ParHelpers:360 - Design is not completely routed.

I am using a DDR2 core in a Spartan6 with ISE 14.7  and get this error during PAR:

 

WARNING:ParHelpers:360 - Design is not completely routed.

DDR2_inst/memc5_wrapper_inst/memc5_mcb_raw_wrapper_inst/ioi_drp_clk_c

 

When I open the .ncd file, I can see the unrouted net, but how do I fix this?

Can you show the schematic (source and load) of failing net?

This is not the info that we need for debug the issue.

The FPGA Editor screenshot dosen't show what the startpoint and the endpoint of the unrouted net are.

You can check the net in the technology schematic in ISE or the schematic in Planhead.

The Schematic will tell you clearly what the startpoint and endpoint are.

And that would help to analyze why the net is unroutable.
