Hy I have to save some metrics about my design. I want to save the istant of a particular event on a file, my code is write in Verilog and I'm using modelsim. I was thinking to use the istruction $time to capture a particular istant of time, and if it's possible to save it on a file. How can I do this? is it possible? Could I use $time and $writmemb (or $writememh) to solve my problem.

Thx for helping me.
 

Yes it is possible and it's not hard to do.

You can get the simulation time using this:
reg time;
$monitor($time,,"set=%b",time);
Click to expand...

And then save it in a file using this:
integer file_ptr; // file pointer

file_ptr <= $fopen("C:\\...whatever...\\your_file.txt", "wb");
$fwrite(file_ptr,"%d \n",time);
Click to expand...

I don't recomend using $writememh or $writememb because they only store data as hex or binary. Verilog as other functions such as $fwrite and $fread which are very similar to C programming and easier to use.

Hope it helped.
