Abstract

In this paper it is shown how the idea of the BBD decomposition of large-scale nonlinear systems can be implemented in a parallel DC circuit simulation algorithm. Usually, the BBD nonlinear circuits decomposition was used together with the multi-level Newton-Raphson iterative process. We propose the simulation consisting in the circuit decomposition and the process parallelization on the single level only. This block-parallel approach may give a considerable profit in simulation time though it is strongly dependent on the system topology and, of course, on the processor type. The paper presents the architecture of the decomposition-based algorithm, explains details of its implementation, including two steps of the one level bypassing techniques and discusses a construction of the dedicated benchmarks for this simulation software.
