ABSTRACT:
A method of simulating a differential cascode voltage switch circuit (domino circuit) by replacing each switch-level logic tree by a three-section Boolean tree. In each section, a switch is replaced by an AND gate. The first and third section pass signals in one direction and the second section passes signals in the opposite directions. The three sections are interconnected end to end. Various faults can be simulated by holding selected internal signals at faulty values.
