Is my understanding correct: the FDF specification only supports a maximum
of 64KB alignment for files (section 2.5.6), but the PI specification
supports (table 7), up to 16MB alignment. Or am I misreading it?

Thanks,

Tim

Udit,

As Marvin points out the [LibraryClasses] section of the INF file are going
to imply the order of the library constructor calls in the AutoGen

Worst case you can demote FpgaInterfaceInit () from being a constructor to
just being a public library function that the other lib can call explicitly
from its constructor. Maybe that is too drastic and you could must move a
function out of FpgaInterfaceInit () and make that function part of the
Public library interface?

Thanks,

Andrew Fish
