Hi, I don't want to discuss about windows versus linux. I use the both in my job and linux at home. For electronic design under Linux I use a capture, PCB software call Kicad (also works under windows) Designed and written by Jean-Pierre Charras, a researcher at LIS (Laboratoire des Images et des Signaux) and a teacher in IUT de Saint Martin d'Hères.(France), in the field of electrical engineering and image processing. Kicad is a set of four softwares and a project manager: * Eeschema: Schematic entry. * Pcbnew: Board editor. * Gerbview: GERBER viewer (photoplotter documents). * Cvpcb: footprint selector for components used in the circuit design. * Kicad: project manager. http://www.lis.inpg.fr/realise_au_lis/kicad/ For the simulation Kicad can generate a netlist for spice softwares. I use gspiceui with ngspice an gnucap. Best regards, Lannick
