A method for circuit design based on Artificial Intelligence (AI) and an implementation system thereof. Subcircuits of a circuit-design topology of a historical phase, which are of different categories, are classified and a first feature model are obtained by training; a feature parameter of a circuit is acquired, and finally, the circuit feature parameter is compared with an expected parameter and a corresponding determination result is obtained, thereby a determination is able to be provided for the circuit design, and no simulation is required. As a result, an adjustment on the circuit design or an optimization on the circuit can be performed at a proper time, accordingly, the efficiency in design can be improved.
