Dear Masters:

In verilog-a, I need to read a number from a file, but I just find how to write a number into a file, but no read. I wrote a code like this:

analog begin
 file = $fopen("/home/user/myfile.txt");
 rr = $fscanf(file, " %f", real_time);
 $fclose(file);
end

The number in myfile.txt is 100, but real_time=0.

Could you tell me what's wrong in my code.

Many Regards!
