General Purpose I/O Pin Names

We intend to use the CycloneIII for a project, and we need to generate high frequency signals from 0 to 5 volts. Can the FPGA produce a signal that goes up to 5 volts and has a rise time of about 200...

Also, is there anyway to find exactly what pins are general purpose i/o? I have found only a few mentions to D0, D1, D2..etc pins, but I cannot find whether or not they are GPIO or not.

There is two ways;

1) On the handbook page, there is a link to pinout files. Those files list all the pin features.

2) Create a project in Quartus and select the device you want to use. Open the pin planner and its a GUI with all the pin types.

Cheers,
