作者你好，在编译综合中我遇到一些问题不知道如何解决，在tb-clahe-top.v程序中的第97行， while(pixel_cnt < 32'd921600) begin start_num = {$random}%721 + 2; pause_num = {$random}%11 + 2; while(start_num > 1) begin start_num = start_num - 1;

(period);

     end
     while(pause_num > 1)
     begin
     pause_num = pause_num - 1;
     TVALID_in = 0;
     #(period);
     end
     TVALID_in = 1;
     end

出现了这样的错误，[Synth 8-3380] loop condition does not converge after 2000 iterations 不知道该如何解决与此同时还有[Synth 8-6156] failed synthesizing module 'tb_CLAHE_top' [Common 17-69] Command failed: Vivado Synthesis failed 是操作有误还是程序需要修改呢，期待您的回复

tb文件里是测试激励，是不可综合的喔。更换顶层文件试试

感谢您的回复，早上这个问题解决了，还有个问题想问您的是，是不是再加一个IP核ram的就可以成功综合了，（目前已经成功综合），作为新手还有一些不太懂，tb里面读取的.bin文件是图像转化而来的吗，可以直接读取png或者bmp吗
