I'm receiving a strange warning in ISE for a Virtex 4. I've been seeing new warnings and infos using the new DCMs. Is it safe to ignore this warning in MAP? I couldn't find anything related in the knowledge base. This autocal appears to be generated for speed improvement?
Help is much appreciated.
Thanks,
