Visual modeling method for virtual operation environment of complex embedded system

Abstract

The invention relates to a visual modeling method for a virtual operating environment of a complex embedded system, which comprises the following steps: 1, constructing a graphical model of an entity object; 2, configuring a graphical model interface and attributes; step 3, generating an equipment simulation model: converting the interface and the attribute described by the graphical model into corresponding interface functions and attribute variables, automatically generating framework codes of the equipment simulation model, and developing logic functions of the equipment simulation model based on the framework; 4, packaging and persistently storing the equipment simulation model, including packaging a graphical interface operation, and establishing bidirectional mapping between the equipment simulation model and the graphical model; and forming a graphical model and an equipment simulation model library; and 5, generating a virtual operation environment construction and system configuration file. According to the invention, the construction process of the virtual running environment of the complex embedded system can be effectively simplified, so that the research and development efficiency and the test sufficiency of embedded software are improved.

Description

technical field [0001] The invention relates to embedded system development technology, in particular to a visual modeling method of a complex embedded system virtual operating environment. Background technique [0002] During the development of embedded systems, 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, external devices, connection buses, and supporting excitation devices, etc., but is limited by the embedded system hardware. Due to limited resources and strong specificity of hardware interfaces, it is difficult to accurately count the dynamic execution of embedded software, and it is difficult to guarantee the efficiency of embedded software development and test adequacy. Therefore, a virtual operating environment modeling method is often used to model and simulate the complex embedded system target machine, build a reliable...
