Consulting shown in Figure 1ly, is the applied environment figure of wiring inspection system 10 preferred embodiments of the present invention.This wiring inspection system 10 is applied to calculation element 100.This calculation element 100 also comprises processor 20, storer 30, display 40 and printed circuit board (PCB) (printed circuit board, PCB) wiring diagram file 50.Distance between that this wiring inspection system 10 is used for checking PCB layout the map file 50 and power supply perforation does not satisfy the electric wire of cabling requirement, to prevent the power lead that passes the power supply perforation near electric wire is caused coupled interference.PCB generally is comprised of multilayer circuit board, for example signals layer, bus plane, ground plane.Perforation refers to the hole of the upper different aspects of conducting PCB, and the power supply perforation refers to the hole that power lead passes.Described electric wire comprises various types of wirings such as all power leads except the power lead that passes this power supply perforation, signal wire, ground wire.Power lead means the electric wire of the upper transmission current of PCB, and signal wire means the electric wire of the upper signal transmission of PCB.
Consulting shown in Figure 2ly, is the functional block diagram of wiring inspection system 10 preferred embodiments of the present invention.This wiring inspection system 10 comprises read module 11, module 12 is set, selects module 13, checking module 14, display module 15 and locating module 16.Function below in conjunction with Fig. 3 specification module 11～16.
Consulting shown in Figure 3ly, is the process flow diagram of wire inspection method preferred embodiment of the present invention.According to different demands, the order of step can change in this process flow diagram, and some step can be omitted, for example step S309 and S311.
Step S301, read module 11 read PCB layout map file 50 from storer 30.
Step S303 arranges module 12 and receive electric wire and the gauged distance d of power supply perforation, for example d=40mil in the PCB layout map file 50 that users input on the user interface that this wiring inspection system 10 provides.1mil equals mil.As mentioned above, described electric wire comprises various types of wirings such as all power leads except the power lead that passes this power supply perforation, signal wire, ground wire.Power lead means the electric wire of the upper transmission current of PCB, and signal wire means the electric wire of the upper signal transmission of PCB.
Step S305, display module 15 show the title of all power leads in the PCB layout map file 50 in the first viewing area that this user interface provides, select module 13 to receive a power lead of user selection.The user also can once select many power leads.
Step S307, checking module 14 find out all power supply perforations of this power lead process from PCB layout map file 50, and find out and the distance of each the power supply perforation electric wire line segment less than described gauged distance.For example, shown in Fig. 4 (I), annulus A1 represents a power supply perforation, take this power supply perforation central point as the center of circle, gauged distance (for example d=40mil) generates a circle (representing with dummy line among Fig. 4 (I)) for radius, and then all fall into the distance of the interior signal line segment of this circle and this power supply perforation all less than described gauged distance in the PCB layout map file 50.Here the circle that generates is not limited to the circuit board aspect at this power supply perforation place, also can be the plane vertical with the circuit board aspect at this power supply perforation place, so that from the electric wire that passes the various boards aspect, find out with the distance of this power supply perforation all less than the electric wire of described gauged distance.An electric wire on the PCB, for example signal wire may be comprised of a plurality of line segments, and the different line segments on the same electric wire are different from the distance possibility of same power supplies perforation.
Step S309, display module 15 shows the coordinate of each perforation that finds and the title of electric wire line segment at the second area that this user interface provides.
Step S311, select module 13 to receive the power supply perforation (or an electric wire line segment) that the user selects from this second area, locating module 16 jump in the PCB layout map file 50 this selection of location power supply perforation (or electric wire line segment) and with the distance of this perforation (or electric wire line segment) the electric wire line segment (or power supply perforation) less than described gauged distance, revise the wires design of this electric wire line segment with prompting user.For example, suppose that the user selects a bars line segment L1 from this second area, shown in Fig. 4 (II), locating module 16 jump in the wiring diagram file 50 with highlighted mode locate this signal line segment L1 and with the distance of this signal line segment L1 power supply perforation A5 less than described gauged distance.
Step S313, checking module 14 check whether also have power lead to be selected in the PCB layout map file 50.If also have other power lead not selected, then return step S305, if all power leads all were selected, then flow process finishes.
It should be noted that at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although with reference to preferred embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement technical scheme of the present invention, and not break away from the spirit and scope of technical solution of the present invention.
