10.1 Chipscope iBERT Core generator - When generating an iBERT core a "ERROR:NgdBuild:28 - Top-level input design file..." message appears


When generating an iBERT core the following message appears:

"ERROR:NgdBuild:28 - Top-level input design file "<Filepath>data.ngo" cannot be found or created. Please make sure the source file exists and is of a recognized netlist format (e.g., ngo, ngc, edif, edn, or edf)."


This issue occurs when attempting to generate an iBERT core in a directory with a path name that contains a space or spaces. To work around this issue, generate the iBERT core in a directory without spaces in the path name.
