int file;
task writeQueueToFile(string filename, reg [7:0] queue[$]);if (filename ) begin$display(Error: Invalid file name);return;endfile $fopen(filename, w);if (file 0) begin$display(Error: Unable to open file %s, filename);return;endforeach (queue[i]) begin$fwrite(file, %d\n, queue[i]);end$fclose(file);$display(Queue contents written to file %s, filename);
endtask
创建一个data_log文件夹存入文件数据可以传入数字类型 $sformat(filename, ./data_log/%0d_%0d_%0d_0.txt, f_num, lane_num,dt);writeQueueToFile(filename, dl0_data);完整的测试方案
