In a routing method, an initial chip layout and routing planning information corresponding to the initial chip layout are obtained. The routing planning information includes planning information of a first site in the initial chip layout. The planning information indicates a location region, a routing orientation, and a predefined connection path. A first end of the predefined connection path is connected to the first site. According to the location region and the routing orientation, a first route segment connecting a second site of the initial chip layout and a second end of the predefined connection path is determined. According to the predefined connection path, a second route segment connecting the second end of the predefined connection path and the first site is determined. According to the first route segment and the second route segment, a connection route between the second site and the first site is generated.
