the operation does continue which represents that of a NOT gate.
So the answer is "C) A NOT Gate".

2) Yes, a input and an output signal can be declared as signed.
If for the inputs is a signed signal and during the operation performed the result might be an signed signal even.
So the answer is "A) True".

3) Yes, A testbench creates an instantiation for the module that is feasible and is easy to perform the desired operations on the module, so that it is helpful for the testing.
So the answer is "A) True".

Hope this is helpful.
