SOPC Builder exports internal IO pins

Hi 

I added serval IPs in sopc file, it passes SOPC builder. But it exports many interanl IO connection pins. Then it fails Analysis due to exceeding available IOs on the chip.  

Why and how to prevent those internal pins from exporting? 

Thank you, 

david

What version of the tools are you using, what are the signals called, and which components are they coming from? 

 

If these signals are supposed to be exported to the top and you are just doing some benchmarking and running out of I/O you can either assign those signals to virtual I/O or create a top level wrapper where you only connect the I/O you want to hit the pins and leave the rest internally connected/no connects.
