GPU-Powered Harmonic Balance Analysis in Radio Frequency Circuit Simulation

Radio frequency (RF) circuit simulation usually has much larger equation scale than that of the corresponding SPICE model, which poses an immense challenge to meet designer's simulation time requirement with traditional CPU platform. In this paper, we report a GPU-powered harmonic analysis algorithm to address harmonic balance calculation in RF simulation. The major bottlenecks in harmonic balance analysis are presented and solved on GPU platform. Significant performance improvement has been achieved for a large-scale circuit.
