I like to download the Kicad source and occasionally browse through it. This is partly because I’m trying to learn wxWidgets development and C++ in general. I came across mention of “Incremental connectivity” and an “Incremental Netlister”. Is this something new or has it been around for a while? Is it something to get excited about? Just curious. Thanks.
It is new for KiCad v8. It facilitates faster interaction with large-scale (thousands of nets) schematics. Most people will never notice the effects.
The realtime netlister, of which it is a part, was developed for KiCad v6. Most people do notice the difference between realtime netlisting an compiled-on-request netlisting. This is what enables bus unfolding, netlist hierarchy navigator and many other features.
