Below in conjunction with accompanying drawing describe in detail involved in the present invention to the resistance calculations method treating wiring area dividing method, geometry subsegment and the computing method of netting twine width adjustment value.
Treat wiring area dividing method:
Fig. 3 is the segmentation schematic diagram that the present invention treats wiring area.As shown in Figure 3, the region that in figure, solid line surrounds is treats wiring area.As can be known from Fig. 3, will treat that wiring area is divided into the irregular convex quadrangle of three tandems after over-segmentation.
Fig. 4 is the another kind segmentation schematic diagram that the present invention treats wiring area.As shown in Figure 4, treat after wiring area splits through over-segmentation interconnect module 20, will treat that wiring area has been divided into the series connection of a triangle and two convex quadrangles.
In figs. 3 and 4, four blockages on L0R0 and L3R3 limit represent netting twine port PIN, and the PIN number playing initial line L0R0 and terminal edge L3R3 is determined according to actual conditions.
Through the segmentation of over-segmentation interconnect module 20, treat that the every root netting twine in wiring area is also divided into several geometry subsegments, computation analysis module 30 calculates the resistance value of each geometry subsegment of every root netting twine, carries out the cumulative resistance value obtaining corresponding netting twine to the resistance value of the geometry subsegment of every root netting twine.Concrete, before the carrying out for the treatment of wiring area at segmentation interconnect module 20 is split, every root netting twine that computation analysis module 30 treats wiring area is numbered, as N1, N2, N3 ... Nn.After every root netting twine is divided into several little geometry subsegments, each geometry subsegment of computation analysis module 20 to every root netting twine is numbered accordingly.Each geometry subsegment as N1 is labeled as N10, N11, N12 ... each geometry subsegment of N1m, N1 is labeled as N20, N21, N22 ... N2m, wherein n >=1, m >=1.After calculating the resistance value of each geometry subsegment, according to the cumulative resistance value that just can obtain corresponding netting twine of its numbering.
Concrete, segmentation interconnect module 20 is treated wiring area by following three kinds of methods and is split.
Method one: make corresponding inner edge according to the situation that angular bisector is crossing in outside, other angular bisectors, an initial line and terminal edge at first, will treat that wiring area is divided into convex quadrangle and/or triangle thus.As L1R1 and L2R2 in Fig. 3 and Fig. 4 is respectively the angular bisector of ∠ L0L1L2 and ∠ L1L2L3.
Concrete, find out and do not playing a summit on initial line L0R0 and/or terminal edge L3R3, and treat in wiring area, to make its angular bisector with the angle that summit is formed;
As shown in Figure 3, if angular bisector is crossing with certain outside on opposite at first, can be used as an inner edge between this summit and this joining, as L2R2 and L1R1 in Fig. 3.Then will treat that wiring area L0R0R1R2R3L3L2L1 divide into three geometry subsegments, be respectively convex quadrangle L2L3R3R2, convex quadrangle L1L2R2R1 and convex quadrangle L0L1R1R0.
As shown in Figure 4, if angular bisector is first crossing with another angular bisector, connect summit corresponding to two angular bisectors intersected as inner edge, as L1R1 and L2R2. in Fig. 4 will treat that wiring area is divided into convex quadrangle L2L3R3R1, triangle L1L2R1 and convex quadrangle L0L1R1R0.
If angular bisector is crossing with of rising in initial line and/or terminal edge, connect this summit with any one summit of rising on initial line and/or terminal edge as inner edge.Such as, if L2R2 and L0R0 in Fig. 3 intersects, then connect Vertex L2 and summit R0, forms inner edge L2R0 respectively.When R0R3 is straight line, will treat that wiring area has been divided into triangle L0L1R0 and convex quadrangle R0L2L3R3.
If the quadrilateral section marked off is not convex quadrangle or triangle, again segmentation is carried out to this quadrilateral section and make it meet convex quadrangle or triangle.

Method three: make to have removed initial line and be connected with nearest summit with all the other summits on the summit on terminal edge.Concrete, removing rising outside the summit on initial line and terminal edge, summit nearest with its opposite for other all summits being connected, then will treating that wiring area is divided into triangle or quadrilateral.Further, user can according to treating that the number of the size of wiring area, both port of origination and termination port manually selects the division hop count to wiring area.So that computation analysis module calculates resistance value and reduces computational complexity, improve wiring efficiency.
