A circuit design aiding apparatus includes a circuit data storage that stores circuit data for each circuit diagram, the circuit data containing elements in a circuit, connection between the elements, and links to constraints, a constraint data storage that stores constraint data representing design constraints, a circuit edit controller that receives and edits the circuit data through user's operation and holds an element having been edited, a constraint edit controller that receives and edits the constraint data through user's operation, a constraint updater that updates, when the circuit data is edited, the constraint data set to the edited element based on the type of the constraint and the type of the edited element, a display unit that displays the circuit data and other information, and an output data generator 15 that generates circuit data and other data to be outputted.
