Hello,
The said error is the tools admitting to have optimized away logic, and then missing it at a later stage. With Xillybus, this typically happens when you've added a stream on the custom IP core, but not made any use of it in your application logic. Or even no reference.
In other words, you should also edit xillydemo.v/.vhd to relate to the new IP core and its streams. Note that there's an instantiation template in the bundle to make this easier.

Eli
