Asynchronous circuit physical implementation method and system

Abstract

The invention discloses an asynchronous circuit physical implementation method and system, and the method comprises the steps: performing a data preparation stage: importing comprehensive data, physical data and a file for interrupting a combinational logic ring; in the design planning stage, inputting an IO pin constraint file; in the layout stage, carrying out false path constraint on IO; in the wiring stage, carrying out global wiring, wiring channel distribution, detailed wiring and wiring repair on the signal lines; in the manufacturability design stage, the antenna effect problem, the chip density non-uniformity problem and the metal density problem are solved; exporting design data, performing post-simulation, and returning to the manufacturability design stage for processing if errors occur in simulation; and performing physical verification on the exported gate-level netlist and the physical layout. The invention provides a novel asynchronous circuit physical implementation scheme, which can realize the physical design of a large-scale asynchronous integrated circuit based on a synchronous design tool, is compatible with the current synchronous circuit design process, and can be widely applied to the technical field of integrated circuits.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a physical realization method and system of an asynchronous circuit. Background technique [0002] The research on asynchronous circuits first began in the mid-1950s, but the development speed was relatively slow. On the one hand, the design process was not standardized and perfect, and on the other hand, there was no support from mature commercial EDA tools. Synchronous circuits were developed in These two aspects are very advantageous. For example, Synopsys has a complete set of design tools corresponding to the design process of synchronous circuits, and related electronic design automation (Electronic Design Automation, EDA) tools will also be continuously updated to meet new process node requirements. Although asynchronous circuits can solve many problems of synchronous circuits, due to the above reasons, in the field of integrated circuit design, the market shar...

Problems solved by technology

[0004] Although there are some EDA tools for asynchronous circuit design, such as Balsa of the University of Manchester, there are also various asynchronous circuit design methods, such as full-custom design methods, but as the scale of asynchronous integrated circuits becomes larger and larger, These tools and methods are difficult to apply

At the same time, the technical update of asynchronous circuits is also difficult to keep up with the development of technology
