The invention relates to the technical field of
integrated circuit design, in particular to a character
string processing system for
integrated circuit design, which is used for solving the problems that the prior art cannot cover a multi-layer semantic graph of structure, behavior and function levels, cannot realize four-dimensional classification
annotation of signals in hardware design, and cannot realize multi-layer semantic graph
annotation of structure, behavior and function levels. Design intention labels cannot be extracted by combining naming,
annotation and structural context, and the structural expression ability of
design information and intention recognition precision cannot be improved. A structure, behavior and function three-level
semantic map is constructed through the semantic intention analysis module, four-dimensional classification labeling of signals in hardware design is achieved, design intention labels are extracted in combination with naming, annotation and structure context, paths are divided into data, control, reset and
time sequence types, a clear basis is provided for
verification and optimization, and the method has the advantages of being high in practicability and easy to popularize. The structural expression ability and intention recognition precision of
design information are comprehensively improved, and efficient
collaboration of automatic analysis and a tool chain is supported.
