What alternative we have to LPM_ADD_SUB for Arria10 device. I want to use carry chain logic to use it as delay element. Looks like LPM_ADD_SUB is not supported for Arria 10 device. Please advise.

I need to use the carry chain logic. per the notes Arria10 does not support LPM_ADD_SUB. the example you posted says it will use LPM_ADD_SUB.
