Every electronic device is constructed using one or more Printed Circuit Board (PCB). Different electronic components such as transistors, registers, capacitors, Integrated Circuits (ICs) etc. are mounted on conductive tracks or pads to form PCB. Previously, PCBs were designed manually, but as the complexity of the electronic devices has increased, the need for more sophisticated PCB design automation software arises. PCB design software is a kind of electronic design automation (EDA) tool. It is used to design layout of circuit. PCB design software not only provides visualization of the circuit but also verifies the working of circuit. This software significantly increases productivity and accuracy of the PCB due to elimination of manual intervention on complex PCB design process. PCB design software plays a very significant role in development of semiconductor industry. PCB design software is used for designing and subsequently manufacturing of automotive electronic devices, industry control systems, building automation, advanced medical electronic devices, communication systems.
