Record the time to V
Compare the results of steps 2 and 4. The increase or decrease in
delay should be added to or subtracted from the I/O Standard
Output Adder delays to yield the actual worst-case propagation
delay (clock-to-output) of the PCB trace.
Output pin timing is reported at the output pin of the FPGA device. Additional
delays for loading and board trace delay need to be accounted for with IBIS model
simulations.
