Abstract

A method for automatically checking signal areas includes: recording etching line information of etching lines which divide an internal plane of an opened PCB file into a plurality of signal areas, recording input signal names and positions where the input signal names are arranged, obtaining the outline information of the opened internal plane and the etching line information, obtaining position information of points within each signal areas according to the outline information and the etching line information, determining whether one signal area is associated with one input signal name, determining whether the one input signal name matches one standard signal name, and setting one input signal name as a name attribute of the signal area associated with the one input signal name if the one input signal name matches one standard signal name. A related PCB system is also provided.

Dependent claims

A printed circuit board (PCB) layout system, comprising:

a storage unit storing a plurality of PCB layout files and a standard signal name file listing all standard signal names of the PCB layout system, each of the PCB layout files comprising outline information defining an outline of an internal plane of each of the PCB layout files;
and
a processing unit comprising a plurality of executions to:
display an outline of an internal plane of an opened PCB layout file;
record etching line information of etching lines, wherein the etching lines divide the internal plane into a plurality of signal areas;
record input signal names and positions where the input signal names are arranged;
obtain the outline information of the internal plane and the etching line information in response to user input;
perform a logical operation according to the obtained outline information and the obtained etching line information to obtain the position information of points within each of the signal areas;
perform an intersection operation to determine whether one of the signal areas is associated with one of the input signal names;
compare one of the input signal names associated with one of the signal areas with the standard signal names to determine whether the one of the input signal names matches one of the standard signal names;
and
set one of the input signal names as a name attribute of the signal area associated with the one of the input signal names if the one of the input signal names matches one of the standard signal names.
