[0002] When chip backend engineers use EDA (Electronic Design Automation) software to design chip physical layout, they need to load a large number of technical library files. These files include important information such as physical information and timing information of the basic logic units of the chip, which are the basis for chip backend design. These files are often generated in a relatively fixed syntax format and stored in the form of text files. However, the file formats used by different chip processes and design companies are often not completely standardized, but there are certain differences from the standard format. In addition, during the chip design process, library files need to be replaced according to some special requirements, which makes it inconvenient to extract and manage information from library files. In addition, as chip process updates and iterations become faster and faster, the number of library files often increases, and the industry's demand for an efficient library file management mode is increasing. Therefore, how to improve the efficiency of information search in the electronic automation design file library has become a technical issue that cannot be underestimated. Summary of the invention

[0044] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0045] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of information search technology.

[0046] According to research, when chip backend engineers use EDA (Electronic Design Automation) software to design chip physical layout, they need to load a large number of technical library files. These files include important information such as physical information and timing information of the basic logic units of the chip, which is the basis for chip backend design. These files are often generated in a relatively fixed syntax format and stored in the form of text files. However, the file formats used by different chip processes and design companies are often not completely standardized, but there are certain differences from the standard format. In addition, during the chip design process, library files need to be replaced according to some special requirements, which makes it inconvenient to extract and manage information from library files. In addition, as chip process updates and iterations become faster and faster, the number of library files often increases, and the industry's demand for an efficient library file management mode is increasing. Therefore, how to improve the efficiency of information search in the electronic automation design file library has become a technical issue that cannot be underestimated.

[0047] Based on this, an embodiment of the present application provides an information search method for an electronic automation design file library. By constructing a syntax tree structure using a DSL implemented by the YAML coding language, the storage structure and extraction mode of key information in the file library are hierarchically expressed, and the separation of reading content and processing logic is achieved, which makes it convenient for users to search for the information to be read as needed during use, thereby improving the accuracy and efficiency of information search.

[0048] See also Figure 1 , Figure 1This is one of the flow charts of a method for searching information in an electronic automation design file library provided in an embodiment of the present application. Figure 1 As shown in , the information search method provided by the embodiment of the present application includes:

[0049] S101: performing DSL configuration definition on content information and regular expressions of each file in the electronic automation design file library based on the YAML writing language, and generating an abstract syntax tree of the electronic automation design file library.

[0050] In this step, the content information of each file in the electronic automation design file library and multiple regular expressions corresponding to each file are defined by DSL configuration according to the YAML writing language to generate an abstract syntax tree of the electronic automation design file library.

[0051] Among them, DSL (Domain-specific Language) is a language applied in the context of a specific domain, which can efficiently solve problems in the applicable domain. When the vocabulary and grammar are specified in detail, DSL can concisely express relatively complex meanings. Serialization languages ​​such as YAML can clearly define structures with obvious hierarchical relationships, which are suitable for defining the hierarchical relationships of EDA library files and completing information extraction and analysis.

[0052] In a possible implementation, a DSL configuration definition is performed on the content information and regular expression of each file in the electronic automation design file library based on the YAML writing language to generate an abstract syntax tree of the electronic automation design file library, including:

[0053] A: Perform DSL configuration on the content information of the file based on the YAML writing language to generate key nodes.

[0054] Here, the content information of the file is configured with DSL according to the YAML writing language to generate key nodes.

[0055] B: Perform DSL configuration on the attribute information of the content information based on the YAML writing language to generate attribute sub-nodes; wherein the attribute information includes format storage information, display information and regular expression information.

[0056] Here, the attribute information of the content information is configured with DSL according to the YAML writing language to generate attribute sub-nodes.

[0057] Among them, the regular expressions of each node in a file used in the initial configuration are the same.

[0058] Among them, the attribute subnode is the child node of the key node. In the YAML configuration, the key node can be used to define a new node, and the attribute subnode can define the attributes of each node. In addition, the key node can also be used as an attribute subnode. For example, the node defined by the key node is considered to be an attribute information (subnode) of the upper node. When reading a file, the node defined by the key node is stored in the form of a key-value pair (for the presence of child nodes, the value may be a dictionary consisting of a series of other key-value pairs), and the attribute subnode defines the behavior of the file content extraction function when processing the file content.

[0059] C: constructing a DSL structure with the plurality of key nodes and the plurality of attribute sub-nodes, and processing the DSL structure to generate an abstract syntax tree divided into levels.

[0060] Here, a DSL structure is formed by a plurality of nodes and a plurality of sub-nodes, the DSL structure is processed, an abstract syntax tree divided into levels is generated, and the abstract syntax tree is cached.

[0061] In the present application, the logic and configuration are separated, and the content information of the read file, the format in which the content information is stored, and the display format of the read result can all be customized by the user by modifying the DSL configuration file.

[0062] S102: traverse and read the abstract syntax tree based on a first information search request of a target user, and determine a target file corresponding to the first information search request in the abstract syntax tree and a first initialization regular expression group of the target file.

[0063] In this step, the syntax tree is traversed and read according to the first information search request of the target user, and the target file corresponding to the first information search request in the abstract syntax tree and the first initialization regular expression group of the target file are determined.

[0064] The first initialization regular expression group is composed of a plurality of regular expressions.

[0065] In a possible implementation manner, the traversing and reading the abstract syntax tree based on the first information search request of the target user, determining the target file corresponding to the first information search request in the abstract syntax tree and the first initialization regular expression group of the target file, includes:

[0066] (1): Based on the first information search request of the target user, the abstract syntax tree is read to determine a plurality of target key nodes of the target file corresponding to the first information search request in the abstract syntax tree and target attribute subnodes of the target key nodes.

