Re: gEDA-user: gcshem to magic

   OK
   So I am trying to generate a netlist for magic (I know this is not
   quite gEDA), but I can't find any documentation on magic's netlist
   format.  Does anyone know what the format is.
   It looks like it a net follows this format
   [instance]/[port]
   [instance]/[port]
   [instance]/[port]
   But how do I create a new net.  Initially I thought it was a blank
   line, but the router appears to think these are all the same net.

   "gnetlist" is the tool for exporting netlists to other tools, using
   "back ends" for the specific export problem. It appears nobody has
   written a back end for magic. Back ends are not terribly difficult to
   write.
