Design And Implementationof SAE AS5643Simulation Equipment Based On The Xilinx FPGA

With the rapid development of aviation system, the bandwidth, accuracy andinstantaneity of data transmission are increasingly significant. To address therequirement of new generation aviation system, standard IEEE-1394B bus protocolshould be restricted. Thus new1394B interface requirement SAE AS5643wasdeveloped. To simulate the reliability of1394bus system in aviation system, a series ofground virtual simulation devices including CC simulation_card were designed.CC card is a visual simulator to simulate the node function of1394buses on theground. It contains three nodes,In the system CC simulation_card can be linked tosystem bus through the root node function, thus achieving AS5643communicationprotocol processing and information interaction between peripheral and host system.This thesis detailed the design of CC simulation_card based on FPGA. Allmodules were achieved by Verilog coding. To test the accuracy of FPGA, the timingsimulation of CC simulation card was performed through Xilinx ISE developmentenvironment and QustaSim simulator. The design of FPGA was achieved.Designs have been achieved as set out in the thesis, FPGA synthesis report hadbeen met, virtual simulation and FPGA test has been carried out, the basic featuresalready meet the design objectives.It contains three nodes with the function of datasending or receiving, faults injection, buttery management, self-setting of heart beinitial value, self-test of VPC and CRC.
