188.8.131.52. Specifying Near-End vs Far-End I/O Timing Analysis
You can select a near-end or far-end point for I/O timing analysis. Near-end timing analysis extends to the device pin. You can apply the set_output_delay constraint during near-end analysis to account for the delay across the board.
With far-end I/O timing analysis, the advanced I/O timing analysis extends to the external device input, at the far-end of the board trace. Whether you choose a near-end or far-end timing endpoint, the board trace models are taken into account during timing analysis.
