摘要：
This paper considers a complete power delivery network model of a multicore processing system, including per-core voltage regulation loops through Fully Integrated Voltage Regulators. Based on a nonlinear descriptor formulation of the system equations, we propose a transient solver based on a two-level Waveform Relaxation iteration. The convergence properties and the scalability of this solver when implemented on a parallel computing architecture are investigated. Numerical results show fast convergence and excellent scalability properties.
