Oscad: An open source EDA tool for circuit design, simulation, analysis and PCB design

Abstract

In this paper, we discuss the implementation of Open Source CAD (Oscad) [1], a complete EDA tool for Electronics and Electrical engineers. The paper illustrates the use of Oscad for circuit design, simulation and PCB design. It also gives implementation details of an in-house developed circuit simulator, Scilab based Mini Circuit Simulator (SMCSim), available in Oscad. The simulator can provide the system of equations for the circuit under test. This feature is unique to Oscad. The paper presents two examples to show the capabilities of Oscad.
