# Program for simulating circuits on linux

Do you know any program that works on linux and can simulate complex circuits?

What do you mean for complex circuits? –  Daniel Grillo Apr 1 '11 at 14:06
This is possibly duplicated with What are the freeware SPICE simulators available? –  Daniel Grillo Apr 1 '11 at 14:31
@oneat - Do you need complex digital simulation as well as analog (Through Verilog AMS or VHDL-AMS), or would you prefer a schematic based simulator? –  Kevin Vermeer Apr 1 '11 at 14:31
@reemrevnivek, I can't understand. SPICE means Simulation Program with Integrated Circuit Emphasis. Why Simulation ≠ SPICE? –  Daniel Grillo Apr 1 '11 at 14:39
@Daniel - Mathematically, SPICE $\subset$ Simulation. In prose, there are a wide variety of circuit simulators available, and SPICE is just one of the most popular simulator frameworks. –  Kevin Vermeer Apr 1 '11 at 15:47

The gEDA project supports the Icarus Verilog (digital only, though Verilog-AMS support is planned), GTK Wave, ngSpice, and Gnucap simulators. It has the advantage that you can compose your schematics, simulations, and PCBs in the same flow, instead of having to manually copy everything from your schematic editor into the simulator.

If you want to evaluate more options, the Wikipedia comparison of EDA software, Electronic circuit simulation, and list of free (as in freedom) simulators pages all contain useful links.
