By taking the generation of comb teeth (Comb) pattern simplest in IC design as an example.On a user interface along level
Direction generates the rectangle of several arbitrary shapes, draw in the vertical direction one it is perpendicular with the rectangle in above-mentioned horizontal direction
Rectangle.With simplest situation, i.e., several rectangles to extend in horizontal direction are left and right alignment, and do not need to adjust
Its position and shape, it is only necessary to change the location and shape of extension rectangle on vertical direction.As Fig. 1 gives use
Method disclosed in CN102930088B (hereinafter referred to as " method 1 ") and use method (hereinafter referred to as " method provided by the present invention
2 ") comparison of Comb figure is generated.
It includes: that (1) is designed comb teeth pattern on graphical interface of user and related to that application method 1, which generates the step of parameterized units,
And geometric figure, including the bottom square extended in 1, horizontal direction of top rectangle for extending in a horizontal direction
The side rectangle 3 extended on 2, vertical directions of shape and the inner rectangular extended in several horizontal directions for being used to form comb teeth
(comb) 4, the width one of the width and top rectangle 1 and bottom rectangle 2 that extend in 4 horizontal direction of inner rectangular (comb)
It causes, finally formed parameterized units, each comb4 needs to be equally distributed on side rectangle 3, top rectangle 1 and bottom square
Between shape 2, the left end of top rectangle 1, bottom rectangle 2 and comb4 and the right alignment of side rectangle 3, side rectangle 3
The lower end of the hanging of upper end and top rectangle 1, side rectangle 3 is aligned with the lower end of bottom rectangle 2；(2) it defines most
It needs throughout one's life at parameterized units in the visible parameter of generator listuser, the width including extension rectangle in each horizontal direction

(comb) equivalent width of the width extended in 4, comb4 horizontal direction and top rectangle 1 and bottom rectangle 2, most end form
At parameterized units, each comb4 needs to be equally distributed between side rectangle 3, top rectangle 1 and bottom rectangle 4, most
The right alignment of the left end of top rectangle 1, bottom rectangle 4 and comb3 and side rectangle, the upper end of side rectangle 3 with most push up
The lower end of the hanging of end moment shape 1, side rectangle 3 is aligned with the lower end of bottom rectangle 2；(2) definition ultimately generates parameter
Change unit to need in the visible parameter of generator listuser, the width (c_ including extension rectangle in each horizontal direction
Width) with height (c_height), the quantity (CombNum) of Comb, the distance between each Comb (M2_space), Comb
Spacing (M2_TopSpace), the spacing (M2_TopSpace) of Comb and bottom rectangle with top rectangle；(3) definition ginseng
The figure of required movement or/and deformation that numberization unit is related to；(4) the constraint relationship between imparametrization figure is defined,
It withs while with the upper left angle alignment of top rectangle, side rectangle bottom to bottom the top including side rectangle
The lower-left angle alignment of rectangle；(5) parameterized units needed for generating；The wherein the constraint relationship reference in step (4) and step (5)
Dotted line indicates in figure.
Due to the parameterized units that method 1 and method 2 ultimately generate be it is identical, one in integrated circuit design is complete
Whole unit needs corresponding parameter for editing, therefore is required to definition the first step in two methods and ultimately generates ginseng
Numberization unit is needed in the visible parameter of generator listuser.
It can be seen that in the present embodiment, the height that application method 1 changes a figure needs a more complicated height
Degree changes formula to realize, when urgent need will change height change width in need or the increase of comb quantity or generate greatly simultaneously
When measuring parameterized units, parameter in need of consideration is more and more, then the calculation formula of parametrized drawing will become extremely
It is complicated and lead to that error rate is higher and higher, parameterized units formation efficiency greatly reduces.And the position constraint in application method 2
It not only can change graph position with shape constraining but also can change graphics shape, it operationally can be with visual pattern and simple
Victory is quickly generated parameterized units, is also required to when design complexities increase in view of the influence to other shapes, but its
Design efficiency has great raising, and error rate is significantly reduced.
