Abstract: An integrated circuit (IC) is designed by generating a circuit diagram of the IC using one or more blocks. An information repository is provided that contains layout information that is associated with one or more template blocks. A symbol layout abstraction model is then generated by associating the layout information that is associated with one or more of the template blocks with at least one of the circuit diagram blocks of the IC.

Abstract: An integrated device for selectively generating calling vibrations or calling sounds in cellular or pager phones is disclosed. In the device, two vibration members are set in the upper and lower portions of a casing, respectively. The two vibration members respectively respond to low and high frequencies applied from the PCB of a phone to the coil of an electromagnet, thus generating calling vibrations and calling sounds. The device thus selectively generates calling vibrations or calling sounds in accordance with a selected mode. The device of this invention has a simple construction with a reduced number of elements, thus simplifying the production process and reducing the production cost of cellular or pager phones. The device also accomplishes the recent trend of compactness, thinness and lightness of such phones.

Abstract: An integrated device, used for selectively generating waking vibrations or sounds in alarm watches or in communications equipment such as cellullar or pager phones, is disclosed. In the device, first and second vibration members are set in a ring case and respectively generate waking vibrations and waking sounds. The second vibration member is made of a synthetic resin film, with two inner terminals being connected to both ends of a coil. A lead panel integrally extends from the edge of the second vibration member, thus being exposed to the outside of the device. Two outer terminals are provided on the outside end of the lead panel and are connected to the inner terminals through copper wires, thus connecting the coil to a PCB. The second vibration member, originally used for generating waking sounds, is thus used as a circuit board for the coil.
