A Visual Modeling Method for Virtual Operating Environment of Complex Embedded Systems

Abstract

The present invention relates to a visual modeling method for a virtual operating environment of a complex embedded system, which includes: the first step, constructing a graphical model of an entity object; the second step, configuring the graphical model interface and attributes; the third step, generating The equipment simulation model includes: converting the interfaces and attributes described by the graphical model into corresponding interface functions and attribute variables, automatically generating the framework code of the equipment simulation model, and developing the logical function of the equipment simulation model based on this framework; the fourth step , Encapsulate the equipment simulation model and store it persistently, including: encapsulating the operation of the graphical interface, and establishing a bidirectional mapping between the equipment simulation model and the graphical model; System configuration files. The invention can effectively simplify the construction process of the virtual operating environment of the complex embedded system, and further improve the efficiency of embedded software research and development and the adequacy of testing.

Description

technical field [0001] The invention relates to an embedded system development technology, in particular to a visualization modeling method for a virtual operating environment of a complex embedded system. Background technique [0002] In the process of developing an embedded system, the development and debugging of embedded software is generally carried out through the real target machine operating environment. The target machine operating environment includes processors, peripheral devices, connection buses, and supporting excitation devices, etc., but it is limited by the embedded system hardware. Due to the characteristics of limited resources and strong hardware interface specificity, it is difficult to accurately count the dynamic execution of embedded software, and it is difficult to guarantee the development efficiency and testing adequacy of embedded software. Therefore, a virtual operating environment modeling method is often used to model and simulate complex embe...
