fpga board push button questions

I just wanted to clarify: does pushing the button correspond to a single pulse? And is the default state of the button a logical 0, and when pushed is it a logical 1?

I doubt the button is de-bounced. As for the logic levels, you need to look at the schematic of the board you're working with to see which logic level they are set to by default.
