Problems solved by technology

The problem arising from this working mode is that with the increase in the scale and complexity of chip design, the workload of data transfer and integration in the later stages of the teams in each design link will increase sharply, and the back-end design engineers must master multiple designs at the same time. tool
There are problems of low work efficiency, high design threshold, and high labor costs, which lead to a great discount in the progress and design quality of chip projects

Abstract

The invention discloses an integrated circuit back end design system. The system comprises an environment building module, a design task module, a layout planning design module, an automatic unit placement optimization module, a clock tree synthesis optimization module, a global routing optimization module, a functional equivalence checking module, a timing sign-off design module, a voltage attenuation design module and a physical verification module. According to the integrated circuit back end design system, design sequence standardization is carried out on the main design links of the backend design, so that the design has good universality, thus the design threshold of the back end design is greatly reduced, the labor cost is reduced, the design efficiency is improved, and the designquality is ensured.

Description

technical field [0001] The invention relates to the technical field of integrated circuit design, in particular to an integrated circuit backend design system and an integrated circuit backend design method realized by using the design system. Background technique [0002] At present, in the process of layout design of integrated circuits, the design process is very complicated due to the long design process of the back-end of the integrated circuit and many design links. In the industry, teams in different design links are generally used as units to independently complete the corresponding designs, and then transfer and integrate the design data of each team in the corresponding links of the back-end design, and finally complete the entire design. The problem arising from this working mode is that with the increase in the scale and complexity of chip design, the workload of data transfer and integration in the later stages of the teams in each design link will increase sh...
