Abstract

An interactive wiring method comprises the following steps: 1) setting interactive wiring parameters; 2) selecting a connection graph, generating a connection point according to the graph attribute, and selecting a wiring width; 3) selecting a turning point and a jump layer obstacle avoidance point for orthogonal and oblique wiring; and 4) determining the wiring result and performing interactive wiring. According to the interactive wiring method, the graph of the starting point can be automatically detected, and the hierarchy and the width of the interactive wiring can be dynamically set, andthe starting point of the interactive wiring can be adjusted, and the consistency of the interactive wiring can be guaranteed, and the manufacturing requirement can be met.

Description

technical field [0001] The invention relates to the technical field of EDA design, in particular to a wiring method in an integrated circuit layout. Background technique [0002] With the advancement of technology, the ultra-deep sub-micron technology has been continuously improved, and the chip density has been continuously increased while the chip area is reduced. Wiring is the final link of physical design in VLSI, and the result of wiring plays a vital role in the chip, which makes the application of EDA (Electronic Design Automation) tools an indispensable auxiliary means. [0003] Wiring refers to the allocation of metal lines between the units to be connected, pins or other electronic devices in the physical design stage, and the metal lines of different connection relationships cannot overlap. In addition, it must meet a large number of geometric requirements in physical design constraint. With the maturity of lithography process and the improvement of chip perform...
