Data communication over the network is efficiently carried out with the help of protocol. Protocol is set of rules that define the format of frame, packet or message that are exchanged between devices. HDLC i. e. High level data link control protocol is one of the protocol defined by International Organization for Standardization (ISO) for data link layer of OSI reference model. HDLC is bit oriented protocol and widely used in the network. It is used to send the data in proper frame format. This paper discusses the design of HDLC transmitter coded in VHDL and its simulation in Modelsim software.
