Problems solved by technology

The winding algorithm is extremely sensitive to the order of winding, which usually causes the network that is wound first to affect the network that is wound later
[0005] None of the above winding methods can better solve the problem of winding conflict, and in sequential winding, it is necessary to set a better winding order to improve the winding efficiency. The success rate is not very operable in the actual winding process

Embodiment Construction

[0074] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0075] Such as figure 1 The layout automatic routing method based on pre-routing shown mainly includes global routing and detailed routing process, which can effectively solve the problem of routing conflicts in the routing process; this kind of layout automatic routing based on pre-routing The line method specifically includes the following steps:

[0076] Step (1): Initialize the winding information;

[0077] Obtain information about all networks to be routed, the region to be routed, components and obstacles, and set the width and spacing of the routes to be routed, and set the status of the network to be routed to wait.

[0078] The to-be-winded network includes information such as the positions of the two to-be-wound components and the pins to be wound; After the network to be wound to which the pin to be wound belongs completes the wind...

Abstract

The invention relates to an automatic layout winding method and system based on pre-winding, and a storage equipment. The automatic layout winding method specifically comprises the following steps: (1) initializing winding information; (2) creating a switch box; (3) creating a winding track and nodes; creating a winding track to perform grid division on the winding area, and setting intersection points of the winding track as nodes; (4) carrying out global winding; (5) carrying out detailed winding; and carrying out detailed winding processing on all the networks to be wound passing the globalwinding to obtain a winding result. According to the invention, during detailed winding, sparse grids are divided according to winding tracks created by a switch box and pins, the node path exploration efficiency is improved, penalty values of related nodes are increased according to the pins to be wound in a subsequent network to be wound, certain windings are reserved for subsequent winding, and the problem of winding conflicts generated in the winding process can be well solved.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a layout automatic winding method and system based on pre-winding. Background technique [0002] With the development of integrated circuit technology, compared with the problem of low efficiency in traditional manual wiring, computer automatic wiring has shown great advantages in layout design, greatly improving the efficiency of winding. Traditional routing methods mainly include two stages: global routing and detailed routing. The traditional winding method does not have a good solution to the problem of winding conflicts generated during the winding process, which usually causes the first generated winding to block the subsequent generated winding, which eventually leads to winding failure. Traditional routing algorithms are mainly divided into two types: single-network routing and multi-network routing. The main winding methods are as follows: [0003] 1. Lee'...
