Sorry,
this should be a valid link. Copied from site search. Intel could spend quite a bit more effort to maintain website integrity. I'll post my latest copy, not necessarily current version.

Frank
P.S.: There's only one setting for unused pins. If you want other initialization of some pins, they must be defined as ports in your design top and assigned in pin planner to pin locations. Initialization of output to '1' can done in port definition, weak pull-up feature of input or tri-stated inout in pin planner or assignment editor.

Hi,
the requested manual can be located on Intel FPGA web site, but I wonder what your problem is. I'm regularly setting default state of unused pins in Device and Pin Options, as seen below
.qsf setting is
set_global_assignment -name RESERVE_ALL_UNUSED_PINS "AS INPUT TRI-STATED WITH WEAK PULL-UP"
Regards
Frank

Thanks frank.
It helped me a lot.
However, I can't download the PDF file from the link provided.
If you know of a site where I can download it, please let me know.
An additional question is,
I want to make some unused pins internally pull-up and the rest high output.
What should I do in this case?
