ABSTRACT:
An automatic system for providing printed circuit board (PCB) layout of a PCB includes an input device, a data processing device, and a storage device. The data processing device includes an invoking module, a calculating module, and a determining module. The invoking module is to read a name and a thickness of each layer of the PCB from the storage device. The calculating module is to calculate an actual length of a via stub of each layer according to the name and thickness of each layer, and calculate an ideal length of the via stub of the PCB according to input information from the input device, and a preset formula. The determining module is to compare the ideal length and the actual length of the via stub of each layer to determine whether the layer can be used as a high-speed signal layout layer or not.
