What is the status of the GPIO pins at startup?

I am trying to learn FPGA protocols and in particular what happens during startup. I am learning about the Cyclone V by using the Deo Nano SoC. Between the time power is applied to the board and a file is loaded onto the FPGA, what are the states of the GPIO pins?

Hi Doug Kirven,

 

All the I/O are in tri-state mode during power up.
