Abstract
A method of, and apparatus for, obtaining a representation of an electrical circuit (,) suitable for time-domain simulation. The electrical circuit comprises a physical structure (,), which is modelled using electromagnetic field analysis, and also comprises a remainder circuit (,) of circuit components which are interconnected with the physical structure. The electromagnetic field analysis is capable of generating at least a high-frequency equivalent circuit which is representative of the physical structure (,) and is valid at the operating frequency of the circuit but not at DC. The method comprises including a set of DC sources (E,to E,) to ensure that, in a time-domain simulation, improved DC bias conditions are provided for any non-linear components in the remainder circuit. The DC sources may be voltage sources in each interconnection, current sources between each interconnection and a zero voltage reference interconnection, or a combination of the two.
