I've just started working with VIVID 1.3 from MCNC and would like to
import .CIF files for editing and further work. It seems that my
version can only read .CIF into a compacted mask-layout display via
LLAMA. Are there any utilities that can take a LLAMA display and
translate it into ABCD (A Better Circuit Description)?

I wanted to do this a couple of years ago, for the same reasons you do. I called MCNC and asked them about doing it and they said, "Why would you want to do that?" I tried to explain but they didn't think it was such a good idea. I personally think Vivid is a great CAD system but the rest of the world (read marketplace) didn't agree with me. MCNC has dropped support for Vivid, they said there will never be a version 1.4 or 2.x. This is really too bad, but under the circumstances I can't see putting effort into something that's not going anywhere. /Al Thompson

This would allow designs done for one process to be converted to another process by recompacting the symbolic version using a new set of rules. Unfortunately, due to "conflicting priorities", we never got around to implementing it here at MCNC. I, too, would be interested in knowing if others have done this and, if so, how it worked out in practice.
