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?
