文章目录前言1.创建自定义IP核工程2.创建Vivado工程3.Vitis软件设计4.下载验证5.如何修改自定义的IP核前言无仅作记录不具有参考价值。1.创建自定义IP核工程这里的名字可以和图中不同 这里取的是breath_led_ip_test因为之前已经有个我自己建立的breath_led_ipIP核这里只是为了展示IP核的建立过程verilog代码还是使用的是breath_led_ip_test的名字vitis代码中用的是breath_led_ip的名字后面会有一个使用breath_led_ipIP核的工程打包zip给你们下载这里要关注的是建立过程在D:\ldy\VivadoIPs\custom_ip\ip_repo\breath_led_ip_test_1.0\hdl中添加breath_led.v文件并导入到工程中修改前的breath_led.v:modulebreath_led(input sys_clk,input sys_rst_n,output reg led);parameter CNT_2US_MAX100;reg[6:0]cnt_2us;reg[9:0]cnt_2ms;reg[9:0]cnt_2s;reg led_flag;always (posedge sys_clk or negedge
