A method of converting a synchronization circuit into an asynchronous circuit

Abstract

According to the invention, a synchronous assembly line circuit can be automatically converted into a Click unit-based bundled data asynchronous circuit. According to the method, firstly, by comparingthe difference between a synchronous assembly line and a Click unit-based binding data asynchronous circuit, a synchronous Verilog code is converted into a Verilog code of the Click unit-based binding data asynchronous circuit through a Tcl script; and then, the asynchronous circuit is integrated through a Synopsys Designn Compill (DC) tool. According to the invention, the synchronous pipeline circuit can be quickly converted into the Click-based bundled data asynchronous circuit, so that the design period of the asynchronous circuit is greatly shortened and the design difficulty of the asynchronous circuit is reduced.

Description

technical field [0001] The invention belongs to the technical field of integrated circuit design, in particular to a method for converting a synchronous circuit into an asynchronous circuit. Background technique [0002] With the continuous improvement of integrated circuit manufacturing technology, asynchronous circuits have the following significant characteristics compared with synchronous circuits. [0003] 1. Low power consumption: asynchronous circuits only consume power when and where they are needed [0004] 2. High speed: the delay of an asynchronous circuit depends on the local delay rather than the longest delay path of the overall circuit [0005] 3. No clock distribution problem: asynchronous circuits do not have a global clock, so no clock tree synthesis is required [0006] However, the design of asynchronous circuits is more difficult. Since asynchronous circuits have not been widely adopted by the industry, there are no mature commercial EDA tools to supp...

AI Technical Summary

Problems solved by technology

[0005] 3. No clock distribution problem: asynchronous circuits do not have a global clock, so no clock tree synthesis is required

[0006] However, the design of asynchronous circuits is more difficult

Since asynchronous circuits are not widely adopted by the industry, there are no mature commercial EDA tools to support the design of asynchronous circuits

In addition, since many integrated circuit digital engineers receive training in synchronous circuit design, there is a problem of switching from synchronous circuit design thinking to asynchronous circuit design thinking in design, which increases the burden of asynchronous circuit design. difficulty

Finally, there are many types of asynchronous circuits, and there are differences in the design methods of different types of asynchronous circuits, which also raises the threshold of asynchronous circuit design to a certain extent.
