Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] A scalable embedded simulation test system, the system includes a user interface layer and a virtual machine simulation layer; as figure 1 shown.

[0025] The user interface layer is a user interaction layer completely independent of other layers. It only interacts with the underlying virtual machine through command line calls. The stream is redirected to the virtual machine to realize inter-process communication. When the user interface program is initialized, a query command is first sent to the virtual machine. By querying all the simulation commands and information provided by the virtual machine, the virtual machine feeds back the command and information to The user interface and all its functions are initialized, and the above process is automatically completed when the simulation test software is started.

[0026] Among them, the user interface is dynam...

Abstract

The invention provides an extensible embedded simulation test system which is formed through minimizing coupling degree between an operation interface and an underlying virtual machine and defining an excellent module design and is used for overcoming the disadvantage of insufficiency of embedded software testing caused by overdependence on target hardware in an embedded software testing process. The system comprises a user interface layer and a virtual machine simulation layer, wherein the user interface layer is a user interaction layer which is completely independent of other layers, and is called to interact with the underlying virtual machine only through command lines, and the virtual machine simulation layer is used for realizing the simulation of the target hardware. The system is applicable to virtual machine frameworks of a plurality of processors, establishes abstract embedded processor models, and provides an interface so as to integrate an upper software testing function.

Description

technical field [0001] The invention belongs to the field of embedded simulation test, and in particular relates to an expandable embedded simulation test system. Background technique [0002] Traditional embedded software testing is based on hardware simulation, which is characterized by a high degree of simulation and fast speed, but its disadvantage is that it needs the support of the target hardware, and it cannot be put into testing work before the target hardware is formed. The bottleneck of testing delays the testing progress of embedded software to a certain extent and may ultimately affect the stability of embedded devices due to insufficient software testing. [0003] In order to overcome the shortcomings of insufficient embedded software testing caused by excessive dependence on the target hardware in the process of embedded software testing, and to achieve a strong guarantee for the quality of embedded software, embedded software engineers need to be separated fr...
