SOPC bugs

Hi, 

 

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! 

 

Cheers
