Abstract

The present disclosure relates to a multi-granularity computer simulation operation information collection method based on hook points, and relates to the field of data collection technology, wherein the method includes: obtaining an information collection request; the type identification corresponding to the information collection request is the first identification In the case of , generate an information collection strategy according to the information collection request; send the information collection strategy to the simulation model, so as to collect the events of the simulation model according to the information collection strategy through the built-in information collection hook function of the simulation model Information: store the event information in an information warehouse through the information collection work thread corresponding to the simulation model. By adopting the above-mentioned technical solution, by running lightweight information collection hook points in the simulation model to collect simulation operation information data, relevant information data can be collected accurately and quickly to support problem analysis and fault location of the software running on the simulation system , to reduce the impact of information collection on the simulation process.

Description

technical field [0001] The present disclosure relates to the technical field of data collection, in particular to a hook point-based multi-granularity computer simulation operation information collection method. Background technique [0002] Embedded system design and development based on simulated virtual environment, as a brand-new agile development model, can effectively support system designers to conduct dynamic behavior analysis on a virtual platform separated from physical hardware, but dynamic behavior analysis requires a series of information data. Including processor status information, memory information, interrupt information, bus information, stimulus information, function execution time, function running trajectory, dynamic code execution information, and execution unit timing information, etc. [0003] At present, the common dynamic behavior analysis method is program instrumentation. This method inserts stub code into the source code to check the program code...
