Abstract

The present invention discloses a kind of amending method of integrated circuit diagram figure.The present invention can generate absorption point according to projection of the cursor of mouse on original figure, and absorption point has prompted the boundary intersection of original figure and new figure；The present invention also uses shortcut key, the line segment between auto-complete cursor of mouse and absorption point, quick end operation.This graphics shape amending method can greatly improve order and execute speed, reduce a large amount of domain amplification, diminution and clicking operation, improve the efficiency for drawing domain.

Description

A kind of amending method of integrated circuit diagram figure

Technical field

Modification integrated circuit diagram figure refers to adjusting on the basis of original figure new to obtain in eda tool The process of figure.The invention belongs to layout design fields in eda tool.

Background technology

Layout design is step mostly important, the most key in IC design, directly decides that entire chip is set The success or failure of meter.With the progress of IC manufacturing process, characteristic size is smaller and smaller, and desin speed is getting faster, layout design also phase It should become increasingly complex.

During IC Layout, it is often necessary to be made an amendment on the basis of original figure, this process quilt Referred to as Reshape.Reshape needs to rely on the boundary of original figure again sometimes, this just often requires that engineer is executing The amplification and diminution that domain is ceaselessly carried out when Reshape to click the borderline point of original figure, and select new boundary Constantly to estimate newly to put the relative position relation with original figure boundary when vertex.This process is very time-consuming, laborious, especially when Domain is larger, comparatively dense when, operation will be very difficult.

Invention content

The present invention discloses a kind of amending method of integrated circuit diagram figure, by prompting, creating new figure and original graph The modification process of figure, more convenient, the more hommization of intelligence of such operating method is rapidly completed in the mode of the crosspoint of shape.

After starting Reshape orders, automatic absorbing starting point.It automatically creates by the cartoon of mouse to targeted graphical, it should Cartoon is by mouse, projection of the automatic absorbing to cursor of mouse on original figure.So there is no need to first amplify domain The process for clicking starting point on to the boundary of figure again, can efficiently select starting point.

In mouse moving process, cartoon is adsorbed on the boundary of original figure at any time.In this way, can see that mouse exists at any time Projection on original figure facilitates the relative position relation of determining new summit and original figure, when shortening the selection of graphics vertex Between；

In addition, when executing to when selecting the last one vertex, by the way of shortcut key, auto-complete by cursor of mouse and Line segment between cartoon absorption point, quickly terminates order, and no longer need by amplify domain click again to graphic limit vertex this The troublesome operation of sample makes operation become time saving and energy saving.

Description of the drawings

Fig. 1 Reshape options.

Fig. 2 Reshape adsorb starting point design sketch.

Fig. 3 Reshape prompt the crosspoint of new figure and original figure.

Fig. 4 Reshape keyboard shortcut completions boundary.

Specific implementation step：

Illustrate the method for Reshape in conjunction with two specific examples,

1, the starting point of Reshape figures is determined using automatic absorbing, steps are as follows for operating process：

1）Select the figure to be changed.

2）Start Reshape, cartoon is at this moment created by mouse, cartoon automatic absorbing to cursor of mouse is on original figure Subpoint.

2, the terminating point of Reshape figures is determined using automatic absorbing point, steps are as follows for operating process：

1）Start Reshape orders, and selects the figure to be changed.

When needing to select last vertex, mobile mouse makes cartoon absorption point be moved to target location, automatic by shortcut key Line segment between completion cursor of mouse and absorption point, completes order.

Claims

1. a kind of method on the automatic absorbing boundary during integrated circuit diagram diagram shape modification, includes the following steps：

(1) in the modification of integrated circuit diagram figure, automatic absorbing starting point；

(2) in the modification of integrated circuit diagram figure, as mouse moves, absorption point is constantly updated, new figure and original graph are prompted The crosspoint of shape；

(3) it in the modification of integrated circuit diagram figure, by shortcut key, automatically creates by cursor of mouse to the line segment between absorption point, Determine the ultimate bound of figure；

Wherein, automatic absorbing starting point refers to automatically creating by the cartoon of mouse to targeted graphical in the step (1), the cartoon By mouse, projection of the automatic absorbing to cursor of mouse on original figure.
