This guide would be a low level intro to the tools offered by the FEL, targeted for an audience that frequent a high school, a professional school, or Technical schools in Electrics (e.g. Istituti professionali in Italy). As there are already many good manuals online that explain the various tools, the goal is to explain in a compendium what do the various tools, how to use them using the GUI or the terminal command, when it can offer more configuration/setting options, with simple examples. It is organized in two parts: a first section dedicated to analog/digital electronic with discrete components, the other to integrated electronic (VLSI and Nano). I'll focuse principally on the first part.
