Another up-and-coming solution is Julia's simulation ecosystem [1]. It is powered by the commercial organization behind the Julia programming language, which has received DARPA funding [2] to build out these tools. This ecosystem unifies researchers in numerical methods [3], scalable compute, and domain experts in modeling engineering systems (electrical, mechanical, etc.) I believe this is where simulation is headed.

JuliaSim looks interesting! From my understanding, it's 100% proprietary/commercial, but built on top of the open source https://github.com/SciML/ModelingToolkit.jl?

I believe it's open source but requires a commercial license; free for academics.

To be slightly more precise, it's not open source, but source available.

"Another up-and-coming solution is Julia's simulation ecosystem"

Still not comparable with Modelica that has proper specification, including graphical representation of models.

JuliaSim does have graphical representation, a GUI and an IDE. But, granted, it is also a commercial product, not open source.

But this representation is exclusive to JuliaSim, is it not? MTK package didn't have equivalents of Dialog, Icon and Diagram annotations the last time I checked.

It is exclusive to JuliaSim. But the tools generate MTK compatible component models so, once built, they can be used with MTK.

There' s a Chinese company also using Julia and Modelica https://www.tongyuan.cc/product/MWorks . They have projects like https://github.com/Suzhou-Tongyuan/syslab-deploy using https://discourse.julialang.org/t/syslabcc-suzhou-tongyuans-... .
