Get even a basic equation solver in there and I'll be a user! Have it handle units properly and I'll be a happy user. Have it be able to handle both worst-case and RSS tolerance stackups and I'll be in love.

Excited to hear it! Our language already captures tolerances and the solver we are building does proper tolerances stackups. You specify the desired output with a tolerance, eg my_regulator.power_out.voltage = 4.75V to 5.25V and we will solve the stack up to get you there. Hang tight, its coming soon!

  Will it take into account temperature ranges and other parameters as well?

    If we can build the equation solver our hearts are set on, you should be able to account for as many factors as your design requires - albeit with some performance limitations at some point. That is, assuming temperature can be factored into equations in the same manner as any other parameter or attribute

We're also super stoked about getting topology and equations together in the same file (and even code-base!) The equation solver is soon on our roadmap: https://atopile.io/roadmap/#language-features https://atopile.io/roadmap/#language-features

  Solvespace has a nonlinear algebraic equation solver: https://solvespace.com/index.pl https://solvespace.com/index.pl It's what underlies the geometric constraint solver which you don't need for what you're doing. It's probably worth a look under the hood. You might also read this post from Michael-F-Bryan implementing something similar in Rust: https://users.rust-lang.org/t/geometric-constraint-solvers-part-1-algebraic-expressions/45818 https://users.rust-lang.org/t/geometric-constraint-solvers-p... He based his work on what he learned from Solvespace.

    Thanks for sharing! We will have a look
