That seems reasonable to me, but what would you recommend me for the power supply section? Some DC/DC Converters that you have used already? I understand that ripple must be minimized and the power-up sequence it's important, also that EP2C120 requires 1.2V for internal power and its PLL and finally 1.8V and 2.5V for its I/O banks.
Thanks a lot for your help

Have a look at the power analysis tool, if you plug in rough values for your design it'll tell you how much current each power rail requires.
I usually use a switcher for VccInt then linear regulators or switchers depending on the board VccIO requirement.
The power up sequence isn't important as far as I know (as long as the supplies come up fairly qickly).
You'll end up having to read a lot of the documentation I'm afraid!
