Astroboy,

I think your list is valuable!

Regarding:

"7. Select minimum IO drive strength required for your application. The default drive strength used by Quartus for all IO standards is set to maximum (for everything pre-65nm) – this is ideal for IO timing, but not necessarily for power and SSN. This is highly design dependent and the maximum setting maybe ideal for your application"

I've always asked myself why Altera's default is max dirve strength!!

By the way this is one of the 1st warning given for HardCopyII migrations.

I would like to ask you if you are aware of a default change in 65nm.

Thanks

Cheers
