And Gate

Abstraction and Implementation of And Gate in Hardware Design Language and Java™.

And Gate

The And function returns 1 (true) only when both of the inputs are 1 (true).

Implementation of And Gate in HDL

And Gate can be implemented in two ways:

• And Gate can be implemented using two Nand Gates - one Nand Gate for both inputs to produce some output, which is connected to either inputs of Another Nand Gate.

• You can observe that the second Nand Gate can be replaced with a Not Gate of single input which is the output of First Nand Gate.

Implementation of And Gate from Nand Gates

CHIP And {
    IN a, b;
    OUT out;

    PARTS:
    Nand(a=a, b=b, c=notout);
    Not(in=notout, out=out);
}

Implementation of And Gate in Java™

Similar to the Implementation in HDL

package CombChips;

class And_Gate extends Not_Gate {

    protected static int And(int a, int b) {
        return Not(Nand(a, b));
    }
}
