103 Rise and fall times depend on the I/O standard, drive strength, and loading. Altera recommends simulating your configuration.
104 If you connect a PHY that does not implement clock-to-data skew, you can delay TX_CLK by 1.5–2.0 ns with the HPS I/O programmable delay, to meet the PHY's 1 ns data-to-clock skew requirement.
105 If you connect a PHY that does not implement clock-to-data skew, you can meet the HPS EMAC’s 1 ns setup time by delaying RX_CLK by 1.5–2 ns, using the HPS I/O programmable delay.
