Recognition of Hand-Drawn Circuits

by Ravi Palakodety and Vijay Shah

 

Abstract

This project will develop a tool for recognizing components, their values, and their connectivities from a hand-drawn circuit, and will use this knowledge to generate a primitive SPICE netlist. The user will draw his circuit on an 8x8 grid, with each component centered and sized to fill the block. The user¡¯s available components include resistors, capacitors, transistors, voltage sources, power supplies, ground terminals, and connectivity nodes. We will display the original hand-drawn circuit, a circuit with hand-drawn components replaced by computer generated pictures of components, and the text of the SPICE netlist onto the screen.
