摘要： A system and method for checking a ground via of control chips of a printed circuit board (PCB) provides a graphical user interface (GUI) displaying a layout of the PCB. The control chip has a plurality of ground pins. The computer searches for signal path routing of each ground pin and ground vias along each signal path routing of each ground pin. If there are any ground vias having the same absolute coordinates, the computer determines that the ground vias are shared by more than one ground pin.

摘要： A system and method for inspecting layout of a printed circuit board (PCB) provides a graphical user interface (GUI). The GUI displays a layout of the PCB. High side pins of a pulse width modulation (PWM) controller and a component connected to a high side pin are found. If the component is a metallic oxide semiconductor field effect transistor (MOSFET), the system calculate absolute a linear distance and a trace distance between a source pin of the MOSFET and a capacitor pin of a coupling capacitor connected to the source pin. If the linear distance, the trace distance and a capacitance of the coupling capacitor accord with a layout standard, the layout of the PCB is determined to be up to standard.

摘要： 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.

摘要： In a method for inspecting the layout of a printed circuit board (PCB), a component to be checked is determined from an electronic layout diagram of the PCB, and a power transmission line which may be serving that component is selected. The layout diagram is checked to determine whether the component is connected to the power transmission line, and further checked to determine whether more than one ground pins of the component is connected to the power transmission line. Vias that are shared by two or more ground pins of the component are determined if more than one ground pin is connected to the power transmission line. Shared vias are marked on the layout diagram.

摘要： A printed circuit board includes a first signal layer, a first reference layer, a second reference layer, and a second signal layer. An integrated circuit mounted on the first signal layer includes a power supply terminal connected to a first power supply via. The second signal layer includes a filter and a power supply wire. The filter includes a power terminal connected to the first power supply via, and a ground terminal connected to the second reference layer. The first power supply via is connected to the first reference layer through the power supply wire and a second power supply via. A void defined in the second reference layer is at least partially vertically overlapping with the power supply wire, and enables the first reference layer to function as a reference plane for the power supply wire, to increase impedance of the power supply wire.

摘要： An exemplary PCB includes a first reference layer, a first signal layer, and a second signal layer in that order. A first differential pair is arranged in the first signal layer in an edge-coupled structure referencing the first reference layer. A second differential pair is arranged in the second signal layer in edge-coupled structure. A first ground part and a second ground part are symmetrically arranged at opposite sides of the second differential pair in the second signal layer. The first differential pair is arranged above the first ground part and a projection of the first differential pair onto the second signal layer having an area coincident with the first ground part. The second differential pair references the first and second ground parts.
