Devlog #10

Since the last devlog, the simulator has gone from explaining things to letting you play with them.

First, you can now compare runs. Every time you solve, the curve stays on the plot, so you can change one thing and see exactly what moved. The diode also got live sliders. Drag the doping or voltage and the answer updates while you drag. The 2D devices like the MOSFET are too slow for that, so I added a quick mode that uses a rougher grid. It’s a little less accurate, and I wrote down exactly how much.

Then I built five guided lessons: a diode sitting at rest, a diode with voltage on it, a MOS capacitor, a transistor turning on, and what goes wrong when transistors get really small. Each lesson walks you through experiments step by step. The important part is that every claim a lesson makes is checked by a test against the solver I developed as part of the project. For example: if a lesson says “the current goes up,” a test runs it and makes sure it actually does.

The biggest addition is a device builder. You stack layers of doped silicon however you want, and the simulator solves whatever you made. You can also save a design and load it again later.

I agree I used AI for the frontend but I did not go VERY heavy on it. Only to build upon the frontend base I coded
