The present invention is a kind of comparative approach with its modification situation of the automatic contrast circuit design drawing of software, see also shown in Figure 1, this method is when utilizing computing machine to draw a circuit design drawing, make its last version 1 of this circuit design drawing be drawn by first chromatograph (as: yellow), and when the element on its last version 1 of circuit design drawing (as resistance R 1 and capacitor C 501) is made amendment or changed, this circuit design drawing then change by second chromatograph (as: purple) draw become the back one version 2, therefore, when the difference condition between desire resolution its last version of circuit design drawing and back one version 2, can with computing machine on utilize an automatic contrast program, on last version 1, make comparisons a back version 2 of circuit design drawing is superimposed, and the difference condition after will comparing displays on display screen, so, utilize the difference of color, can be on computer screen, manifest and distinguish out difference condition between two versions.
So can learn, its last version 1 of this circuit design drawing and back one version 2 are between the two, if when not doing any change or modification at all, then its last version 1 of this circuit design drawing will fully be covered by back one version 2, thereby on display screen, only can see the circuit design drawing of a back version 2 of being drawn by second chromatograph (as: purple).
In like manner as can be known, because oneself does to change or revise between its last version 1 of this circuit design drawing and back one version 2, to cause this circuit design drawing thereafter a version 2 can't be covered in fully on the last version 1, therefore, on display screen, circuit design drawing after contrast, second chromatograph (as: purple) that a main still later version 2 is adopted manifests, but the element or the design of change or modification to some extent, then respectively by first chromatograph (as: yellow) that is adopted of last version 1, and back second chromatograph (as: purple) that adopted of one version 2 manifests, and uses and distinguishes out the difference condition of this circuit design drawing before and after correcting.
The front of a circuit board and reverse side all may be provided with electronic component, and for example: the front is provided with a resistance R 1, and reverse side is provided with a capacitor C 501.When automatic contrast program makes the back version 2 of circuit design drawing superimposed on last version 1 time, with regard to positive, if any change is not done in the position that is provided with of resistance R 1 between the version of front and back, then only can see the color of the resistance of back one version, as grey, because of back one version is covered on the last version fully; Otherwise, if change the position of resistance R 1, then can not only see the grey of the resistance of back one version, can also see not the color of the last version that is covered by grey, as green; So, can find out the change conditions of resistance between the version of front and back.
Figure 1 shows that one embodiment of the invention, the last version 1 of this circuit design drawing comprises a picture frame 11, a front Figure 12 and a reverse side Figure 13, wherein the picture frame 11 of this last version 1 is drawn by first color (as: redness), all elements on its front Figure 12 (top) or design are drawn by second color (as: green), and all elements on its reverse side Figure 13 (button) or design are then drawn by the 3rd color (as: blueness); Last version 1 then becomes back one version 2 after revising, be to comprise a picture frame 21, one front Figure 22 and a reverse side Figure 23, the picture frame 21 of this back one version 2 is drawn by the 4th color (as: orange), all elements on the Figure 22 of its front or design are drawn by the 5th color (as: grey), all elements on its reverse side Figure 23 or design are then drawn by the 6th color (as: brown), therefore, as long as layout slip-stick artist is this automatic contrast program of utilization, make this circuit design drawing that a version 2 is superimposed on last version 1 thereafter, utilize the difference of color, on computer display, demonstrate between two versions in picture frame, difference between front view (FV) and the reverse side figure, can judge the change situation between two versions, its comparative case is as follows:
(1) picture frame: the picture frame 11 of last version and the picture frame 21 of back one version 2, this between the two, if do not do any change or modification, then the picture frame 11 of last version will fully be covered by the picture frame 21 of back one version 2, in other words, on display screen, only can see the picture frame 21 of a back version 2 of being drawn by the 4th color (as: orange); Otherwise, in the picture frame 21 of the picture frame 11 of last version 1 and back one version 2 between the two, if done change or modification, then the picture frame 21 of back one version 2 can't be covered on the picture frame 11 of last version 1 fully, therefore, on display screen, the 4th color (as: orange) that the main still picture frame 21 of a later version 2 is adopted manifests, but element that has changed or revised or design, first color (as: redness) that is adopted simultaneously then by the picture frame 11 of last version 1, and the 4th color (as: orange) that adopted of picture frame 21 of back one version 2 shows, uses to distinguish out that institute before and after the correcting does to change or the difference place of modification.
