Figure shows PG networks for various 16-bit adders and Figure illustrates how these networks can be classified as the intersection of the l + f + t = 3 plane with the face of a cube. The plane also intersects one point inside the cube at (l, f, t) = (1, 1, 1) [Harris03]. Sketch the PG network for this 16-bit adder.
