Providing a unified interface, either bus or non-bus, the modeling interface class provides all the common functionality sets available for the generic interfaces (e.g., A664, MILSTD-1553, ARINC-429, etc.).

In the embodiment of the specification, the data monitoring function can monitor the whole network data, is convenient for debugging and integration of software modules, and can manually modify the data to realize static simulation and simulation data.
Considering that the bandwidth in the middle of data needs to be increased as hardware modules and models increase in the system, we can use the function of data flow to ensure that the transmission capability of continuous data flow is realized with minimum overhead.
Thus, in the present embodiment, we can periodically batch package the data, or form a queue.
