help me with fwrite and fopen commands in Verilog

fwrite and fopen

I have been trying on the verilog HDL code to make a notepad print the following.

1 2 3 4 5
1 2 3 4 5


The number in the file, which end at 5 as mention above, must be able to modify easily as the counter may need to count from 1 to 32.

I tried alot of times, and i only get a blank .txt notepad file.

I am still new to verilog, and the fwrite and fopen command. I hope someone kindly answer my question.

Thanks alot =)

Re: fwrite and fopen

Which simulator are you using? If you are running a Windows-based Verilog simulator (such as Modelsim/PE), then remember to execute $fclose() at the end of your Verilog program. Otherwise, the operating-system (Windows) won't update/release the open-textfile until you quit the simulator.

Yup, i am using modelsim for Windows. After i close the simulator, its still blank, so i think theres something wrong with my program. Is there any sample or example codes i can refer to?
