IP TOOL BENCH fail to generate all the files

[Altera_Forum]

when I use the IP tool bench to make a nco dds, the third step generate will stuck in "generating megacore function top-level", and there's no .qip files generated. 

Is there any solution to this problem? Do I make some mistakes

If the other files are generated, just add all the files nco_library and <ip_name>.vhd to your project instead of the QIP file.
