Ngspice Gui. All experiments described here require using at least kicad version 5 and have been done with a ms windows nightly. Such a circuit may comprise of jfets bipolar and mos transistors passive elements like r l or c diodes transmission lines and other devices all interconnected in a netlist.
It is offered together with 32 bit ngspice 27. Ngspice is the open source successor of the venerable spice3f5 from uc at berkeley. Qucs s qucs with spice is a qucs subproject using free spice circuit simulation kernels ngspice recommended with the qucs gui.
Spicecircuit is a is a full graphical circuit entry and simulation application for ms windows.
Time varying currents and voltages are simulated as well as noise and small signal behavior. Time varying currents and voltages are simulated as well as noise and small signal behavior. It supports waveform math copying to clipboard and saving. Unlike popular circuit sim ulators such as ltspice that are capable of drawing symbolic objects schematic captures to de scribe circuit topology ngspice simulated circuits are described as text only inside a file called a netlist.
