My design is based on a FPGA online course I'm taking through Coursesea
I'm seeing a conflict between the compile error and the pin planner
I'm using Quartus 16.1 lite (free), processor MAX10 10M08DAF484C8GES
I did research the forum for help, no luck. I'm also the Max10 datasheets
compile error states 37 pins assigned in I/O bank 8 only 36 I/O pins allowed
versus
pin planner shows 33 pins assigned and 3 pins available, see IO Bank Usage attachment
Per the instructor direction I assigned the pins from a combination of
- pin planner:
- 2 single pins dropped
- dropping grouped bus pins into the bank#
- using the pin Assignment Edito:
OMG I just discovered copying / pasting the compile error below I get the signals i placed in bank 8 plus there's 3 ~signals that
i didn't place but this only adds up to 36 pins not 37.
- So what is the 37th pin?
- why did these signals get placed? One confession I did do a back annotate before re-assigning the pins.
