14.2 XST - "ERROR:Xst:2647 - Failed to run core generator for
In designs containing TeMAC cores,the following error occurs during synthesis:
ERROR:Xst:2647 - Failed to run core generator for <hard_ethernet_mac_wrapper_fifo_generator_v4_3_1> macro. ERROR:EDK - xst: unknown error occurred. ERROR:EDK:546 - Aborting XST flow execution!
How can I fix this?
You can try the following:
Ensure that the Xilinx ISE and EDK environment variables are set correctly.
Decrease the path length of the project as there are some issues with XST and path lengths that exceed 256 characters.
Make sure that the path does not contain spaces or unusual characters.
Ensure that the CORE Generator tool has sufficient virtual memory (Launch CORE Generator, File -> Preferences; under the Java tab, increase the memory here).
Make sure that the regional settings on your machine are set to English (US).
Ensure that any Virus scanners on the system are disabled.
