Abstract
A cell library database includes function information of standard cells which are basic circuits forming a logical device, each of the standard cell comprising at least one of power supply terminal as logical terminals, the function information of the standard cell containing logical information or delay information of the power supply terminal relative to an output terminal, or function information of macro cells which are functional circuits forming a logical device, each of the macro cell comprising at least one of power supply terminals as logical terminals, the function information of the macro cell containing logical information or delay information of said power supply terminals relative to an output terminal. A design aiding system uses the cell library database to execute logical simulation, etc.
