ALTLVDS_RX megafunction

Hi, guys: when i build a new project with HDL and megafunction , I use the ALTLVDS_RX for adc data(8 channels and deserialization factor is 1) and it works . Now, I want to generate a system i...

So, you mean that an Avalon-ST component and a SG-DMA will be ok, and I don't need a altlvds_rx block(.bsf) in my top-level .bdf file. Is it all right?

How do you interface to your ADC at the moment? Are you interfacing using LVDS pin constraints and then using DDR registers with a 200MHz clock, or are you using a SERDES (altlvds_rx) component? Either way, you can create an Avalon-ST component that includes that logic. You really need to start moving away from .bsf and learn a hardware description language. It'll make this sort of design significantly easier.

Cheers,
