Problems solved by technology

Because the steady-state output of the logic unit is only related to the input data signal, that is, in the timing path, the logic unit is only equivalent to the node transmitting the data signal, so in some cases, the data flow between the logic units and the logic unit The data flow b

Abstract

A circuit and a configuration method thereof are provided. The circuit comprising a plurality of modules and the configuration method thereof comprises that one of the plurality of modules is used asa first-stage module; the modules except the first-stage module are used as first residual modules; and the number of connecting lines of the boundary time sequence units in the first-stage module andthe first residual modules are obtained, the number of the connecting lines of the first-stage module and the first residual modules are compared, the first residual module with the largest number ofconnecting lines with the first-stage module is selected as a second-stage module, and the second-stage module is configured to be adjacent to the first-stage module.

Description

technical field [0001] The invention relates to a circuit and its configuration method, in particular to a circuit and its configuration method configured based on the number of connected sequential units on the boundary between modules. Background technique [0002] In terms of existing technologies, front-end engineers can provide a rough data flow, but the data flow provided by front-end engineers is subject to the front-end engineer's understanding of the design and his own experience. The physical implementation tool can also provide data flow, but the data flow provided by the physical implementation tool includes the data cloud in the analysis and the interconnection relationship of all other modules, with much interference information. Therefore, if the timing path analysis between modules is performed based on the data flow of these prior art, the analysis result will fail to meet the requirements of engineering design in terms of accuracy, real-time performance and...
