Hi @ivanfan,

 

The error is saying that the full bus can not be placed within the same ILA because some of the signals require different routing. Specifically, some of the signals are clocks that need to be buffered before they are connected to an ILA.

You can try expanding the bus using the "+" and selecting some of the signals which do not require a buffer.

 

Alternatively, you can add an ILA inside of the MIPI core after the signals are buffered. This will require adding the ILA post-synthesis and not directly in IPI.

 

Don't forget to reply, kudo, and accept as solution.

Hi @ivanfan 

 

It is not directly able to connect it.

However, I guess you measure these signals via VIO...
