利用FPGA实现频率测试,基于VHDL实现,具有良好的测试性能可直接使用...

说明：  本实验为UART回环实例，实验程序分为顶层unrt_top、发送模块uart_tx、接收模块 uart_rx，以及时钟产生模块clk＿div。uart＿rx将收到的包解析出8位的数据，再传送给 uart_tx发出，形成回环。参考时钟频率为100MHz，波特率设定为9600bps。(This experiment is an example of UART loop. The experimental program is divided into top-level unrt_top, sending module uart_tx, receiving module uart_rx, and clock generation module clk_div. Uart_rx parses the received packet into 8 bits of data and sends it to uart_tx to send out, forming a loop. The reference clock frequency is 100 MHz and the baud rate is set to 9600 bps. stay)

说明：  基於空間向量調變的開關法，在於載波做比較切出方波再送至開關讓馬達啟動(Based on the switching method of space vector modulation, the square wave is cut out for carrier comparison and sent to the switch to start the moto)

说明：  基于fpga的verilog实现ad及uart，并进行仿真验证(Verilog based on FPGA implements AD and uart, and carries out simulation verification)

说明：  在quartus下搭建的数字锁相环，能实现频率自动跟踪。(The digital phase-locked loop built under quartus can realize automatic frequency tracking.)
