Problems solved by technology

In addition, if each model performs ultra-real-time co-simulation, due to the different logical complexity of each model, the time-consuming solution is different, resulting in inconsistent physical time in each model, and co-simulation will cause logical confusion

Abstract

The invention discloses a scheduling method and device for super-real-time joint simulation, and the method comprises the steps: carrying out the timing of each model through a scheduling system during joint simulation, carrying out the accumulation of natural time, stopping the natural accumulation of time when the token state of a registered model reached by the next step length is detected to be a sent state, and waiting for the registered models which are not solved completely in the registered models reached by the next step length to complete the solving. Therefore, unification of physical time of all models of joint simulation is guaranteed, so that logic of joint simulation is not disordered, the simulation progress is accelerated, and the simulation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of electronic system design and simulation verification, in particular to a scheduling method and device for super-real-time joint simulation. Background technique [0002] At present, in the design of electronic systems, each subsystem is independently mathematically modeled. Taking the aircraft electronic system as an example, the mathematical model of each device is established according to the division of the future aircraft electronic system (aviation electronics, control, electromechanical, etc.). Then carry out model verification, among which, during model verification, most of them use the logic solution of modeling tools to carry out super real-time simulation. In the co-simulation stage, each model is downloaded to the real-time simulator, and each model is solved in real time according to the physical time, and the simulation is carried out according to the respective timing during the running of...
