OPB<-> WISHBONE wrapper

wishbone wrapper

I got this IP from opencores and i'm trying to use it ..The doc says how to install it and that's all ..Yes is now visible and i can instantiate it under EDK .But when i generate the netlist it gives me an error :
implementation/pp405_0_wrapper.ngc error
i remove the opb-woshbonw ip and all now works .
any idea why i get such an error????

wishbone opb

OK nobody answered .. so i dropped this opencore's core .. i spent a day trying to figure out what whas wrong ,and why i got such an error ! .Couldn't figure it out.
But i found the sources of an equivalent bridge core between a OPB bus to Wishbone and viceversa ..
Here is my great find : **broken link removed**
