What is 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 icon KiCad and Ngspice icon 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.

FEATURES

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. Runs on Ubuntu Linux and Windows.
