Application of hardware desription languages to specification of the point module interlocking logic

Abstract

There is proposal to apply hardware description languages HDL in this paper to specify control movement devices in transport. Languages HDL, mainly used to design specialised programmable and reprogrammable digital devices, allow both simple and precise ways to describe functionality as well as a structure of both combine and sequence control devices. Concurrent processing instructions, built into languages, allow describing hardware realisations of control algorithm processes.
