• TLDR: Full wave solvers, inductance extraction, RF IC design. Big gap needs urgent filling. • Other types of analysis - harmonic balance, transient noise, periodic steady state. They exist but we don’t know how reliable they are.

so anything else?

Good scope viewers. The existing ones are terrible

Openlane is pretty clueless about doing analog routing, meaning that all top-level routing of analog components has to be done by hand if you want your analog circuit to actually work right. I do not know if this is a limitation of openlane or of OpenROAD, but I suspect it's just openlane. The DEF file format supports all sorts of analog routing features like non-minimum-size routes, shielded routes, etc.; although the router also needs to know things like how to make sure there isn't any significant I-R drop near analog components, that analog components are not placed near digital noise sources, and that analog signal lines are kept away from digital clock signals or other digital noise sources, etc., etc. In principle, one would prefer not to hand-route the top level, and routing tools should be able to treat all the analog requirements as just another optimization problem, and if everything is well-specified, the automated tools ought to be able to do a better job of it.
