Abstract
A method of determining values for a circuit over a cycle includes: specifying first-cycle values for the circuit in a first cycle, the first-cycle values including voltage or current values for the circuit and providing reference cyclic values for characterizing a cyclic behavior of the circuit in the first cycle with a reference cyclic dimension; determining, from the first-cycle values, path-following values for the circuit in a second cycle, wherein the path-following values include transient values for characterizing a transient behavior of the circuit and cyclic-correction values for characterizing the cyclic behavior of the circuit relative to the reference cyclic values from the first cycle, wherein a cyclic-correction dimension of the cyclic-correction values is less than the reference cyclic dimension; and saving at least some values based on the path-following values in the second cycle.
