US 2012/0084062 A1 · DYNAMICALLY SELECTING MASTER CLOCK TO MANAGE NON-LINEAR SIMULATION CLOCKS

Abstract

Systems and methods that efficiently simulate controlled systems are presented. A simulation management component (SMC) controls simulation of a controlled system by controlling a desired number of nodes, each comprising a controller (e.g., soft controller) and a simulated component or process, which are part of the controlled system. The simulation can be performed in a step-wise manner, wherein the simulation can comprise a desired number of steps of respectively desired lengths of time. For each step, the SMC dynamically selects a desired clock (e.g., currently identified slowest clock) as a master clock for the next step. The SMC predicts a length of time of the next step to facilitate setting a desired length of time for the next step based in part on the predicted length of time. As part of each step, components can synchronously exchange data via intra-node or inter-node connections to facilitate simulation.

Dependent claims

A system that facilitates simulation of a controlled system, comprising:

a plurality of clocks comprising at least a first clock and a second clock, wherein the first clock is configured to be associated with a controller and the second clock is configured to be associated with a simulation component in the simulation of the controlled system;
and
a simulation management component that is configured to dynamically select a clock of the plurality of clocks to be a master clock based at least in part on speed of the clock relative to other clocks of the plurality of clocks and predefined simulation criteria.
