Abstract

The invention relates to integrated circuit designs, and discloses a wiring method and a wiring system on the basis of graphics processing units. The wiring method and the wiring system have the advantages that a priority queue which is the core of the traditional wiring method for an integrated circuit is removed by the aid of the super parallel processing capacity of the graphics processing units, wiring search is carried out by means of simultaneously monitoring states of nodes in a wiring resource map instead, accordingly, the wiring time is only relevant to the length of a wiring path and is irrelevant to the size of wiring space, hundreds of processing units can be utilized for wiring for single connection, and the wiring speed is far higher than that of any other currently known methods without sacrificing the resulting performance of the integral system; and integral wiring is divided into global wiring and detailed wiring, the integral wiring speed is further increased, and internal memories of the graphics processing units are sufficient to meet application requirements of current super-large-scale integrated circuits.

Description

technical field [0001] The invention relates to the field of integrated circuit design, in particular to an integrated circuit wiring method and system thereof. Background technique [0002] In ASIC routing systems and programmable logic device routing systems, routing is usually the most time-consuming part of the entire IC physical design process because the number of devices to be processed can be as high as tens of millions. In practical applications, it often takes several days for the wiring system to complete the wiring of a network of millions of wires. In all current wiring technologies, the connection speed of a single line network is related to the size of the wiring resource map of the integrated circuit chip. The larger and more complex the circuit, the slower the wiring speed. [0003] Among the wiring schemes of integrated circuits, the most widely used ones are the Lee’s Maze wiring system (Lee’s Maze) and the improved A * wiring system, and without losing ...
