The invention provides a hysteresis loop determination method for an inductance element of an integrated circuit power supply system. The hysteresis loop determination method comprises the following steps: applying a magnetic field to a magnetic core of the inductance element of the integrated circuit power supply system; under the action of the magnetic field, collecting multiple feature points of a hysteresis loop of the magnetic core, wherein the hysteresis loop represents the change relation between the magnetic field intensity acting on the magnetic core and the magnetic induction intensity of the magnetic core; and determining parameters for fitting an S curve of the hysteresis loop according to the plurality of feature points to obtain an equation of the hysteresis loop. According to the method and device, only a small number of feature points need to be collected when the hysteresis loop is determined, the situation that a large number of magnetic field intensity values and magnetic induction intensity values need to be collected when the hysteresis loop of the inductance element is determined in a traditional mode is avoided, a convenient and accurate way is provided for determining the hysteresis loop of the inductance element, and the measurement cost is reduced.
Description
technical field [0001] The present application relates to the technical field of integrated circuits, in particular to a method and device for determining a hysteresis loop of an inductance element in an integrated circuit power supply system. Background technique [0002] The power integrity analysis of integrated circuits plays a very important role in integrated circuit design. Studies have shown that a large part of the energy loss of the system-level integrated circuit power system comes from the inductance components that perform voltage conversion in the power system. Therefore, the inductance loss of the system-level integrated circuit power system is studied, and the energy conversion is reduced as much as possible through the optimization design method. Inductive losses in the process are of great significance in the power system optimization of system-level integrated circuits. [0003] Due to the nonlinear characteristics of the inductance loss, its calculation ...
