The Inversion Algorithm is an event-driven algorithm, whose performance rivals or exceeds that of Levelized Compiled code simulation, even at activity rates of 50% or more. The Inversion Algorithm has several unique features, the most remarkable of which is the size of the run-time code. The basic Algorithm can be implemented using no more than a page of run-time code, although in practice it is more efficient to provide several different variations of the basic algorithm. The run-time code is independent of the circuit under test, so the algorithm can be implemented either as a compiled code or an interpreted simulator with little variation in performance. Because of the small size of the run-time code, the run-time portions of the Inversion Algorithm can be implemented in assembly language for peak efficiency, and still be retargeted for new platforms with little effort.
