Pin Assignments for DE5-Net
In the DE5-Net CD you can find several files for pin assignment.
For instance the .qsf file in one of the demonstrations projects.
Instead of manually assigning pins you can import the .qsf file in Assignments&gt;ImportAssignment of Quartus and then you can eventually rectify the name either in your VHDL/Verilog or in the Pin Planner of Quartus.
You can find for instance several duplication of the 50MHz clock:
set_location_assignment PIN_AW35 -to OSC_50_B3B
set_location_assignment PIN_BC28 -to OSC_50_B3D
set_location_assignment PIN_AP10 -to OSC_50_B4A
set_location_assignment PIN_AY18 -to OSC_50_B4D
set_location_assignment PIN_M8 -to OSC_50_B7A
set_location_assignment PIN_J18 -to OSC_50_B7D
set_location_assignment PIN_R36 -to OSC_50_B8A
set_location_assignment PIN_R25 -to OSC_50_B8D

For button[0] you can find the following;
set_location_assignment PIN_AK15 -to BUTTON[0]

You can assign other pins by editing .qsf file as I mentioned:
set_location_assignment PIN_AG14 -to RS422_DE
set_location_assignment PIN_AE18 -to RS422_DIN
set_location_assignment PIN_AE17 -to RS422_DOUT
set_location_assignment PIN_AF17 -to RS422_RE_n
set_location_assignment PIN_AF16 -to RS422_TE
