eSim Alternatives

eSim

eSim (previously known as Oscad / FreeEDA) is an open source EDA tool for circuit design, simulation, analysis and PCB design. It is an integrated tool built using open source software such as KiCad and Ngspice . eSim is released under GPL.

eSim offers similar capabilities and ease of use as any equivalent proprietary software for schematic creation, simulation and PCB design, without having to pay a huge amount of money to procure licenses. Hence it can be an affordable alternative to educational institutions and SMEs. It can serve as an alternative to commercially available/ licensed software tools like OrCAD, Xpedition and HSPICE.

Draw circuits using KiCad, create a netlist and simulate using Ngspice.
Do PCB design and generate Gerber files using KiCad.
Add/Edit device models and subcircuits using the Model Builder and Subcircuit Builder tools.
