Step 103: and verifying the structure, attribute and integrity of the converted interface function data to ensure the consistency of the interface function and the original interface control file. The part directly extracted in step 102 only needs to be verified for consistency with the original interface control file, and the part which can be converted through calculation needs to be analyzed for the calculation process and the correctness of the calculation process is proved.
Step 104: after verification is completed, interface function data and analysis reports are issued to all stakeholders. The change management of the interface function data extracts the backup copy in the form of an intermediate file, supports the editing and changing of a designer, and forms a modification log at the same time.

By establishing the mapping between each application data and the IP address of the communication UDP port, an application developer can directly find the corresponding UDP port according to the parameter name, and the analysis result of the application function data can be visually displayed by inputting the UDP port into the wireshark display filter. A plurality of UDP ports are overlapped among AFDX PDUs defined by a plurality of interface functions, one PDU message format definition can be uniquely identified by the UDP ports inside the AFDX PDUs, and therefore the a664 plug-in needs to set the interface function aimed by the a664 plug-in before running, and the problem can be solved only by editing a664.lua setting.
