Method and software for automatically designing IC layout

摘要

A method and software for automatically designing IC layout can be used in the two phases of IC circuit design-and-layout and the circuit simulation. Users can assign all or the partial end points of the devices in the integrated circuit to connect plural metal layers by this manner of automatic layout. In such a way, it is only necessary to make the connection lines connect the end points in the certain metal layers without connecting to the first metal layer. Moreover, circuit modification can be achieved more easily and time and cost saving
