This code to a large extent improve the coding for data transmission error detection and error correction ability, so as to improve the quality of the digital baseband signal communication. This design is based on the EDA technology of the HDB3 encoder design, with VHDL as the language tool, QuartusII software for the design platform, as well as to build a hardware circuit to complete the design of the HDB3 encoder. The whole design is divided into 3 modules, which are separately designed, and the last 3 modules are cascaded to implement the HDB3 encoder. The design specification are first introduced EDA technology and device programming, development tools using the overview and characteristics, the AMI code and HDB3 code has carried on the key elaboration and analysis of, which the subsequent design plays a major role. Secondly, through the comparative analysis of the design scheme of the three kinds of HDB3 encoder, the optimal scheme is obtained. Each module of the HDB3 encoder to achieve basic principle and of VHDL code method are introduced in detail, and describes the flow chart of the function module design, through the simulation waveform to verify the function of each module. Finally through the software simulation, hardware circuit test method to verify the correctness and rationality of the design of the HDB3 encoder. From the simulation results we can see that the design of the entire design basically completed the HDB3 encoder design, but the output relative to the output of the clock pulse on the delay.
