I am working on developing an addon card with PCIE Gen3. I dont need the wake functionality in my design. So the wake# pin, can be left open as not connected or any pullup/pulldown required. (i.e) If I dont need the wakeup then how this pin should be connected?
Also anyone explain me the PERST# pin. When reading the specifications, i came to know,its like a powergood signal which is high when power is within specified levels & clock is stable. What will happen if I pulldown/pullup this pin permanently?

I think WAKE # is open drain, so when you do not want to use it can be left as NC
For PERST please check below link
Hope this helps

If the add-in card has wakeup capabilities, it must support the WAKE# function.
