Abstract
A kind of method that the invention discloses automatic inspection high-speed line live width, belong to PCB design technical field, the present invention solves the most quickly to check the problem whether high-speed line live width meets constraints, the technical scheme used is: being the high-speed line live width method that whether meets constraints that automatically checks, step is as follows: (1), every pair of high-speed-differential line in the constraints of PCB is carried out live width attribute typing；(2) comparison and detection of live width, is carried out one by one according to the order of high-speed-differential line in constraints；When the design of PCB, enable command, by logic XOR, i.e. detect when the line width information of PCB high speed differential lines is consistent with the line width information of typing before, be 1；Detect when the line width information of PCB high speed differential lines is inconsistent with the line width information of typing before, be 0；After the high-speed-differential line name that ejection correct in human window is ineligible, continuing executing with order, until having detected all of high-speed-differential line, order terminates.
Description
Technical field
The present invention relates to a kind of PCB design technical field, a kind of method of automatic inspection high-speed line live width.
Background technology
Along with the development of electronic information technology, the integrated level of electronic product is more and more higher, and high-speed line is as each
The transmission tie of function, its status taken in the design of PCB is also come the highest.How it can the most high-quality be set
Meter also becomes the problem that Layout engineer becomes more concerned with.
Whether high-speed line live width meets at present constraints (Constraints) is all that manual calculations is also wasted and much set
Between timing.
Summary of the invention
The technical assignment of the present invention is for above not enough, it is provided that a kind of method of automatic inspection high-speed line live width, solves
Certainly the most quickly check the problem whether high-speed line live width meets constraints.
The technical assignment of the present invention realizes in the following manner,
A kind of method of automatic inspection high-speed line live width, is the method whether high-speed line live width meets constraints that automatically checks,
Step is as follows:
(1), the inner every pair of high-speed-differential line of the constraints (Constraints) (Differential Pair) of PCB is carried out line
Wide attribute typing；
(2) comparison and detection of live width, is carried out one by one according to the order of high-speed-differential line in constraints.
The concrete operations of step (2) are:
1., the live width of every pair of high-speed-differential line is progressively detected, progressively detect the line width information of every pair of high-speed-differential line with
The line width information of typing before is the most consistent；
2., when detected value is 1, this line width information to high-speed-differential line and the line width information one of typing before in PCB are described
Cause, continue executing with order, on；
3., when detected value is 0, illustrate in PCB that this is to the line width information of the line width information of high-speed-differential line and typing before not
Unanimously, this orders time-out, for done；
4., certain is when being 0 to high-speed-differential line detected value, ejects corresponding human window, and high-speed-differential line name is shown by this
Human window；
5., after the high-speed-differential line name that ejection correct in human window is ineligible, this order is continued executing with.
Step (2) 3. in, this order suspend 0.5 second.Purpose is in fortune by ineligible high-speed-differential line name
Row window ejects.
When the design of PCB, enable command, by logic XOR, the live width of PCB high speed differential lines i.e. detected
When information is consistent with the line width information of typing before, it is 1；Line width information and the typing before of PCB high speed differential lines detected
Line width information inconsistent time, be 0；After the high-speed-differential line name that ejection correct in human window is ineligible, continue
Performing order, until having detected all of high-speed-differential line, order terminates.
The method of a kind of automatic inspection high-speed line live width of the present invention has the advantage that and can quickly check high-speed line
Whether live width meets constraints, the quick design of beneficially PCB, effectively prevent manual examination (check) every pair differential lines in the design
The operation of live width and the workload of redundancy brought, be greatly improved desin speed and the quality of PCB.
Accompanying drawing explanation
The present invention is further described below in conjunction with the accompanying drawings.
Accompanying drawing 1 is the flow chart of a kind of method of automatic inspection high-speed line live width.