(2) front view (FV): front Figure 22 of front view (FV) of last version 1 (top) 12 and back one version 2, this between the two, if do not do any change or modification, front Figure 12 of then last version 1 will fully be covered by front Figure 22 of back one version 2, in other words, on display screen, only can see front Figure 22 of a back version 2 of being drawn by the 5th color (as: grey); Otherwise, in the front of last version 1 Figure 12 with the back one version 2 front Figure 22 between the two, if made any change or modification, then front Figure 22 of back one version 2 can't be covered on front Figure 12 of last version 1 fully, therefore, on display screen, the 5th color (as: grey) that main still front Figure 22 of a later version is adopted manifests, but the element or the design of change or modification to some extent, second color (as: green) that is adopted simultaneously then by front Figure 12 of last version, and the 5th color (as: grey) that adopted of front Figure 22 of back one version shows, uses and distinguishes out change or the modification of being done before and after the correcting.
(3) reverse side figure: the reverse side figure (button) 13 of last version and reverse side Figure 23 of back one version, this between the two, if do not do any change or modification, then reverse side Figure 13 of last version will fully be covered by reverse side Figure 23 of back one version, in other words, on display screen, only can see reverse side Figure 23 of a back version of being drawn by the 6th color (as: brown); Otherwise, in reverse side Figure 23 of reverse side Figure 13 of last version and back one version between the two, if oneself does any change or modification, then reverse side Figure 23 of back one version can't cover on reverse side Figure 13 of last version fully, therefore, on display screen, the 6th color (as: brown) that main still reverse side Figure 23 of a later version is adopted manifests, but the element or the design of change or modification to some extent, the 3rd color (as: blueness) that is adopted simultaneously then by reverse side Figure 13 of last version, and the 6th color (as: brown) that adopted of reverse side Figure 23 of back one version shows, uses to distinguish out that institute before and after the correcting does to change or the different place of modification.
Modern hypothesis, circuit designer sends the layout slip-stick artist in previous circuit design drawing with the A version, but in the future, circuit designer is made amendment to the circuit design drawing of this A version, and the circuit design drawing of called after B version, and send the layout slip-stick artist once more to, when this layout slip-stick artist when receiving the circuit design drawing of B version, can utilize this automatic contrast program to compare, and the results are shown on the display screen after will contrasting, thereby watch the picture frame of this circuit design drawing as the layout slip-stick artist after, the picture frame that can find circuit design drawing is mainly manifested by orange institute, and some part is then manifested by red institute, so can learn, the picture frame of this circuit design drawing before and after correcting done a little modification or change; When the layout slip-stick artist watches its front view (FV) of this circuit design drawing (top), find a resistance R 1 set on this front view (FV), manifest with grey by green respectively, and other element or the design except resistance R 1 on this front view (FV), then still manifest, so can learn the front view (FV) of this circuit design drawing before and after correcting with grey, only this resistance R 1 position of being laid was changed, and all the other elements or design then are not corrected or change; When the layout slip-stick artist watches its reverse side of this circuit design drawing figure (button), find a capacitor C 501 set on this reverse side figure, be respectively by blue and brown manifesting, and other element or the design except capacitor C 501 on the reverse side figure, then still manifest, so can learn the reverse side figure of this circuit design drawing before and after correcting with brown, only this capacitor C 501 position of being laid was changed, and all the other elements or design then are not corrected or change.
