Automatic generation of VHDL code for a railway interlocking system

摘要

This article introduces a novel technique to automatically analyse a railway network geographical representation and produce a suitable FPGA railway interlocking system by generating its VHDL hardware description. This approach accelerates the design, implementation and testing phases on different topologies. We review the automated tools developed - which are part of a comprehensive workflow - and present the results for topologies of varying complexities.
