A method includes obtaining a first waveform representing an output characteristic with respect to time of a switched-mode power supply. The method further includes removing a high frequency component from the first waveform to generate a modified waveform and determining a stable value of the modified waveform. The method further includes determining an operating parameter of the switched-mode power supply based on the modified waveform, the stable value, or a combination thereof. The one or parameter includes an overshoot value associated with the switched-mode power supply, an undershoot value associated with the switched-mode power supply, or a settling time associated with the switched-mode power supply. The method further includes outputting an indication of the parameter.

Determination of one or more operating parameters for a switched-mode power supply

A method includes receiving a circuit design including a plurality of components associated with a plurality of component parameters. The method further includes adjusting a value of a particular component parameter of the plurality of component parameters based on a tolerance to generate a modified plurality of component parameters. The method further includes determining, based on inputting the modified plurality of component parameters into a circuit calculator, that an operating value of the circuit design is sensitive to the particular component parameter. The method further includes selecting a simulation of the circuit design to perform based on the particular component parameter. The method further includes performing the simulation to determine whether the circuit design supports one or more design limits.

Simulation and analysis of circuit designs

Over the years, parallel processing has become increasingly common. Conventional circuit simulators have not taken full advantage of these developments, however. Here, a circuit simulator and system are provided that partitions circuit matrices to allow for more efficient parallel processing to take place. By doing this, the overall speed and reliability of the circuit simulator can be increased.