In the present invention, this automatic contrast program is with a circuit design drawing version 2 thereafter, superimposed when on the circuit design drawing of last version 1, making comparisons, to show that on display screen one selects dialog box, be provided with a plural number option in this selection dialog box, for example: " demonstration picture frame ", " demonstration front view (FV) ", " show reverse side figure ", " manifest simultaneously " ... Deng, so, layout slip-stick artist can utilize mouse to click the picture that each sub-option comes control display screen to manifest, for example, when clicking this " demonstration picture frame ", if the picture frame 11 in last version has been done change or modification between the two with the picture frame 21 of back one version, then the picture frame 21 of this back one version can't be covered on the picture frame 11 of last version fully, so, on display screen, main the 4th color that is still adopted with the picture frame 21 of this back one version manifests, but the element or the design of change or modification to some extent, first color (as: redness) that is adopted simultaneously then by the picture frame 11 of last version, and the 4th color (as: orange) that adopted of the picture frame 21 of this back one version shows, uses that institute before and after difference or the prompting correcting does to change or the difference place of modification; In like manner as can be known, when the layout slip-stick artist clicks " manifesting simultaneously " this option, then on display screen, will be divided into three windows, use the picture frame, front view (FV) and the reverse side figure that manifest this circuit design drawing respectively, the difference condition between last version 1 and back one version 2.
See also shown in Figure 2, be another embodiment of the present invention, the last version 1 of this circuit design drawing is on display screen, can show the coordinate figure (X of set each element on it, Y), for example: the coordinate figure (X1 of resistance R 2, Y1), coordinate figure (the X2 of capacitor C 502, Y2), and a back version 2 of this circuit design drawing is on display screen, also can show the coordinate figure (X of set each element on it, Y), for example: the coordinate figure (X3 of resistance R 3, Y3), coordinate figure (the X4 of capacitor C 502, Y4), when this automatic contrast program with a back version 2 of this circuit design drawing is superimposed when making comparisons on last version 1, its last version 1 of this circuit design drawing and back one version 2 are between the two, it does not make the element of any change or modification, for example: the capacitor C 502 of last version and the capacitor C 502 of back one version, at this moment, the capacitor C 502 of this its last version of circuit design drawing will fully be covered by the capacitor C 502 of back one version, thereby on display screen, this capacitor C 502 only shows one group of coordinate figure (X, Y), that is capacitor C 502 its coordinate figures of back one version (X4, Y4).
In like manner as can be known, see also shown in Figure 2, because between its last version 1 of this circuit design drawing and back one version 2, some element has been done change or has been revised, for example: the resistance R 2 of last version moves right, and is replaced with the resistance R 3 of back one version, at this moment, because the resistance R 3 of back one version can't fully be covered on the resistance R 2 of last version, therefore, the circuit design drawing after contrast, on display screen, then show two groups of coordinate figure (X simultaneously, Y), that is resistance R 2 its coordinate figures of last version (X1, Y1), and resistance R 3 its coordinate figure (X3 of back one version, Y3), use and indicate this resistance R 2, the difference condition of R3 its coordinate figure before and after correcting.
Wherein, (X Y), is that the lower left corner with display screen is origin (0 to the coordinate of components and parts, 0), and the coordinate of components and parts (X, Y), be meant components and parts the center a bit, for example: the coordinate of last version 1 resistance is (2,5), and the coordinate of back one version 2 resistance is (4,5).
In addition, should be noted that, the contents of program of described automatic contrast program, can write by any program language, as long as it can make a back version 2 of circuit design drawing superimposed on last version 1, and utilize the difference of color or coordinate, on computer display, show that the difference condition in picture frame, front view (FV) and reverse side figure gets final product between two versions.
Because the shortcoming of prior art, the inventor is behind the permanent effort of process research and experiment, finally development and Design goes out a kind of comparative approach with its modification situation of the automatic contrast circuit design drawing of software of the present invention, mainly be with an automatic contrast program, according to the different coordinate of components and parts on new and old difference figure layer color that devises and draw the blueprint or two versions, compare, make the layout slip-stick artist can promptly find out both difference places, be beneficial to this circuit design drawing is carried out layout.Phase can contribute industrial community to some extent with by proposition of the present invention.
