Embodiment
For the ease of describing the present invention, introduce earlier the notion that signal disturbs for example.
With Fig. 1 and Fig. 2 is example, and PH1 and PH2 are phase place (phase) node voltage of changeover voltage adjuster.The voltage of phase node has high voltage amplitude (dv/dt), and voltage amplitude falls within the three ten-day period of hot season (as 2 volts) between 12 volts.P12VA is one 12 volts of power supplys and is positioned at PH1 and the adjacent layer of PH2, and there is the overlapping region in PH1 node and P12VA, and PH2 node and P12VA do not have the overlapping region.Because can form a capacity effect between two adjacent parallel metal sheets, when the voltage of PH1 node switched in moment, noise can be through PH1 node and the formed P12VA that is capacitively coupled in P12VA overlapping region.Because PH2 node and P12VA do not have the overlapping region, so when the voltage of PH2 node switched in moment, have only very little noise to be coupled to P12VA.
With Fig. 3 is example.It is reference planes with P12VA that a signal wire BMC_FAN6_TACH is arranged.Result by Fig. 1 and Fig. 2 can know that P12VA has the voltage noise of high voltage amplitude, so on corresponding time point, can produce noise on the signal wire.Wherein, this signal wire BMC_FAN6_TACH is used for the control system rotation speed of the fan with P12VA, if excessive noise is arranged, can make that then the rotating speed of system fan is fluctuated.
As shown in Figure 4, be the structural representation of test computer of the present invention.In the present embodiment, said test computer 2 comprises display device 20, input equipment 22, storer 23, automatic wiring check system 24 and the processor 25 that links to each other through data bus.Be appreciated that in other embodiments said automatic wiring check system 24 also can be arranged at other calculation element, in server.
Said automatic wiring check system 24 is used for searching automatically the overlapping signal wire of selecting with the user of power lead, describes below the detailed process.
Said storer 23 is used to store data such as program code and PCB (Printed Circuit Board, printed circuit board (PCB)) the wiring diagram shelves of said automatic wiring check system 24.Said display device 20 and input equipment 22 are used as the input-output device of test computer 2.
In the present embodiment; Said automatic wiring check system 24 can be divided into one or more modules; Said one or more module is stored in the said storer 23 and is configured to and carried out by one or more processors (present embodiment is a processor 25), to accomplish the present invention.For example, consult shown in Figure 5ly, said automatic wiring check system 24 is divided into power lead and selects module 201, signal wire to search module 202, signal wire mark module 203 and output module 204 as a result.The alleged module of the present invention is to accomplish the program segment of a specific function, is more suitable in describing the implementation of software in test computer 2 than program, will in the process flow diagram of Fig. 6, specifically describe about the function of each module.

Step S1, power lead select module 201 to receive the power lead that the user selects in PCB layout figure shelves.In other embodiments, the user also can once select many power leads.
Step S2, signal wire search module 202 and in this PCB layout figure shelves, search the signal wire overlapping with the power lead of this selection.
In the present embodiment; Signal wire is searched the minimum area-encasing rectangle that module 202 is calculated the power lead of this selection; Calculate the common factor of every signal line in this minimum area-encasing rectangle and the PCB layout figure shelves then; If there is common factor to represent that then the power lead of this selection and this signal wire have overlapping (consulting shown in Figure 7), do not represent that then the power lead of this selection and this signal wire do not have overlapping (consulting shown in Figure 8) if having to occur simultaneously.Consult shown in Figure 7ly, power lead 50 has overlapping with signal wire 52.Consult shown in Figure 8ly, power lead 50 does not have overlapping with this signal wire 52.In the present embodiment, signal wire is searched module 202 and can be utilized parallel algorithm (Parallel Algorithm) to calculate the minimum area-encasing rectangle of the power lead of this selection.
In other embodiments; The module 202 of searching signal wire also can adopt the power lead that will select to be regarded as polygon and signal wire is got common factor; If there have common factor to represent that then power lead and this signal wire of this selection have to be overlapping, and overlapping signal wire title is shown to the results list.
Consult shown in Figure 9ly, the power lead key word 60 that the user can input need be searched on software interface 6, power lead select module 201 will obtain all power lead titles 61 that retrieve that comprise this power lead key word 60.The user can continue need to select the power lead 62 of inspection, clicks double line review button 63 then.Signal wire is searched module 202 will search all signal wires 64 (be designated as the overlapped signal line 64 that retrieve) overlapping with the power lead of the needs of this selection inspection 62, and then, the user need can select the overlapped signal line 65 of inspection.
Step S3, the attribute information of the attribute information of the signal wire that finds among the signal wire mark module 203 markers step S2 and the power lead of this selection.In the present embodiment, the attribute information of said signal wire comprises position, coordinate and the level on printed circuit board (PCB) of signal wire.The attribute information of said power lead comprises position, coordinate and the level on printed circuit board (PCB) of the power lead of this selection.
Consult shown in Figure 9ly, show the level 67 of the power lead of this selection on the software interface 6, and the level 68 of overlapped signal line.When the user clicks marking signal line position button 66, signal wire mark module 203 will be in PCB layout figure shelves 7 position (consulting shown in Figure 10) of this overlapped signal line of mark.
Step S4, when the user selected to derive the wiring check result, output module 204 was exported the attribute information of the power lead of these signal wires that find and this selection as a result.
What should explain at last is; Above embodiment is only unrestricted in order to technical scheme of the present invention to be described; Although the present invention is specified with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement technical scheme of the present invention, and do not break away from the spirit and the scope of technical scheme of the present invention.
