Abstract
A method of providing critical circuits in a library of circuits, whereby such critical circuits allows designers to apply modifications to them in a controlled manner such that the changes are easy to implement and virtually guaranteed to be correct. The invention comprises a method of performing limited modifications to such critical circuits to alter its characteristics in a controlled manner, and thereafter checking the resulting modified circuit with a circuit simulator for conformance to predetermined specifications that have been assembled for this library critical circuit.
