HPS pins

Hello,

I have the following questions about assigning HPS pins:

  1. Do we need to assign HPS pins location in quartos (as I understand the pins location should already be known for each device)
  2. when using HPS peripheral, what is the meaning of number (0,1,2) in "I/O set 0", "I/O set 1" ... I tried to change between these option and I see no change in the pin selection table.

Thank you!

    Hi,

    In the pin assignment the 0,1,2 represent low, medium, high. For example in slew rate, by default, the slew rate is 1 which is fast.

    The high slew rate will tend to have faster 0 -> 1 or 1 -> 0.

    I hope this this answers your question.
