General Description:
When I attempt to create a core using CORE Generator, an error of the following type is reported:

Solution

Look in the specified directory to verify that the files are missing.

If this problem is seen with respect to a module that is part of a newly installed IP update, try reinstalling the update as follows:

1. Extract the IP update archive into a temporary directory.

2. Copy the newly extracted file structure into the Foundation directory (e.g., C:\Fndtn) or top-level Xilinx directory (e.g., C:\XILINX).

Problems of this nature have been encountered in the past with newer versions of the UNZIP software on UNIX platforms. For additional information, please see (Xilinx Answer 7711).
