Patent number: 6701502Abstract: After the name of a signal line is entered, cells are arranged and, a channel to be wired therein is generated. After the completion of global wiring and minute wiring, a compaction process is performed. Here, the transistor density TD of an integrated circuit device to which the compaction process has been executed is compared with a standard value TDst. The compaction process is repeated unless TD>TDst, and terminated when TD >TDst. The time to terminate the compaction process can be judged from objective standards regardless of the level of a designer's skill, so as to keep the layout design of an integrated circuit device above a certain level.Type: GrantFiled: May 5, 1998Date of Patent: March 2, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Atsuo Kondo, Takao Kuroda

Patent number: 6701500Abstract: A logic circuit module is used for designing a semiconductor integrated circuit using an FPGA (Field Programmable Gate Array) or a short-term gate array. Provided that a seventh input terminal of the logic circuit module is fixed to the power supply, a third multiplexer always selects the output of a second multiplexer, and a signal selected by the second multiplexer is directly output to a second output terminal. Moreover, an AND circuit always outputs an output signal of a first multiplexer to a first output terminal. Thus, fixing the seventh input terminal to the power supply causes respective logics formed from the first multiplexer and the second multiplexer to be separated by the third multiplexer, allowing for independent representation of the logics. Accordingly, the area efficiency of the logic circuit module is improved, resulting in reduction in size of the semiconductor integrated circuit.Type: GrantFiled: May 16, 2001Date of Patent: March 2, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventor: Noritaka Okuno

Patent number: 6700524Abstract: An A/D converter comprises a pipeline stage array in which plural pipeline stages are connected in series, each pipeline stage performing a pipeline operation on an inputted analog voltage to output a digital voltage; a number-of-bits control circuit for outputting a number-of-bits selection signal which indicates whether the operation of each pipeline stage should be carried out or halted, according to a number-of-bits control signal which indicates a resolution; and a correction circuit for compensating a digital value to be output, according to the number-of-bits control signal. Therefore, when resolution of the A/D converter, which is requested by the system, is changed, only the pipeline stages required for realizing the requested resolution are operated while the other pipeline stages are halted, whereby a reduction in power consumption of the A/D converter is realized and, simultaneously, a breakdown of an output from the A/D converter is avoided.Type: GrantFiled: September 27, 2002Date of Patent: March 2, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Junichi Naka, Yoichi Okamoto, Yoshitsugu Inagaki, Kenji Murata, Koji Oka

Patent number: 6700505Abstract: Based on searched route information and map data, a target intersection for guidance is specified. For the specified target intersection, lane data regarding the number of lanes and lane control of roads being connected thereto is read, and then recommended lane information which indicates which lane to take when entering the target intersection and to exit therefrom is generated. Based on information about the target intersection and the lane data, a simplified intersection image of the target intersection for lane guidance is generated. Based on the recommended lane information, a running path which passes through the recommended lanes for entering into and exiting from the target intersection is generated, and is combined with the intersection image. Then, lane guidance information for displaying the resultant intersection image is outputted with a predetermined timing. As such, guidance can be visually made on a screen indicating which lanes to take to enter into and exit from the intersection.Type: GrantFiled: January 4, 2002Date of Patent: March 2, 2004Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Atsushi Yamashita, Kiyomi Sakamoto, Hiroyuki Hamada, Teruaki Ata
