FPGA采样AD9238数据并通过VGA波形显示例程 Verilog逻辑源码Quartus工程文件+文档说明,FPGA型号Cyclone4E系列中的EP4CE6F17C8，Quartus版本17.1。 ADC 模块型号为 AN9238，最大采样率 65Mhz，精度为 12 位。实验中把 AN9238 的 2 路输入以波形方式在 HDMI 上显示出来，我们可以用更加直观的方 式观察波形，是一个数字示波器雏形。 module top( input clk, input rst_n, output ad9238_clk_ch0, output ad9238_clk_ch1, input[11:0] ad9238_data_ch0, input[11:0] ad9238_data_ch1, //vga output output vga_out_hs, //vga horizontal synchronization output vga_out_vs, //vga vertical synchronization output[4:0] vga_out_r, //vga red output[5:0] vga_out_g, //vga green output[4:0] vga_out_b //vga blue ); wire video_clk; wire video_hs; wire video_vs; wire video_de; wire[7:0] video_r; wire[7:0] video_g; wire[7:0] video_b; wire grid_hs; wire grid_vs; wire grid_de; wire[7:0] grid_r; wire[7:0] grid_g; wire[7:0] grid_b; wire wave0_hs; wire wave0_vs; wire wave0_de; wire[7:0] wave0_r; wire[7:0] wave0_g; wire[7:0] wave0_b; wire wave1_hs; wire wave1_vs; wire wave1_de; wire[7:0] wave1_r; wire[7:0] wave1_g; wire[7:0] wave1_b; wire adc_clk; wire adc0_buf_wr; wire[10:0] adc0_buf_addr; wire[7:0] adc0_bu
