Method and system for realizing dynamic and visual check of variable

Abstract

The invention discloses a method and a system for realizing dynamic and visual check of a variable. The system comprises a resolver library, a design mode module and a run mode module, wherein the design mode module is in communication linkage with the resolver library; the resolver library is in communication linkage with the run mode module; a visual analytic function is configured for the variable according to variable information and the variable information is stored in the resolver library together with the visual analytic function; the variable information and the visual analytic function are acquired from the resolver library and the visual analytic function is used for analyzing the variable; and character string information obtained by after analyzing the variable is transmittedto a check terminal. The visual analytic function is configured to analyze the variable, so the variable checking efficiency is greatly improved and the data checking flexibility is increased. Particularly, a mode of only analyzing one type of variables by one visual analytic function is adopted, so the variable checking stability is further enhanced.

Description

Technical field [0001] The invention relates to a method and a system for dynamically observing and visually viewing variables in an embedded system or a non-embedded system during operation, in particular to a method and system for realizing dynamic visualized viewing variables. Background technique [0002] The embedded system in the prior art generally analyzes and solves problems by viewing the characteristic data of variables. These characteristic data are mostly global variable information and instance data area information. Among them, the global variable information is the system running process. Variable information that always exists. The data information of the embodiment is variable information that is dynamically generated during the running process but is automatically destroyed after the running is completed. It can also be called running-state variable information. Therefore, the system is very useful for debugging and locating problems by observing characteristic...

Problems solved by technology

However, the above two solutions also have great defects. For example, the first solution is basically not allowed to use the debugging environment to test the positioning problem in the official version system, and based on the size and efficiency of the version file, the released version The symbol table information is incomplete, so the scope of action is only applicable to the laboratory environment; in the second scheme, regarding the definition of the structure pointer in the structure, the background cannot do extended analysis for the pointer part, and if specified If the length is longer, the memory copy operation will take longer and have a greater impact on the performance of the foreground. In particular, it is necessary to ensure the consistency of the data structure between the foreground and the background, which brings great difficulties to system maintenance.
