Abstract

The invention discloses a method of setting spacing copy patterns by group. The method is characterized in that the spaces among a group of objects are different values according to the bundle number of each batch of self-defined objects and the pitch step of the space of each batch of objects. The method comprises the steps of sequentially carrying out batch operation to the total number of objects to be copied by a value according to the number of each batch of objects, wherein a space between the first group of objects is obtained by calculating the distance between a first object and a second object placed in a drawing area of a user, and then a space value of each batch of objects is obtained by adding the pitch step to the space of the last batch of objects. According to the method provided by the invention, a plurality of objects obtained by copying can be automatically divided into a plurality of batches, and objects can be automatically placed according to a space value in each batch of the objects.

Description

A kind of method by group setting spacing copy pattern

Technical field

The method setting spacing copy pattern by group is copied as by object multiple in EDA layout design field simultaneously and divides an object by group, and the spacing often organizing object is set to according to certain rules the method for different distances.The invention belongs to eda tool layout design field.

Background technology

EDA(electric design automation) instrument is in layout design, can a large amount of graphings (as Path, Rectangle, Polygon, Guard Ring etc.) and create device (Instance), for the object that parameter is identical usually use copy (Copy) order realize creating object faster.But the object space obtained after copying not is user wishes, or spacing between object do not meet the requirement of user.Such as in the domain of flat-panel monitor design, in order to offset thermal expansion, deviser needs the Pad unit be connected with IC device in domain to place with increasing successively from centre to both sides spacing, and the quantity of this Pad unit is very large, and spacing is also rule increases progressively.Complete the urgent problem that this operation is also eda tool developer with how can helping user's quickness and high efficiency.

Present stage only copies an object by the copy command in eda tool, the position of expectation can be found to be put down by object by mouse, or revises the position of object by movement (Move) order that instrument provides; If once copy hope to obtain one group of object and can realize by arranging row (row) and arranging the value of (column), but existing instrument copy obtain one group of object time, can only to arrange a spacing (pitch) be spacing between each object is a solid values, or can be called that the object obtained is equally spaced.Like this copy shortage dirigibility, and user to change spacing manually must move each object successively to change the spacing between them.

By the replicate run of group setting spacing, be user copy obtain multiple object time, can arrange the number (Bundle Number) often criticizing object as required, be an equivalence in the spacing of this collection of interior object; By arranging the value of going forward one by one (Pitch Step) often criticizing spacing, that copies out often criticizes object and all can increase successively according to this value of going forward one by one.When copying multiple object like this, user can be made to obtain gap variable one group of object easily.The spacing of every a collection of object is all by adding that value of going forward one by one obtains on the spacing basis of front a collection of object.Such copy mode is particularly important in the layout drawing of flat-panel monitor design (FPD), and user can obtain the object of one group of spacing cumulative (subtracting) easily, and operates and arrange also very easy, substantially increases the ease for use of eda tool.

Summary of the invention

The present invention disclose a kind of according to self-defining often criticize object number and object often criticize between the value of going forward one by one of spacing, be automatically divided into multiple batches by copying the multiple objects obtained, and according to calculating the distance values often criticized in object and place the method for object.

Basic thought: in layout design, when order that use copies (Copy) copies and obtains multiple object, wish that the spacing of each (often criticizing) object is that can set instead of fixing, the domain slip-stick artist that this operation designs for flat-panel monitor is extremely important.When copying multiple object, the target object that selection will copy, arrange and wish to copy the object line number (Rows) obtained, columns (Columns), often criticize the number (Bundle Number) of object and often criticize the value of going forward one by one (Pitch Step) of object spacing, user places the first two object on layout drawing region, the spacing (distance) of these two objects just uses as the spacing of first object, the spacing of second batch object is distance+pitch, the spacing of the 3rd batch of object is distance+2 ﹡ pitch, the like the spacing of n-th batch of object be distance+(n-1) ﹡ pitch.If user wishes that the spacing of each object copying out is not fixing, the number often criticizing object can be set to 1.If the object copying out is an array, the object spacing of horizontal direction and the object spacing of vertical direction calculate respectively, do not have correlativity.

Accompanying drawing explanation

Fig. 1 copies as the optimum configurations interface of multiple figure

Fig. 2 copies the prompting cartoon figure that multiple figure prolongs X-axis placement

Fig. 3 copies multiple figure of generation and often criticizes the spacing of object

Fig. 4 copies and obtains all different exemplary plot of one group of each pattern pitch

The design sketch generating multiple IC Pad is copied in the actual domain of Fig. 5

concrete implementation step:

Illustrate in conjunction with example and copy multiple object and the spacing arranging each object is the method for different value, operating process step is as follows:

1) select a figure, and startup copies (Copy) order, that ejects this order arranges interface (as shown in Figure 1), often organizes the relevant parameter options of object spacing, if shown in territory, Fig. 1 frame settlement with copying as many objects and arranging.

2) arranging row is after 7, and to be 2, Pitch Step be Bundle Number after 0.2, and the position selecting to place figure in drawing area simultaneously eda tool can provide the prompting cartoon figure of the relative position of each figure, as shown in Fig. 2.

3) the position left button that mouse is selected in drawing area is clicked, the figure as shown in prompting cartoon figure can be created out, as shown in Figure 3, can see that the spacing often criticizing object calculates according to the settings of Bundle Number and Pitch Step in the drawings;

4) Bundle Number is set to 1, each pattern pitch copying out can be made to be different value.Such as arranging Pitch Step value is after 0.2, the object copying out and the spacing of object, as shown in Figure 4;

5) in the domain of flat-panel monitor design, in order to offset thermal expansion, the Pad unit be connected can be placed from centre to both sides spacing with increasing successively, as shown in Figure 5 with IC device.

Claims

1., by a method for group setting spacing copy pattern, the principal character relating to EDA design tool is:

(1) by often criticizing the number (Bundle Number) of object and often criticizing the spacing of value of going forward one by one (Pitch Step) these two state modulator objects of object spacing in the copy command of eda tool;

(2) computing method of object spacing: the distance values of first group of object depends on the spacing of the first two object, the spacing often criticizing object is afterwards all that the spacing of front a collection of object adds value of going forward one by one (Pitch Step);

(3) in the layout design of flat-panel monitor, by group Bundle Number Auto-grouping when copying IC Pad unit, and according to the method arrangement IC Pad unit that (2) describe;

(4), in layout design, the unit of copy pattern (comprising Rectangle, Path, Polygon etc.) and Block level can place object according to the method described in (2);

(5) no matter the object copied in domain is to put in the row direction or at column direction, or ranks direction is put simultaneously, and the method for object grouping and setting spacing is all effective.

2. claimed have feature (1).

3. claimed have feature (2).

4. claimed have feature (3).
