[0024] The steps S101 to S103 shown in the embodiments of the present application are as follows: a developer acquires global requirement information of a system to be developed and designed, then constructs a verification comprehensive platform based on an MBSE architecture, identifies and analyzes the global requirement information of the system through the verification comprehensive platform to determine detailed requirements of each subsystem and component in the system, and establishes a verification model at the global system level according to the identification and analysis result; then, each subsystem or component is split according to the global requirement information of the system and the established verification model, and corresponding simulation test instructions are generated; the generated simulation test instructions are issued to a modular integrated platform, such as a PC104 stackable hardware platform; the modular integrated platform is provided with a plurality of different interfaces, and simulation test devices corresponding to each subsystem or component are connected to the modular integrated platform through corresponding interfaces of the modular integrated platform; the simulation test devices include a software simulation system and a hardware test device, which perform simulation and testing at the software level and the hardware level, respectively; the modular integrated platform drives the simulation test devices connected thereto to perform simulation on the corresponding subsystems or components, and feedback simulation data, and uploads the test data to the cloud; the modular integrated platform performs corresponding statistical collection on the simulation test data fed back by each simulation test device, such as unifying the data format of the fed-back simulation test data; finally, the verification comprehensive platform analyzes the simulation test data processed by the modular integrated platform, globally evaluates and optimizes the system, determines global simulation test results of the system, and evaluates the performance of the system, etc.

[0025] In step S101 of some embodiments, a PC104 stackable hardware architecture platform can be used as the modular integrated platform to perform simulation tests on the system. Other different scalable hardware platforms, such as PXI, CompactPCI or VPX, etc. can also be used.

At the same time, the simulation test data fed back by the modular integrated platform is matched and analyzed with the abnormal information in the system requirement information to determine whether an abnormality occurs in the simulation test process and the type of the abnormality.

[0036] In step S403 of some embodiments, if the simulation test data is matched with the abnormal information in the system requirement information successfully, it can be determined that there is an abnormal condition in the simulation test data of the subsystem or component, the type of the abnormality is determined by analyzing the matching result, the corresponding processing scheme or optimization suggestion is determined according to the analysis of the type of the abnormality and the preset processing scheme, the performance index information of the subsystem or component for simulation test is obtained by matching the simulation test result determined by the abnormal information and the processing scheme or optimization suggestion obtained by analysis, and the evaluation result of the subsystem or component for simulation test is obtained.
