Method and apparatus for Laplace transform system simulation

An article of manufacture comprising a non-transitory computer-readable storage medium storing program instructions that when executed by at least one processor or at least one processor core of a computer system cause the computer system to simulate an integrated circuit design by performing operations comprising:

• identifying a relationship that describes behavior of the system in response to an input comprising at least one analog signal to the system that exhibits a first dynamic range, wherein the system includes one or more blocks of semiconductor components, and a dynamic range indicates an extent of variation among a plurality of multiplicative factors of respective elements in an expression for the system;
• enhancing computational accuracy of the computing system at least by reducing, with at least a normalization module stored at least partially in memory of the computing system, the first dynamic range into a second dynamic range at least by transforming, at multiple modules stored in a plurality of memory units of the computing system and coupled to one or more processing units of the computing system in accordance with semiconductor manufacturing requirements pertaining to functions of the system, the system with at least the relationship in multiple stages into a transformed system that exhibits the second dynamic range, wherein the second dynamic range is less than the first dynamic range;
• and
• determining the behavior of the system by using at least the transformed system exhibiting the second dynamic range.
