SOPC bugs

Honored Contributor II



I keep running into a little problem with SOPC builder producing the following Error! 


no slave id! 


at the  

Making arbitration and system (top) modules. 

stage of generation 


I start with a simple design, as follows 

1 interface to user logic.. an AHB master port. 

1 AHB to avalon bridge 

1 SDRAM controller 


I can build this design.. with the interface to user logic connected my external logic.. and it works great. 


but when I add a nios2f and some internal SRAM.. 

I get the error above? 


If I delete the nios2 and sram... (ie back to where I started.) 

I still get the error above... 


Any clues as to why and what to do would be of great use!
