Embodiment Construction

[0015] Such as figure 1 As shown, a multi-branch parallel simulation method includes the following steps:

[0016] S1, define a simulation soft bus, the simulation soft bus is a virtual bus running in multiple simulators;

[0017] S2. Each simulator receives a simulation task for simulation and is connected to the same virtual bus;

[0018] S3. Each simulation task is divided into three kinds of communication data: clock flow, control flow and data flow;

[0019] The simulator includes clock domain module, control module, interface module and simulation module.

[0020] The clock domain module is used to obtain the communication data of the clock flow and output some clock excitation information to the control module; the control module is used to obtain the communication data of the control flow and distribute and control the clock excitation information, and send clock scheduling to several simulation tasks The driving signal is used to monitor the data of the simulation ...

Abstract

The invention provides a multi-branch parallel simulation method. The method comprises the steps that S1 a simulation soft bus which is a virtual bus running in a plurality of simulators is defined; S2 each simulator receives a simulation task used for simulation and is connected with the same virtual bus; S3 each simulation task is divided into three kinds of communication data including clock flow, control flow and data flow; S4 the three kinds of communication data are divided into different subtasks according to subordinate simulation tasks; S5 each of the plurality of simulators is allocated to execute one or more corresponding subtasks in the simulation task; S6 the simulation task is executed by calling each simulator to execute the distributed corresponding subtask. The method hasthe advantages of fast and stable simulation operation.

Description

technical field [0001] The invention belongs to the technical field of simulation, and in particular relates to a multi-branch parallel simulation method. Background technique [0002] Traditional simulation scheduling belongs to hard real-time scheduling, and its simulation progress is strictly consistent with the physical clock, which may easily cause the simulation model to time out and lead to simulation failure; and in the scheduling center, the interactive data of the distributed model interface that can be stored is limited, far from reaching The large data volume requirements of modern simulation systems; with the development of multi-point parallel simulation systems to multi-user concurrent simulation, it is particularly important to ensure the safe operation of simulation systems. Contents of the invention [0003] The purpose of the present invention is to provide a multi-branch parallel simulation method to solve the problems that the current branch parallel s...
