By running simulations in parallel on multi-core processors, simulation time can be significantly decreased. This thesis investigates the possibil-ities of making simulation models parallel by using independent distrib-uted solvers. Sub-components are separated numerically by transmission line elements. An algorithm for automatically distributing the workload with good load balancing is demonstrated. Synchronization between sim-ulation threads is maintained by a simsim-ulation routine using barrier locks. Measurements confirm that almost linear speed-up can be achieved for large models. The method is less useful for smaller models due to over-head costs. Experiments that confirm the feasibility on real-time applica-tions are also presented.
