Circuit recognition using netlist.

The existing software for circuit design and simulation require the user to be skilled either with good programming ability or ‘pick and paste’ model. To remove this barrier of programming knowledge, we propose a simulation model where a circuit drawn on a paper will be simulated. The circuit drawn on the paper will be fed to the computer using a scanner/camera. The image is de-noised and the nodes in the circuit are detected. All the characters, numbers and symbols alone are stored in a separate image which is used for optical character recognition. After node detection and character recognition, a netlist is compiled which is used for simulation. Applications of this simulation model include smart teaching systems, tablet app and with more research, a great deal of components including transistors and ICs can be simulated.
