6.1 / 6.2 EDK - "ERROR:Xflow:198 - Design system.ngc doesn't exist, or design extension is not valid"

Description

Keywords: EDK, XPS, ERROR, Xflow, Xflow, NGC, Alliance

Urgency: Standard

General Description:
When I run "Tools -> Generate Bitstream" in EDK, the following errors are issued:

"xflow.exe -wd implementation -p XC2VP7FG456-6 -implement fast_runtime.opt"
system.ngc
ERROR:Xflow:198 - Design system.ngc doesn't exist, or design extension is not valid.
ERROR:Xflow:11 - 1 error(s) found while processing cmdline arguments. Aborting flow ....
ERROR:Xflow:38 - Command Line errors... Aborting!
make: *** [implementation/system.bit] Error 1
Done."

Solution

These errors occur because ISE Alliance is installed, and this software does not include "xst.exe".

In order for EDK to complete the bitstream generation process, you must synthesize the "system.vhd" or "system.v" file with a third-party synthesis tool. Then, copy the resulting netlist to the "<project_directory>\implementation" directory.
