Latest Patents

Yanfei Gu holds a patent titled "Fast and accurate simulation for power delivery networks with integrated voltage regulators." This invention focuses on a hierarchical approach for simulating power delivery networks (PDNs) that incorporate integrated voltage regulators (VRMs). The patent describes a method that decouples the simulation of the PDN from that of the VRM/package through PDN macromodeling. The approach utilizes a SPICE-accurate simulation for the VRM using a non-linear solver, while employing a linear solver for the PDN, ensuring minimal interaction between the two. This innovative method includes the use of a Backward Euler method with a fixed time step, allowing for efficient communication of boundary currents and voltages between the solvers.
