Plus, there is a large community dedicated LTSpice users who support the product and enhance it in many ways. [spice = simulation program with integrated circuit emphasis; qucs = quite universal circuit simulator] 1.1 Installing LTspice LTSpice is built for Windows and Mac. The only time it is worthwhile to use LTspice is when you are doing (as the name implies) you are using parts from linear to do switchmode power supply design, since they have specialized macromodels for their parts that reduce simulation time by orders of magnitude. I also recommend QUCS for simulation. In-fact you should ENHANCE LTSpice to include the likes of ADI & Hittite product models (where it makes sense of-course). That’s another thing I wanted for a long time but haven’t actually checked on for a while. Then qucsator fails to keep the ports connected when flattening the netlist.
