Abstract

In one embodiment, a wiring design method is disclosed. In the wiring design method, schematic wiring is performed on a substrate, and the substrate includes a first wiring layer with first-direction wiring lines and a second wiring layer with second-direction wiring lines; the substrate is divided into a plurality of tiles; the first wiring layer is divided into partial wiring regions with first-direction wiring lines, the second wiring layer is divided into partial wiring regions with second-direction wiring lines, and each partial wiring region corresponds to the tiles; and when the first-direction wiring lines in the tile overflow, the partial wiring region with second-direction wiring lines corresponding to the tile is changed to the partial wiring region with first-direction wiring lines.

Dependent claims

A method for determining a schematic wiring design, implemented on a computer device, comprising:

dividing a substrate into a plurality of tiles, the substrate comprising a first wiring layer and a second wiring layer, the first wiring layer comprising a first plurality of wiring lines and the second wiring layer comprising a second plurality of wiring lines;
dividing a portion of the first wiring layer into a first plurality of partial wiring regions;
dividing a portion of the second wiring layer into a second plurality of partial wiring regions;
determining that a number of the wiring lines of the first and second pluralities of wiring lines oriented in a first direction in the tile exceeds a threshold;
and
modifying the wiring direction of a partial wiring region of the first plurality of wiring regions from a second direction to the first direction.
