Point-to-line cross-obstacle wiring method in special-shaped layouts

Abstract

The invention discloses a point-to-line cross-obstacle wiring method in special-shaped layouts. The method comprises the following steps of: starting a cross-obstacle wiring command according to a geometric constraint, and setting a wiring parameter; constructing a grid map according to the wiring parameter set by a user; selecting a port and a bus for carrying out a wiring operation; completing wiring according to a design requirement; determining a datum point of the bus, obtaining a section of continuous point link by taking the datum point as a center point and taking a threshold value asa neighborhood, and taking the continuous point link as a connection port area of the bus; and continuously and repeatedly executing above steps to complete wiring between other groups of ports. According to the point-to-line cross-obstacle wiring method in special-shaped layouts, the point-to-line cross-obstacle wiring problems in special-shaped layouts are solved, the wiring forms are reasonable, and thousands of groups of ports can be processed at one time.

Description

technical field [0001] The invention relates to the technical field of electronic design automation (EDA), in particular to a point-to-line cross-obstacle wiring method in a special-shaped layout. Background technique [0002] In the field of special-shaped panel design, connections need to be made between the pixel units in the AA area and the power bus, between cells such as multiplexers and GOA drive units, and the signal bus and power bus. These routing environments are generally more complex, requiring routing to have the ability to cross obstacles, and also to meet the geometric constraints of the design. In addition, there are a large number of point-to-line ports, such as Apple Watch, which has a size of 38 mm or 42 mm. In this size, the number of point-to-line wiring is on the order of several thousand. Manual connection must be Inefficient and error-prone. The method often used in the industry is to create instances for the same environment to reduce the workload...

In addition, there are a large number of point-to-line ports, such as Apple Watch, which has a size of 38 mm or 42 mm. In this size, the number of point-to-line wiring is on the order of several thousand. Manual connection must be inefficient and error-prone

The method often used in the industry is to make instances for the same environment to reduce the workload, but it still takes a lot of time to lead, so the point-to-line router that supports barriers is an urgent function for design manufacturers
