That's when we move over to block diagrams. Not just for chip designs,
also for large board level designs.

They will be messed up upon renumbering. But who knows, someday it might

Didn't draw a line, but I am not a programmer. Sure, I could figure it
out and somehow attempt to fix it but there are people in this community
who could do that a lot better. Anyhow, I've mentioned further above in
this thread what the problem is (renumbering messes up refdeses when
only slot A has power visible). For me the solution right now is to just
stick with my old CAD. Or maybe even resurrect ye olde OrCad. Somehow I
often miss that old SDT, probably just like I'd wish I could have my
first car back just one more time :-)
