Redundant "Larry" VCCs and other connections about netlistsvg

[nturley]

This might be an issue I've seen before. If you look at the first screenshot on the readme you'll see there's a redundant line to count_out. It's due to the way that ELK doesn't really handle hyper edges.

I probably made it even worse when I added "lateral port" handling a while back.

I'll need to add a step to search for these redundant wires and delete it down to the minimum number required to connect all of the ports.

Are you setting postCompaction now? #40 (comment)

I need to write up a document of all of the types of bad layouts.

I think ELK is tracking this issue here: eclipse/elk#374

I just added postCompaction the other day but it probably won't help with this particular issue.

Here's the latest output (pulled a few hours ago) for my schematic: https://google.github.io/pcbdl/examples/servo_micro.svg

You can still see the same problem around U7 and U3.

postCompaction did make a lot of things shorter, I like that.

It looks like youd benefit from wide nodes on multiple layers. We should try turning that on the analog skin as well. https://www.eclipse.org/elk/reference/options/org-eclipse-elk-layered-layering-widenodesonmultiplelayers.html

I feel like I'm doing something wrong when trying to enable this.

It has no effect. But to be fair, even if I had typos it wouldn't complain about it

odd, I would've thought that would do something more interesting from the description.

I can only assume I didn't enable it properly.
