A Method and System for Providing a Three-Way Cross Probing Between a Schematic, Layout and Real PCB Board

Disclosed is a method and system of providing a three-way cross probing between a schematic, layout and real Printed Circuit Board (PCB). The method and system involves cross probing between a schematic and a layout, cross probing between a schematic and a PCB board and cross probing between a layout and a PCB board.

In accordance with the method and system, a 3-way cross probing between a schematic, layout and real Printed Circuit Board (PCB) is illustrated in Fig. 1.

Figure 1

The system includes a component locating mechanical attached to the PCB board. The component uses a two-axis mechanical system and operates in similar to desktop-sized flat-bed pen plotters. The PCB board is placed on the flat-bed and the pens mounted on a traveling bar as illustrated in Fig. 2.

Figure 2

A y-axis is represented by motion up and down the length of the travelling bar and x-axis is represented by motion of the travelling bar back and forth across a plotting table of the PCB board. The traveling bar is installed higher and longer, to assist a hardware designer to probe signals or replace the components. The pen may be replaced with a Light Emitting Diode (LED) or a laser to point to the component located on the PCB board.

The position information is transferred or received between the electric design files and PCB board from four directions. One of the directions is from a schematic window to the PCB board. The schematic window is highlighted using a component. The position information of the components in a x, y, and z axis may be retrieved from component placement file generated by a layout tool. Information is then transferred from host software to a component locating mechanical system. The traveling bar with a pointer pen moves to the right position on the PCB board. So the component highlight on the schematic window may be located on the PCB board.

Another direction is from layout window to PCB board. In this case, a component is highlighted on the layout window. The position information of the components in the x, y, and z axis is transferred from the host software to the component loca...
