To design any electrical circuit, either [[Analogue electronics|analog]] or [[Digital circuit|digital]], [[Electrical engineering|electrical engineers]] need to be able to predict the voltages and currents at all places within the circuit.  Simple [[linear circuit]]s can be analyzed by hand using [[Complex number|complex number theory]]. In more complex cases the circuit may be analyzed with specialized [[computer program]]s or estimation techniques such as the piecewise-linear model.

Circuit simulation software, such as [[HSPICE]] (an analog circuit simulator),<ref>{{Cite web|url=https://web.stanford.edu/class/ee133/spice/HSpice.pdf|title=HSPICE|date=1999|website=HSpice|publisher=Stanford University, Electrical Engineering Department}}</ref> and languages such as [[VHDL-AMS]] and [[verilog-AMS]] allow engineers to design circuits without the time, cost and risk of error involved in building circuit prototypes.
