[Xcircuit-dev] Cadence DFII to XCircuit translator

How does dbWriteSkill compare to exporting EDIF?  I was considering
the approach by writing an EDIF-to-xcircuit converter, mainly because
doing anything with Skill code in Cadence requires a license (which I
have now, but that's not a solution for everyone, obviously).  Or is
step 2 somehow easier than taking an EDIF parser (there's a decent one
available in open source) and writing convert-to-xcircuit routines
into it?

The general principle of generating input for xcircuit via Tcl commands
is sound.  I have done it before.  The commands for generating elements
in xcircuit are not used by the GUI, however, and tend to be rather
obscure.
