ECEN 248: Introduction to Digital System Design Department of Electrical Engineering Assignment #3 Due Thursday, October 1, 2009 1. [10 points.] Suppose that a k -input gate has a delay of k seconds, and an area of k units. This data is valid for AND, OR, NAND, NOR gates of any number of inputs, for XOR gates of up to 2 inputs, and for INV gates. What is the area and delay of a 12-input XOR function, implemented as a minimum SOP? What is the area and delay of a 12-input XOR function, implemented using 2-input XOR gates?
