Netlist ECO method and device, equipment and readable storage medium

Abstract

The invention provides a netlist ECO method and device, equipment and a readable storage medium. The method comprises the following steps: carrying out the function modification of an original behavior-level code set according to a modification demand, modifying an original netlist set according to a first ECO script, obtaining a modified behavior-level code set and a modified netlist set, extracting a modification layer code and a modification layer netlist, and performing modification layer logic equivalence verification according to the obtained target modification module behavior-level code and the target modification module gate-level netlist; and if the modification layer logic equivalence verification result is consistent, sending the first ECO script to the IC back end for operation. In the debugging stage, only the codes of the modified part and the netlist need to be compared, logic equivalence verification is carried out, due to the fact that the data size of the local code module is small, debugging debugging can be rapidly completed, the ECO script debugging efficiency is improved, and the ECO script debugging time and the whole IC design process time are shortened.

Description

technical field [0001] The present application relates to the technical field of integrated circuit design, in particular to a netlist ECO method, device, equipment and readable storage medium. Background technique [0002] In circuit design, a netlist is used to describe the connection relationship between circuit components, generally speaking, it is a text file that follows a relatively simple markup syntax. For complex integrated circuit design, circuit functions need to be described through multiple levels, including RTL behavior description, and the modeling of its behavior is carried out by describing the signal behavior level. [0003] Engineering Change Order (Engineering Change Order, ECO) refers to finding an error at a certain stage in the process, and directly changing the design of the current process stage without repeating the whole process, so as to reduce the repetition of the whole process. The extension of the project time. Netlist ECO is the process of...

Problems solved by technology

Netlist ECO is the process of manually modifying the gate-level netlist. Since the IC backend has been designed in the later stage of chip design, the gate-level netlist cannot be re-synthesized. If the gate-level netlist is re-synthesized, it will cause back-end work All obsolete, so patching is only allowed on existing gate-level netlists

[0004] During the process of conceiving and implementing this application, the inventors found at least the following problems: For large-scale digital desi
