Hello everyone! I'm a student in electronic engineering. We spend a lot of time solving differential equations, finding Fourier series and so on, but we are not learning very much about Computer Aided Design (CAD). My question is what software is being used for systems design in the "real world" (wherever that is :)? I'm interested in everything about the design, system emulation of any kind (There must be something else than Pspice?), the transformation from schematic to PCB layout, etc. I also wanted to know if there is a universal standard or recommendation about how to set up schematics for a large system. Thank you for taking the time to read this.
