Aurora Circuit Studio: Professional Circuit Design, Finally in the Browser

A founder deep-dive into Aurora Circuit Studio — a browser-native EDA workspace unifying schematic capture, PCB layout with push-shove auto-routing, ngspice-in-WebAssembly simulation, 3D preview, and Gerber/IPC-2581 fabrication export. With analytic Hammerstad–Jensen impedance from stackup, 32 DRC providers, and a parts catalog architected for millions.
