Design and Implemetation of Combinational Logic Circuits using Open Source Tool

Digital Systems plays an important role in today’s modern technology. The practical implementation of digital circuits in laboratories leads to a complex wired circuits and testing finds difficult. The damage of ICs, breadboards due to complexity needs replacement. This paper disseminates the virtual use of all the components using an open source tool. Digital circuits are of combinational logic circuits and sequential circuits. Implementation of combinational circuits using logic gates in virtual mode is described. Autodesk Tinkercad is an open-source software tool for the development of system. The design of combinational circuits such as Adder, Subtractor, Encoder, Decoder, Code converters are implemented with ICs using Tinkercad tool.
