Design of a CAN interface for custom circuits

Abstract

This paper presents the experience of the development of a CAN interface to be integrated in custom circuits (ASICs, FPGAs). The CAN controller has been designed in VHDL, so it can be targeted to different implementation technologies. The design method of the block is also presented in the paper as an experience of how to easily design digital systems to be reused in different applications, assuring its quality and reliability.
