Patent number: 8793631Abstract: In a computing device, a computerized method and a non-transitory storage medium are applied in checking whether the transmission lines in a stored wiring diagram meet a certain criterion in relation to vias in the routes of differential pairs. A transmission line is selected to determine whether or not the line belongs to a differential pair and passes through at least one via. Another transmission line of the differential pair is obtained for analysis when the selected transmission line passes through at least one via. Sizes of vias in the respective routes of the differential pair are compared and a distance between the vias of the differential pair is compared. The differential pair, and the sizes of vias which comply or do not comply with the criterion are recorded and displayed in a list of results.Type: GrantFiled: June 27, 2013Date of Patent: July 29, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Dan-Chen Wu, Chun-Jen Chen, Ying Tso

Patent number: 8627265Abstract: In a computing device, a computerized method and a non-transitory storage medium are applied in checking a stored wiring diagram for high-noise components in close proximity to signal lines. An electronic component is selected in a PCB wiring file. A checking range of the selected electronic component is determined for searching for one or more signal transmission lines which pass within the checking range in the PCB wiring file. Basic information of the one or more signal transmission lines is recorded into a result list which is displayed on a display unit of the computing device.Type: GrantFiled: June 27, 2012Date of Patent: January 7, 2014Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Ying-Tso Lai, Dan-Chen Wu

Patent number: 8434050Abstract: A computing system includes a drawing unit and a layout unit. The computing system sets components parameters to components of a circuit diagram of a printed circuit board (PCB). The drawing unit draws the circuit diagram by using the components with the components parameters. If the drawing unit wants to use a component more than once, the computing system copies the component and the corresponding components parameters. The drawing unit uses the copied components and the corresponding parameters. If the circuit diagram has been drawn, the layout unit loads the circuit diagram and wires the PCB according to the components and the components parameters in the circuit diagram.Type: GrantFiled: August 22, 2011Date of Patent: April 30, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Shin-Ting Yen, Shou-Kuo Hsu, Yung-Chieh Chen, Dan-Chen Wu

Patent number: 8413097Abstract: A computing device reads a printed circuit board (PCB) layout file from a storage device. The PCB layout file includes arrangement information of signal lines, power lines, and power through-holes arranged on a PCB. Furthermore, the computing device sets a reference distance between a selected power through-hole and a neighboring signal line, and searches for one or more line segments of one or more signal lines where the a distance between each of the one or more line segment and the selected power through-hole is less than the reference distance.Type: GrantFiled: June 14, 2012Date of Patent: April 2, 2013Assignee: Hon Hai Precision Industry Co., Ltd.Inventors: Dan-Chen Wu, Shou-Kuo Hsu, Chun-Jen Chen
