Embodiment Construction

[0028] Concrete steps of the present invention are as follows:

[0029] 1 Establish a model conversion framework

[0030] Model to framework such as figure 1 As shown, it is divided into three layers. The top M3 layer is the meta-meta-model layer, M2 is the meta-model layer, and M1 is the model layer. According to the relationship among various models in model-driven theory, meta-metamodel can generate meta-metamodel and meta-model, and models can be generated according to meta-model. The meta-meta-model can be defined by itself, and at the same time, it can generate a requirement model meta-model, a simulation model meta-model, and ATL language. The requirement model meta-model generates the requirement model, the simulation model meta-model generates the simulation model, and the ATL language generates the ATL model. For the user, it only needs to input the demand model, and through a series of conversions, it will be automatically converted into a simulation model.

Abstract

The invention aims to resolves the problem that a demand model is difficult to be verified and provides a transfer method from the demand model to a simulation model. The transfer method enables the automatic transferring from the demand model to the simulation model to be realized. The transfer method includes firstly designing a transferring frame from the demand model to the simulation model. On the basis, a meta-model of demand model, a meta-model of simulation model, a transferring rule from the meta-model of demand model to the meta-model of simulation model are respectively designed. Finally the automatic transferring from the demand model to the simulation model is realized. The transfer method enables the isomorphic property of the two different models of the demand model and the simulation model to be realized. The development efficiency of embed software is increased. The development of driving model is rich and improved. The transfer method also provides technical support for embed software in flight control system, highway control system, airborne avionics system and the like.

Description

technical field [0001] The invention relates to a model conversion method from a demand model to a simulation model. Background technique [0002] Requirements modeling is an important activity in software requirements engineering. Requirements engineers use different modeling methods to identify, understand, and mine the expectations of requirements providers for the system, so as to build structural models, behavior models, or other Various pairs of models showing different characteristics of the software to be developed. How to verify the correctness of the requirement model, you can use a formal method, but the formal method is difficult to understand and requires software developers to have a strong mathematical foundation. For this reason, we use simulation to verify the correctness of the demand model. How to transition from the requirement model to the simulation model, usually software developers manually complete the simulation model according to the requirement ...
