Bridging the Gap Between PLECS and SPICE

3 years seems like a long time (though to be fair, I know spectre has been around for decades). Were there any particular challenges that made it difficult?

Cool! Does PLECS do any symbolic simplification for its equations? Without that step, we found it impossible to handle even the smallest examples for realtime audio circuit modeling.

Conversely, traditional SPICE simulators embody an inherently bottom-up approach

- its a lower down approach, but far from the bottom!

I know what SPICE is: https://en.wikipedia.org/wiki/SPICE

And apparently, this is PLECS: https://www.plexim.com/products/plecs

I did a double take at your name. Hello doppelganger!
