阻止，因为它不起作用，我尝试使用fsancf而没有任何正面结果。
请帮忙吗？
完整代码：
scan_faults = $fgets(file_faults , string , data);答案 0 :(得分：1)
从IEEE Std 1800-2012§21.3.4.2一次读一行：
可以使用
$fgets从文件中读取一行。例如：
将integer code; code = $fgets ( str, fd );fd指定的文件中的字符读入变量str，直到填充str，或者读取换行符并将其转移到str或EOF遇到条件。如果str的长度不是整数字节，则不使用最重要的部分字节来确定大小。
如果从文件读取错误，则code设置为零。否则，在code中返回读取的字符数。应用程序可以调用$ferror来确定最近错误的原因（参见21.3.7）。
因此，您的代码需要看起来像这样：
integer file_faults;
integer scan_faults;
reg [7:0] data; // needs to be an "integral number of bytes in length"
initial begin
file_faults = $fopen("faults.txt", "r");
if (file_faults == 0) begin
$display("data_file handle was NULL");
$finish;
end
while (!$feof(file_faults)) begin
scan_faults = $fgets(data, file_faults); // arg order was wrong in original
$display("scan_faults: %0d data: %s", scan_faults, data);
end
$fclose(file_faults); // Close file before finish
$finish;
end
如果你想要从一个特定格式的变量中输出变量，那么请查看$fscanf。请参阅IEEE Std 1800-2012§21.3.4.3阅读格式化数据
