Hi All - During implementation of the design with ILA core netlist insertion, I ran into this "unknown error". I am not sure how to go about resolving this issue, since it is unknown. Any ideas or suggestions would be very much appreciated.
Opt Design:
[Chipscope 16-119] Implementing debug core dbg_hub failed.
ERROR: An unknown error has occured while implementing debug cores in this design.
Thank you!

Many thanks Vinay and Vijay both for your ideas and suggestions, I had resolved the issue.
With the initial problem of long path directory under window, I copied the design folder another folder under C to make the directory path shorter. In stead of copying the design folder, I should have File --> Archive Project. By Archive Project, the "unknown error" has gone away.
Thanks,
Howard

Hi Howard,
If you are using windows, reduce the directory path length and give a try.
Thanks,

Hi Vinay and Vijay:
Thank you for your feedback.
I am using window 8, and initially I had the problem of a directory path length, as Vinay has suggested. I then copy the project to a different folder right under C directory, to make the path shorter. I then ran into this "unknown error".
If nothing else, I will try Vijay's suggestion of creating a new project.
Thanks,
Howard

Hi,
The issue may occur if the Debug Hub in cache is out-of-sync and needs to be cleared with the following command.
update_ip_catalog clear_ip_cache
Can you try running the above command and check whether it helps?

Is this a valid command? It fails to run at my end.
update_ip_catalog clear_ip_cache
Also regarding the failure above with "unknown error", using all the suggested solution above did not help. The problem got resolved when I added the header file "`include "cs_ver_inc.v"" to the top level design.
