use of megafunction ALTGX

Hello,

I'm working with Quartus 10.1,

I want to creat a ALTGX function, but I can't choose this. It stands in grey.

Does someone know what I can do, so I can use this function?

It's for creating a SERDES.

Best regards

    No: ALTGX infer a physical object of the FPGA.

    Not all FPGA have this features.

    It's not VHDL that will be syntetized.

    It's not true.

    AltGX shall be on Cyclone IV and all stratix GX family and Arria Family (and maybe someone else I've forgot to mention)

    We can simulate a ALTGX function that is made by someone else,

    but we can't make an own function with this...

    Because of we don't have to right libs or something like that?

    What device family are you targeting? The ALTGX MegaFunction is only for Cyclone IV and Stratix IV I believe. Anyway, if your looking to implement a SERDES, then you most likely want to use ALTLVDS_RX and/or ALTLVDS_TX.