The resistance calculations method of geometry subsegment:
If this geometry subsegment is isosceles trapezoid, then the method calculating this geometry subsegment resistance is as follows:
If the width that isosceles trapezoid is gone to the bottom is respectively w
0and w
1, height is L.Isosceles trapezoid can regard what numerous little isosceles trapezoid was concatenated as, and each little trapezoidal length is.Then the little trapezoidal width of distance base x is
Its resistance is
Whole trapezoidal resistance is
When this geometry subsegment is any convex quadrangle, then the method calculating this geometry subsegment resistance is as follows:
Geometry subsegment after any netting twine is divided can regard a quadrilateral as, therefore needs to find the upper and lower bottom width degree of the equivalence of quadrilateral and equivalent height.
Fig. 5 is the schematic diagram calculating any convex quadrangle resistance.As shown in Figure 5, the resistance value of estimation L1R1 to L2R2, find out and connect the equivalent height of mid point as convex quadrangle of two opposite side L1R1 and L2R2 of convex quadrangle, C1, C2 are respectively the mid point of L1R1 and L2R2, the equivalent height of quadrilateral is C1C2, and the upper and lower bottom width degree of equivalence of estimation quadrilateral has two kinds of methods.
Method one: obtain the equivalent upper base width of quadrilateral and equivalence according to the line of two mid points and the angle of two opposite side and to go to the bottom width.Concrete, if the angle of C1C2 and L1R1 is α, L1R1, corresponding base width can be estimated as | L1R1|sin α; The corresponding base of L2R2 is that width also can be tried to achieve by similar approach.
Method two: obtain equivalent upper base width and equivalence according to four summits of convex quadrangle to the distance of the line of two mid points and to go to the bottom width.Concrete, if the distance of L1 and L2 to C1C2 is d1 and d2 respectively, the distance of obvious R1 and R2 to C1C2 is also d1 and d2 respectively.Then two of quadrilateral equivalent bottom width degree are exactly 2*d1 and 2*d2.
The resistance integral formula applying mechanically isosceles trapezoid according to equivalence upper and lower bottom width degree and equivalent height just can obtain the resistance value of any convex quadrangle.
In like manner, when geometry subsegment is triangle, can refer to the resistance calculations method calculating convex quadrangle and obtain leg-of-mutton resistance value, as asked equivalent height and equivalent bottom width, being not repeated herein.
The computing method of netting twine width adjustment value:
Suppose there is n bar netting twine, after over-segmentation interconnect module 20, n bar netting twine is divided into altogether m section, is seen the answer L about segmentation of problem 10 between jth section and jth+1 section by the definition of inner edge inner edge

Concrete, the step calculating netting twine width adjustment value is as follows:
S1: calculate every resistance value of root netting twine and the difference of average resistance and be stored as resistance difference.Concrete, calculate the resistance value from both port of origination to every root netting twine of termination port, resistance value based on every root netting twine obtains treating that the average resistance of all netting twines in wiring area is target resistance values, records every resistance of root netting twine and the difference of target resistance values is stored as resistance difference Δ r
i.
S2: calculate the weight treating every bar inner edge in wiring area.Concrete, if wiring area is divided into m section, the length of the mid point line of two inner edges of jth section is designated as S
j, and the relative weighting of every bar inner edge is designated as
S3: the resistance calculating each geometry subsegment, and it is differentiated.Calculate the differential of each geometry subsegment of every root netting twine.
Fig. 6 is the schematic diagram of computational geometry subsegment differential.As shown in Figure 6, suppose that the angle of port mid point line and L1R1 and L2R2 is respectively α and β, the equivalent width at quadrilateral two end is estimated as | L1R1|sin α and | L2R2|sin β, apply mechanically the resistance calculations formula of isosceles trapezoid, can obtain its resistance is
resistance r is asked | the derivative of L1R1|, obtains
When the inner edge of R1 along L1R1 place among a small circle moves Δ | after L1R1| to R1 ', L2R2 is constant; The equivalent length of quadrilateral mid point wire length C1C2 and quadrilateral, the change of angle α and β are second order a small amount of, also can think that they are constant.Then resistance now just change can be approximately
it is linear that this pass ties up in less scope.
