Using Digilent analog shield on DUE and mega2560 ?

I need the speed and memory of the DUE board but the analog shield appears to only work on Uno. The Library shows it is supposed to work with Due but says that was not tested.

Anyone successful using this shield on DUE or mega2560?

From the schematic: https://reference.digilentinc.com/_media/analogshield_sch_rev_d.pdf it looks like the ADC and DAC both use the SPI interface through the ICSP header. The shield also uses pins 3, 4, 6, and 7. I think this means that the shield will work on the Mega, DUE, ZERO and other boards that have the ICSP header in the same place as the UNO.

Agreed, I see no reason why it should not work. The library code looks like provisions have been made for DUE (but not tested as in one comment line)

It works fine on UNO but no joy on either DUE or mega2560. I suspect library software error.
