Design of MIL-1394 bus simulation card

In the development of MIL-1394 (Military 1394) products, users need to buy simulation equipment withdifferent functions when building simulation network. It is not only expensive,but also a burden for users to be familiar with the configuration mode and application interface of different equipment. Combined with IEEE-1394B (Institute of Electronic Engineers 1394b) and SAE AS5643 (Society of Automotive Engineers Aerospace Standard 5643) protocols, this paper designs a Mil-1394 bus four node simulation card, which is used to simulate the functions of CC (Control Computer) and RN (Remote Node) nodes in 1394 bus. It has four independent 1394 nodes and supports bus data recording error injection and other functions to realize the data transmission of 1394 bus network.
