1.5.4.7. Configure board trace models for Quartus® Prime advanced timing analysis

For a system to operate properly, signal integrity and board routing propagation delays must be taken into consideration. If you use an FPGA with high-speed interfaces in your board design, analyze the board level timing as part of the I/O and board planning.

Differential I/Os at the top left corner are located in the low speed region.

To generate a more accurate I/O delays and extra reports to gain better insights into the signal behavior at the system level, turn on Enable Advanced I/O Timing under the Timing Analyzer category in the Settings dialog box of your Quartus® Prime project. With this option turned on, the Timing Analyzer uses simulation results for the I/O buffer, package, and board trace model to generate the I/O delays.

You can use the advanced timing reports as a guide to make changes to the I/O assignments and board design to improve timing and signal integrity.
