Computer-implemented method for simulating an electrical circuit by means of a real-time platform

A computer-implemented method for simulating an electrical circuit via a real-time platform, the simulation of the electrical circuits taking place on the real-time platform under a real-time operating system based on a behavioral model in nodal form with an impedance matrix M or a topology-oriented behavioral model in a state space with matrices A, B, C, and D, at least one impedance matrix M describing the electrical circuit to be simulated or at least one set for the matrices A, B, C, and D describing the electrical circuit to be simulated is stored on the real-time platform for this purpose, the method comprising:

• executing the behavioral model for the electrical circuit on the real-time platform, the behavioral model having a controller that sets parameters of the simulation as a function of the current simulation and sends a calculation request regarding the calculation of the impedance matrix M or the matrices A, B, C, and D to a computer connected to the real-time platform when it is determined that no associated impedance matrix M or no associated matrices A, B, C, or D are stored on the real-time platform for a parameter value to be set;
• receiving the calculation request on the computer connected to the real-time platform and performing the requested calculation of the impedance matrix M or the matrices A, B, C, and D on the computer;
• transmitting the calculated impedance matrix M or the calculated matrices A, B, C, and D from the computer to the real-time platform;
• and
• using the impedance matrix M calculated on the computer or the matrices A, B, C, and D calculated on the computer in the simulation on the real-time platform.
