Design and Verification of VHDL Code for FPGA Based Slave VME Interface Logic

Abstract

Versa Module Europa (VME) bus is used in various applications in order to ensure safety and security. VME64x based Real Time Computer (RTC) system with various types of Input / Output (I/O) hardware modules is being designed and developed for use in various safety critical and safety related Instrumentation & Control (I&C) systems. Analog Output Card (AOC) is one of the I/O hardware modules as part of VME64x RTC development. The AOC uses Field-Programmable Gate Array (FPGA) as VME bus system controller. This paper discusses the design and development of a VME64x bus controller so as to meet the required specifications correctly.
