In the ChipScope Core Inserter flow, the CORE Generator tool fails to generate the ICON core during Translate process. The following error messages appear in the console:
<CoreGen>:WARNING:sim:882 - The working directory path for this project is very long (>160
<CoreGen>:WARNING:coreutil - XST failed for icon_pro.
<CoreGen>:ERROR:sim - Error found during generation.

According to the error messages above, the failure occurred during Synthesis process (XST).
There is an xst log file located in folder:

The following error messages are seen at the end of the log file.

For technical support on this issue, please open a WebCase with this project attached at http://www.xilinx.com/support.
Windows has a 260-character limit on path lengths. When the Debug Core is inserted in a project path greater that 160 characters, the extra hierarchy required for the generation ccauses the complete path to exceed 260 characters.
Some ways to work around this issue:
In the ISE14.3 design tools, the internal path of the Debug cores have been decreased to allow a longer path for the project directory.
