Abstract

The invention provides a chip wiring method, comprising: obtaining the congested area of ​​wiring congestion on the chip by laying out and wiring the chip; obtaining multiple standard units in the congested area; Adjusting the position of the unit can improve the wiring efficiency of the chip while eliminating wiring congestion.

Description

technical field [0001] The invention relates to the technical field of integrated circuit design, in particular to a chip wiring method. Background technique [0002] In the physical design of integrated circuits, the full utilization of wiring resources can reduce the area of ​​the chip, thereby greatly reducing the cost of the chip and improving the competitiveness of this product in the market. At present, the development of various layout and routing tools is more and more complete, which not only improves the speed of chip design, but also greatly improves the utilization rate of routing resources. However, the placement and routing tools usually take the global chip as the consideration, and it is inevitable that some small points are not considered carefully, and some local congestion will occur during the actual placement and routing process, for example, the area close to the pins of the macrocell (block) (pin) and areas near the corners of the block, etc. At this...
