I started using gEDA as schematic capture for ngspice (in 2002, maybe). Then, I found that gnetlist back ends were simple scripts. I could thus use it to export netlists to PH70, an obscure layout program from Lincoln Labs used by a layout contractor popular in MIT-associated circles. I did several projects with that flow. From there I moved to ASIC design (for Osaka University), exporting SPICE for both simulation and layout. The PH70 contractor retired, and the MIT business transitioned to Osmond PCB for layout, done in-house at MIT. Some of that then switched to layout contractors using Allegro and PADS. This went amazingly smoothly from my perspective, although if I had been LISP-phobic it wouldn’t have worked.

gEDA is powerful and versatile!
