Dear Sir,
The reference design is a firmware (stellarIP) and a software (visual studio). The files I was referring, ie sipif.cpp. to are in the software package.
What I also said is that the firmware as a standalone entity is not going to operate. The software is configuring all the integrated circuit on the board through the firmware during run time.
Look at the SD128 document, the FMC112 star document, chapter 5, the AD9517 is mapped between address 0x300 and 0x532 and the software configure the chip in the source file fmc116_clocktree.cpp. The communication goes through a mac_engine or a host interface star.
Note that the software is generic, it should have been named FMC11x initially because it is same for both FMC112 and FMC116.
I hope that helps!
Best Regards,
Arnaud
