Hi,

By "locked down" I mean that the IP I am using requires the subsystem to match exactly to the documentation; I do have full access to how the buses are hooked up. The NIOS II code for that CPU/subsystem is pre-compiled (communications stack) and I am only provided the image, thus the QSYS must match exactly.
