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 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.
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.
