Signal declaration system, method and device in digital logic design and medium

Abstract

The invention discloses a signal declaration system, method and device in digital logic design and a medium, and the system comprises design modules which comprise a corresponding writing statement; afile index list which comprises file names corresponding to the design modules; an automatic declaration script which is used for retrieving writing statements in the design module through annotationstatements and determining all to-be-declared signals, and declaring the retrieved to-be-declared signal. By designing the annotation statement in the module, all signals to be declared can be accurately positioned by using the automatic declaration script, declaration is carried out based on the data bit width in the annotation statement, and the accuracy of the data bit width during signal declaration is ensured. The to-be-declared signals of each design module in the design engineering are automatically declared, so that the workload of developers is reduced. And when the related design inthe design module is changed, the declaration of each signal can be completed only by running the automatic declaration script again, so that the method is very convenient.

Description

technical field [0001] The present application relates to the field of signal declaration, in particular to a signal declaration system, method, device and medium in digital logic design. Background technique [0002] At present, the electronic information technology industry is developing rapidly, and the performance requirements for special-purpose chips are getting higher and higher. With the rapid progress of integrated circuit manufacturing technology, the complexity of integrated circuits is increasing exponentially, and the scale of digital logic design is increasing. The number of signals Therefore, it becomes time-consuming and laborious to manually write the signal declarations in each design module, and it is very easy to have problems such as missing declarations and incorrect declaration bit widths. Contents of the invention [0003] In order to solve the above problems, the present application proposes a signal declaration system in digital logic design, incl...
