AND
The output of an AND function is only 1 if all inputs are 1, that is, when they are closed.
A block input that is not used (x) is assigned: x = 1.
A block input that is not used (x) is assigned: x = 1.

AND with edge evaluation
The output of an AND function with edge evaluation is only 1 if all inputs are 1 and at least
one input was 0 during the last cycle.
The output is set to 1 for the duration of one cycle and must be reset to 0 for the duration of
The output is set to 1 for the duration of one cycle and must be reset to 0 for the duration of
the next cycle before it can be set to 1 again.
A block input that is not used (x) is assigned: x = 1.
