Abstract

Disclosed are a method, system, and computer program product for providing customizable information in designing electronic circuits with electrical awareness. The method or the system displays a portion of a physical design of an electronic circuit in a first display area. The method or the system receives or identifies a user'"'"'s or a system'"'"'s manipulation of the portion of the physical design of the electronic circuit. The method or the system then determines and displays an in situ response to the manipulation in the first display area. The method or the system may further display, in the first display area or in another display area, result(s) relating to the physical data of a component, electrical parasitic(s) associated with the physical data, electrical characteristic(s) associated with the physical data or the electrical characteristic(s), or other element(s) of the physical design that is impacted by the manipulation.
