Couple of problems just offhand.
* src_sid is a one-per-input signal. See noc_shell.v for details.
* Settings buses and readback buses are one-per (max(input, output)).
Again, see noc_shell.v. I don't think this is a problem for you, though.
You should be getting errors in simulation (or warnings in synthesis) right
now. Look very carefully through these warnings to see which signals are
undriven. My guess is src_sid is undriven on the top 16 bits and so you
can't set src_sid correctly for input 1.
