Hi,
I have used Cyclone 10 LP Nios II 'Hello World' Design which work fine without any error.(opened .par ->upgrade -> start compilation)
Try again downloading the example or create your own design by referring to below link.

Can you share image of you EDA netlist setting or your project itself.
Regards
Anand

Hi Anana,
thanks for ur reply to the query re Nios2 problem. I got it working ok
and am enjoying playing around with the system a bit. The problem I had
I thinks stems from the documentation being a bit out of date. The pdf
guide from the design store talked about compiling the nios2 core from a
qsr source whereas all you have to do is add the qip file to your
project and compile. I traced the compile problem in EDA to a message
like "functional simulation is the only simulation available for the
device type but is turned off".
I turned it on at settings -> EDA -> More EDA Netlist Writer Settings ->
Generate functional simulation netlist, and compilation was successful.
That was before I added the qip file, hence I dont know if it was
necessary, but it was still turned on when I compiled with the qip file
added without problems.
Thanks again for ur response
P.S. Do u know of any documentation for the JTAG UART interface that
lets you interact with the board from ur own programs without using the
nios2-terminal program. I can always redirect the stdin, stdout of
nios2-terminal which is probably easier anyway.
P.P.S. I was using quartus 18.1 Lite on Linux.
