Multi-level netlist processing method, device, computer equipment and storage medium

Abstract

The invention discloses a multi-layer hierarchical netlist processing method, a device, equipment and a medium. The method comprises the steps of acquiring hardware circuit design, and generating a multi-layer hierarchical netlist based on the hardware circuit design; analyzing the multi-layer hierarchical netlist to generate a corresponding module call relationship tree, the module call relationship tree comprising an upper-layer hierarchical module, a lower-layer hierarchical module and an inter-module call relationship, and each upper-layer hierarchical module comprising at least one moduleinstantiation object; and according to the inter-module calling relationship, sequentially replacing each module instantiation object with a lower-layer hierarchical module, and inserting a virtual node storing module information into the connection position of the lower-layer hierarchical module and the upper-layer hierarchical module to obtain a target single-layer netlist. According to the method, the problem of high netlist processing complexity or netlist information loss in the netlist construction process of the current multi-layer structure design is solved.
