Circuit Tree is an automation engine that autonomously designs a circuit board design with given user inputs. Using Components define as proprietary models in its database it creates schematic, component placement and routing on the fly. This means that the automation engine auto selects various types of components for a circuit and knows where to place and route these components on board.
Circuit Tree design engine has been designed by engineers who have experience of more than 20 years designing all types of first time right designs.
