Abstract

The invention discloses an automatic positioning method for physical short circuit positions among multiple line networks, and belongs to the technical field of electronic design automation. The method comprises the following steps of: receiving a circuit diagram/circuit network table, physical layout data and layout versus schematic (LVS) result data; and establishing an abstract diagram according to the circuit diagram/circuit network table, the physical layout data and the LVS result data, and simplifying the abstract diagram so as to complete automatic positioning of physical connection short circuits of the multiple line networks on the simplified abstract diagram. By using the method, automatic positioning of the physical short circuits among the multiple line networks during integrated circuit physical layout design can be automatically realized to replace a designer to manually seek the physical short circuit positions on the physical layout, so that the design efficiency of the physical layout is improved.

Description

technical field [0001] The invention relates to the technical field of electronic design automation (EDA), in particular to an automatic positioning method for the physical short circuit position between multi-line nets. Background technique [0002] After the physical layout of the integrated circuit is designed according to the circuit diagram, it is necessary to use LVS (physical layout and circuit Figure 1 Consistency) tool checks the consistency between the physical layout and the circuit diagram, and finds out the inconsistencies between the two for modification, so as to finally ensure that the physical layout and the circuit diagram are completely consistent. Physical layout design is a complex and cumbersome work. During the physical layout design process, due to the negligence of designers or defects in software tools, it is easy to cause short circuits between physical connections of different nets, resulting in multiple independent circuits on the circuit diagram...
