ID:329000 Unable to compute I/O buffer delays for pin "<name>" using Advanced I/O Timing due to problematic board trace model; using capacitive load of <number> pF to determine buffer delay

CAUSE: You have specified a problematic board trace model for the specified output or bidirectional pin, and the Quartus Prime software was unable to determine the I/O buffer delay using Advanced I/O Timing. In order to continue timing analysis an effective capacitive load is computed from the board trace model.

ACTION: Specify a different board trace model for the specified pin.
