Abstract

The invention discloses an automatic wiring method and device for a chip top layer long and narrow channel and a storage medium. The method comprises the steps: arranging a first wiring buffer area at the corner where a transverse channel and a longitudinal channel of a channel to be wired are connected, wherein a plurality of buffer units are arranged in the wiring buffer area, and each signal pin to be wired corresponds to one buffer unit; performing automatic wiring according to the plurality of buffer units, wherein during automatic wiring, transverse wires of all the signal pins are parallel to the edge of the transverse channel, and longitudinal wires perpendicular to the transverse wires are arranged at the positions, corresponding to the signal pins, of the buffer units. By implementing the embodiment of the invention, the problem of winding congestion during automatic wiring in a long and narrow channel in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of chip design, in particular to an automatic wiring method, device and storage medium for a long and narrow channel on the top layer of a chip. Background technique [0002] With the further expansion of the scale of integrated circuits and the gradual reduction of the size of process nodes, more and more chips will adopt multi-level implementation methods in the physical implementation stage. The common ones are two-layer or three-layer design structures. The advantages of multi-level design structures Modules at all levels are implemented in parallel, so as to improve the implementation efficiency of the chip physical design stage. When dividing the multi-level structure, it is necessary to consider the logical size, functional complexity and physical realizability of the individual modules to be divided. The highest level is also called the top level. The top level generally retains the chip input and o...
