基于FPGA的PROFIBUS-DP从站实现

The design of PROFIBUS-DP slave station based on FPGA

以FPGA为主控芯片,采用Verilog硬件描述语言实现协议内容,从而代替SPC3协议芯片,实现从站各个通信模块控制器的逻辑功能,构成一个完整的PROFIBUS-DP从站,并且给出了物理层(PHY)的详细设计过程。该技术的使用将不再受外国供货商的限制,并且降低PROFIBUS-DP总线系统的成本,具有一定的实际应用价值。

This design is based on FPGA , using Verilog HDL to achieve the agreement, replacing the SPC3 protocol chip, realized the each communication module controller logical function of slave station, making up a PROFIBUS-DP slave station, and gived the Physical Layer（PHY） for the detailed design process. Using this technology will no logger be limited by foreign suppliers and reduce the cost of PROFIBUS-DP, has some practical significance.
