Method for creating rectangle in layout design

Abstract

The embodiment of the invention provides a method for creating rectangle in layout design. The method comprises the steps that information of a layer where a detected object is located is determined; judging whether the layer where the object is located is an activated layer according to the layer information; if yes, searching geometric figures in the drawing area of the layer based on the position of the mouse point; judging whether the edge is an orthogonal edge or not according to the starting point and the ending point of the edge in the geometric figure; if the edge is the orthogonal edge, highlighting the orthogonal edge; according to a click event on the orthogonal edge, taking the orthogonal edge as an edge used for creating rectangle; on the basis of the click position of the click event on the orthogonal edge, a second point needed for creating the rectangle is determined, and the position of the second point is determined according to the size of the created rectangle; whether the layer where the object is located is a snap layer or not is judged; if yes, the second point is adsorbed to the grid point of the snap layer, and the position of the second point is updated; according to the position of the second point and the direction of the orthogonal edge, rectangle is created, the layout design process is simplified, and the operation process is not tedious.

Description

technical field [0001] The present application relates to the technical field of circuit processing, and in particular, to a method for creating a rectangle in layout design. Background technique [0002] In the layout design, it is usually necessary to design a rectangle (ie, rectangle). Due to the complexity of the layout design, when designing a rectangle, for the designers, it is faster to create a Rectangle that conforms to the high-end process, thereby improving the work efficiency of the designers. , meeting the precision requirements of advanced technology has become one of the important goals. [0003] In the prior art, in the layout design tool (including but not limited to EDA, the full name of EDA is Electronic designautomation, the Chinese interpretation is electronic design automation tool), the process of designing the rectangle is roughly: load the real-time cartoon according to the mouse point clicked by the user. effect, and create a Rectangle that meets t...

[0003] In the prior art, in the layout design tools (including but not limited to EDA, the full name of EDA is Electronic design automation, which is interpreted as electronic design automation tool in Chinese), the process of designing the rectangle is roughly as follows: load the real-time cartoon according to the mouse point clicked by the user effect, and create a Rectangle that meets the needs of the user after double-clicking the mouse, and after creating the Rectangle, it is necessary to perform multiple Align (alignment) operations to truly complete the design of the rectangle, which leads to a cumbersome design process and low efficiency
