LVDS clock and data signals, interfacing to LVDS DAC

Yes, just the LVDS IO standard takes care of it for you. Much easier than instantiating primitives.

One thing I almost forgot is the altlvds megafunctions will just instantiate DDR if you use them in /2 SERDES. If your core clock rate is really /2 the data rate, i.e. ~370MHz, then it might be a problem. What I've done is generate the altlvds and say the SERDES is /4, and then just present the data to the transmitter 4 bits at a time, or read the data from the receiver with my own DDR implementation.
