I am looking for a few pointers on how to get started with interfacing a 10bit parallel DAC (http://www.farnell.com/datasheets/2258690.pdf?_ga=2.122444303.541138324.1501226629-2134010037.1500388166) with my Nexys Video board from Digilent.
Should this be done with a state machine?

This could get tricky if you're trying to run at the full rated 240 MHz. According to the data sheet, you need 1.5 ns setup and 2.5 ns hold and the clock cycle time is only 4.1666 ns. That means the window to hit for data transition is only about 166 ps. At much lower speeds, it should be relatively straightforward, though. How fast were you going to run the DAC?
