Hi @MGhad3 ,
Yes, you can program .sof file without any license.
Open Quartus with 30- days trial mode or without compilation mode go to Tools-> programmer ->auto detect ->select device->right click and change the file ->click on start.
Intel altera recommended to use programmer from same Quartus version & edition used to generate .sof file.
Let me know if this has helped resolve the issue you are facing or if you need any further assistance.
Thanks for your response.
Does it allow programming SOF files containing NIOS processor? after programming do I have to keep the USB blaster plugged in? or it can be removed ? I noticed in Web edition you have to have the usb blaster plugged in.
Yes, but it will be time-limited sof file for Quartus pro & Quartus std.
We can use Quartus Lite to generate sof(not a time limited) only if, we are not using any IP's which required license.
For example: If we use Quartus Lite to design a system with Nios II/f(which requires license) in 30-days train mode of quartus. Tool will generate a time limited sof file.
You can also download just the Programmer if you don't want to download and install the full Quartus software:
Click "Select by Software" and then choose "Programming Software."
