Paper Title - FPGA Based Rs-422 Utilized Uart Protocol Analyzer For Avionics Units
Avionics units such as Line Replaceable Units (LRU’S) consists of many interfaces. The complexity of these
interfaces has been increasing rapidly because of the rapid growth of Integrated Circuits (ICs) technology. As a consequence,
it became essential to validate the interface circuits in hardware to overcome the product failures. This paper presents a novel
approach for validating Rs-422 interface of an avionic unit. A dual Universal Asynchronous Receiver Transmitter (UART) is
designed and implemented utilizing the RS-422 standards. The 8-bit dual UART is coded in VHDL, synthesized and
simulated using Xilinx ISE and ISim version 14.5 and realized on Spartan 6 FPGA to achieve compact, stable and reliable
data transmission. The results indicate that this analyzer eliminates the need for higher end, expensive testers and thereby it
can reduce the development time and cost.
