说明：  基于fpga的spi通信测试 可与stm32进行spi通信测试(SPI communication test based on FPGA can test SPI communication with stm32)

说明：  FPGA控制外边led，并实现跑马灯等多种效果，用户可以自行控制(FPGA control outside led)

Multi-Digital Down Converter design.

数字化，宽带化，是当今无线通信的重点主流方向，FPGA以其功能强大，开发周期短，投资少，可重复修改，开发工具智能及软件可升级等特点成为无线通信首选。(Digital, broadband, is the focus of today s mainstream wireless communications, FPGA with its powerful, short development cycle, low investment, repeatable modify, intelligence and software development tools and other characteristics can be upgraded to become the first choice of wireless communication.)

ModelSim的波形比较的功能可以将当前仿真与一个参考数据（WLF文件）进行比较，比较的结果可以在波形窗口或者列表窗口中查看，也可以将比较的结果生成一个文本文件-ModelSim waveform can be compared to the current functional simulation with a reference (WLF paper ), the results can be compared in the waveform window or window List View, it will also compare the results generate a text file
