ALTLVDS_RX->LVDS serdes Link Training

DPA is not supported in Cyclone V. I somewhat disagree with rsefton on how great DPA is. It is absolutely required for really high speeds, but it has the drawback that each lane does its own alignment, and so two lanes can be off from each other by a bit period or so. With regular LVDS you have to close timing, but once you do you know that each channel is aligned with the other channels, since the data is synchronously clocked in. What is your data rate? Assuming it's within the max LVDS rx data rate in the datasheet, you should be good to go. The altlvds block has really good timing numbers and should work with any device meant to run at that rate. The only thing you really need to watch out for is to make sure you know if the clock coming in is edge-aligned(in which case the altlvds will do a 90 degree phase shift on it to put it in the center of the data eye) or center aligned(in which case it doesn't do a shift and maintains that relationship, since it is already in the middle of the data eye). Otherwise it should work right out of the box.
