2.2.3.5. Guidelines: Programmable De-Emphasis

  • The de-emphasis effect reduces eye height. If you use a non-default de-emphasis setting, perform an IBIS or HSPICE simulation to estimate the electrical performance of the I/O buffer.
  • To get the optimal setting for your design, start the simulation with the lowest de-emphasis setting. From there, fine-tune the setting until you get the best signal integrity.
