Abstract

The invention provides a method and device for generating a data path according to a bit value. The method comprises the following steps: representing options of all functional modules on a user interface, wherein each functional module is endued with different bit values correspondingly; summing the bit values corresponding to the selected functional modules according to the options of the functional modules selected by a user; performing logical and calculation on the calculated sum of the bit values with the bit value corresponding to each functional module respectively; and when the calculation result is not zero, driving to open a data path of the functional module corresponding to the current bit value, and generating a path link. By using the method and the device, various path links required by users can be quickly generated, the verification efficiency of chips is improved, and user operation is intuitive and clear.

Description

technical field [0001] The invention relates to the technical field of integrated circuits, in particular to a method and device for generating data paths according to bit values. Background technique [0002] A chip is a circuit module that integrates a variety of electronic components on a silicon board to achieve a specific function. It is the most important part of electronic equipment and undertakes functions such as computing and storage. Its application range covers almost all military and civilian applications. electronic equipment. With the development and progress of science and technology, the functions of chips are becoming more and more powerful, and different processing functions correspond to different data paths. For the current chips, there are many integrated data paths, and a PC Camera chip has hundreds of paths. For example, SIF can output YUV data or RGB data. Image signal processor (ISP) can choose whether to use ISP1 or ISP2, and IPP can choose YUV42...
