Abstract

The invention provides a redundant metal filling method, device and equipment, and a computer readable storage medium. The method comprises the steps of obtaining a to-be-filled integrated circuit layout; wherein the time sequence of the integrated circuit layout is converged; screening out a signal path sensitive to the filling metal from a design circuit of the integrated circuit layout; acquiring physical information of the signal path; according to physical design requirements and the physical information, obtaining a customized layer area forbidden to be filled with redundant metal in theintegrated circuit layout; and performing redundant metal filling on areas, except the customized layer area, in the integrated circuit layout. According to the invention, coupling noise between a signal path sensitive to redundant metal filling and the redundant metal filling can be weakened.

Description

technical field [0001] The invention relates to the technical field of integrated circuit physical design, in particular to a redundant metal filling method, device, equipment and computer-readable storage medium. Background technique [0002] In the field of integrated circuit physical design, after the physical convergence of the module design is completed, redundant metal filling is required on the surface of the design module to improve the wiring uniformity of the layout metal layer, so that the chemical mechanical polishing (CMP, Chemical Mechanical Polishing) morphology More flat, improve product reliability and yield. The principle of redundant metal filling is to fill the vacant area around the circuit physical connection with redundant metal that is not electrically connected to the metal line to change the density of the metal pattern, thereby improving the uniformity of the pattern density of the layout and improving the flatness and electrical conductivity of th...
