Greetings,

Yes, I know this is = old technology, but I have a project which I intend to use wire-wrap = technology to make a test breadboard. I tried the existing gnetlist = backends to see if one is already there, but there is not. All of them = produce a variation of:

netname node1 node2 = node3 node4...

What I am looking for is:

netname node1 node2, node3 node4, node2 = node3...

This is a wire chain where node1 = to node2 and node3 to node4 are on the first (lower) level, and node2 to = node3 is on the second (upper) level.

Does = anyone have such a backend or can point me to one?
