protel经典教程，并附有一张电路设计原理图(protel classic tutorials, together with a circuit design schematic)

这是篇<基于FPGA 的OFDM 宽带数据通信同步系统设计与实现>, 觉得甚是有用，大家共同学学。(This is the article <FPGA-OFDM-based broadband data communication systems design and implementation of synchronous> that even be useful, we all learn together.)

说明：  通过iic总线实现数据的读和写，以及基于的modelsim测试。(Through the iic bus to achieve data reading and writing,and based on the modelsim test.)

本文以 VHDL 语言编码得到了 AMBA 与 AHB 总线仲裁。这里在本文中，我们设计了 AMBA 总线协议，将用于多奴隶通信环境，多主
