Abstract

A circuit for parametric testing of an integrated circuit includes an integrated circuit having a plurality of input buffers and a plurality of XOR gates. The plurality of XOR gates have a first input that is connected to an output of one of the input buffers and having a second input that is connected to an output of a preceding XOR gate to form an XOR logic tree.
