Multi-Rate Parallel Circuit Simulation

Abstract

Methods and systems are disclosed related to multi-rate parallel circuit simulation. In one embodiment, a computer implemented method of partitioning the circuit into a plurality of partitions, wherein each partition is represented by a set of linear differential equations, determining a simulation time step for each partition of the plurality of partitions, grouping the plurality of partitions into multiple groups, wherein each group includes one or more partitions having simulation time steps within a predefined range of each other, and solving the multiple groups with their corresponding simulation time steps in parallel.

Description

technical field [0001] The field of the invention is electronic design automation, and in particular, the invention relates to multi-rate parallel circuit simulation. Background technique [0002] Integrated circuits are made of components such as resistors, capacitors, inductors, transformers, transmission lines, diodes, bipolar junction transistors (BJTs), junction field effect transistors (JFETs), metal oxide semiconductor field effect transistors (MOSFETs), metal T A network of circuit elements such as semiconductor field effect transistors (MESFETs) and thin film transistors (TFTs). [0003] With the development of technology, integrated circuits are becoming more and more complex, requiring the use of powerful numerical simulation programs. For example, circuit simulation is an essential link in the design process of integrated circuits, which can help circuit designers to verify the function and performance of their designs without going through expensive manufacturi...
