Hi,
I'm designing a pretty horrible board (33 page schematic!) that will use an Altera Arria II GX in the 572BGA package. There are 240 pure I/O pins in this package, and 12 dedicated clock pins. I'm getting close to using up all the i/o pins, and starting to do silly things to save a pin here and there. Don't blame me, blame customer feature creep!
So, is it possible to use clock pins as general-purpose inputs? The documentation doesn't say so, but it does imply somewhere that clock nets can be used for non-clock functions like async resets, so there should be some not-too-disgusting way to used them as slow static inputs.
Pity they didn't dual-purpose the clock pins. It's not often you need
12 clocks.Any thoughts/experience here?
Thanks
John
