Problems solved by technology

This approach is extremely time-consuming, requires considerable expertise, and does not necessarily lead to a stable simulation, since in the test runs of the simulations used to assess the stability no possible specific switching states were realized at all, or all The test run described above was not executed long enough to exhibit unstable behavior because the error had not accumulated sufficiently in simulation time to be able to identify the instability without a doubt

Abstract

A computer-implemented method for simulation of an electrical circuit with circuit components by at least one computing unit includes mapping a coupling of the substrate representations in a couplingequation system for exchange of calculated coupling variables between the subcircuits. The method also includes calculating, in an evaluation step, at least one stability parameter on a basis of the coupling equation system, and deciding, in a selection step and depending on the at least one calculated stability parameter, whether the current separation of the electrical circuit into subcircuits will be used as the basis of the simulation. The method further includes performing, after a successful selection, the simulation of the electrical circuit by calculating the substrate space representations on the at least one computing unit.

Description

technical field [0001] The invention relates to a computer-implemented method for simulating a total circuit with circuit elements and which is mathematically described by a total state-space representation by means of at least one calculation unit, the total circuit In the separation step, the circuit is decomposed into at least two subcircuits by separating the circuit branches, wherein each subcircuit is described mathematically by a substate space representation, wherein the substate space represents the coupling via the separated circuit branches The variables are coupled to each other, and each subcircuit is computed by numerically solving the coupled substate space representation on at least one computational unit. Background technique [0002] The invention relates to the technical field of simulating circuits in real time in order to influence or test technical physical processes. Technical physical processes may involve, for example—in particular in automation tec...
