Excalibur Nios Development Board
I would appreciate any kind of help because, I can not find any information about this FPGA.
Which device are you using?
To choose Quartus version, its depends on which device you're using to build your project.
Kindly check the below link, which Quartus version supports for your devices.
The Excalibur Board uses an Apex 20k, which is over 20 years old!!
The last version of quartus to support this part is Quartus 9 (which is 9 years old!)
I suggest you throw this board away, and build with something more modern and more capable.
Something like this?
that costs $99 is far more capable than the board you are going to try and use.
