9.12.1. Performing I/O Timing Analysis with Third-Party Simulation Tools

Intel recommends that you perform I/O timing analysis using the third-party simulation tool flow because this flow involves post layout simulation that can capture more accurate I/O timing. This method is also easier because it only requires you to enter the slew rates, board skews, and ISI values in the parameter editor.

To perform I/O timing analysis using third-party simulation tools, follow these steps:

  1. Use a third-party simulation tool such as HyperLynx to simulate the full path for DQ, DQS, CK, Address, and Command signals.
  2. Under the Board Settings tab of the parameter editor, enter the slowest slew rate, ISI, and board skew values.
