Route error of PlanAhead

I use PlanAhead with ISE to do the optimization of placement and route. I meet this error.

 

ERROR:Route:491 - Found unroutable pin on net
   <mb_6/mb_6/Performance.Data_Flow_I/exception_registers_I1/FPGA_Target.Gen_Ret_Addr[25].MUXCY_I/O>.

 

 

I look for this pin in the primitives and nets of mb_6, but I can't find it.

 

Thanks a lot!

This seems like it might be a generated net name.

 

  •  Try to open the post PAR NCD in FPGA Editor.  
  • Search for the net name given in the error
  • Select the Net and identify which portions of the net are unrouted.  Hopefully this will help identify the reason why it is not possible to route.

But the FPGA editor says it can't find it...

 

And I can't find it in the primitives and nets of PlanAhead.