[0067] Here, the abstract syntax tree is read according to the first information search request of the target user, and a target key node corresponding to the first information search request in the abstract syntax tree is determined.

[0068] (2): Based on the target attribute sub-node, determine the first initialization regular expression group.

[0069] Here, a first initialization regular expression group is determined according to the target attribute child node.

[0070] S103: merging the first initialization regular expression group to generate a composite regular expression group, performing information matching on the target file based on the composite regular expression group, and if the match is successful, determining an information search result, and displaying the information search result to the target user.

[0071] In this step, the first initialization regular expression group is merged to generate a composite regular expression group, and information matching is performed on the target file according to the composite regular expression group. If the match is successful, the information search result is determined and displayed to the target user.

[0072] Among them, since there are more than one regular expressions that need to be matched for each line of file content, if traversal is performed for matching, the number of regular matches will be greatly increased, and the total number may reach more than ten times the number of file lines, which has a great impact on the computing performance. Therefore, before performing regular matching, the present invention first synthesizes all regular expressions that need to be matched into a composite regular expression and compiles it into a Pattern object, and then uses the composite expression for matching. For example, the regular expressions are a(\d+), b(\d+), c(\d+) and d(\d+), respectively, then the composite regular expression group is: P=(a(\d+))|(b(\d+))|(c(\d+))|(d(\d+)).

[0073] In a possible implementation manner, performing information matching on the target file based on the compound regular expression group and determining an information search result if the match is successful includes:

[0074] i: Based on the compound regular expression group, each line of content information of the target file is traversed and matched according to the first information search request, and matching content corresponding to the expression sequence of the compound regular expression group is determined; wherein the expression sequence is the arrangement order of each regular expression in the first initialization regular expression group.

[0075] Here, each line of content information of the target file is traversed and matched according to the compound regular expression group according to the first information search request to determine the matching content corresponding to the expression sequence of the compound regular expression group.

[0076] The expression sequence is the arrangement order of each regular expression in the first initialization regular expression group.

[0077] Here, the matching content is the matching content corresponding to each regular expression in the compound regular expression group. For example, if the above compound regular expression group p is used to match each line of the read file, the matching content in the return value of Python's re.findall method corresponds to the query result of each regular expression, and the position in the return value is also different. The position depends on the number of capture groups in the expression. Therefore, you only need to know the sequence of expressions in the DSL to calculate the unique correspondence between the position of non-empty content in the matching result and the specific regular expression.

[0078] ii: If the matching contents corresponding to the expression sequence are all empty, the matching fails, and the content information of the target file is matched again.

[0079] Here, if the matching contents corresponding to the expression sequence are all empty, the matching fails, and the content information of the target file is matched again.

[0080] iii: If any of the matching contents corresponding to the expression sequence is not empty, the match is successful and the information search result is determined.

[0081] Here, if any of the matching contents corresponding to the expression sequence is not empty, the match is successful and the information search result is determined.

[0082] In a possible implementation manner, the first initialization regular expression group is merged to generate a composite regular expression group, and information matching is performed on the target file based on the composite regular expression group. If the match is successful, after determining the information search result, the information search method further includes:

[0083] I: storing the merged first initialization regular expression group, the matching contents corresponding to the expression sequences of the compound regular expression group, and the compound regular expression group in a database.

[0084] Here, the combined first initialization regular expression group, the matching contents corresponding to the expression sequence of the compound regular expression group, and the compound regular expression group are stored in a database.

[0085] II: Detect whether the second information search request of the target file and the second initialization regular expression group corresponding to the second information search request are consistent with the first information search request and the first initialization regular expression group.

[0086] Here, it is detected whether the second information search request of the target file and the second initialization regular expression group corresponding to the second information search request are consistent with the first information search request and the first initialization regular expression group.

[0087] III: If so, the information search result corresponding to the compound regular expression is used as the information search result of the second information search request.

[0088] Here, if they are consistent, the information search result corresponding to the compound regular expression is directly used as the information search result of the second information search request, without the need to calculate the corresponding relationship or merge the expressions, but only to extract from the database.

[0089] In this application, a compound regular expression group is used for matching, and then which independent regular expression matches the relevant content is determined based on the matching results. Test results show that the time taken for compound regular expression group matching is much less than that of each regular expression in the original initialization regular expression group being matched independently, and the expression groups used for matching and their corresponding compound expressions are cached in memory as Python dictionaries to avoid repeated regular expression merging and compilation operations.

[0090] In a possible implementation manner, after merging the first initialization regular expression group to generate a composite regular expression group, performing information matching on the target file based on the composite regular expression group, and determining the information search result if the match is successful, the information search method further includes:

[0091] (I): Determine the target key node of the information search result in the abstract syntax tree.

[0092] (ii): deleting the determined regular expression in the first initialization regular expression group of the target key node to complete the update of the first initialization regular expression group of the target key node; wherein the determined regular expression is the regular expression corresponding to the information search result.

[0093] Here, the determined regular expressions in the first initialization regular expression group of the target key node are deleted to complete the update of the first initialization regular expression group of the target key node, thereby achieving that new content that may appear in the matching process will not appear again.

[0094] The determined regular expression is a regular expression corresponding to the non-empty matching content in the compound regular expression group.

[0095] For further information, see Figure 2 , Figure 2 This is a flowchart of a method for searching information in an electronic automation design file library provided in an embodiment of the present application. Figure 2 As shown, the user configures the file according to the YAML writing language to obtain an abstract syntax tree, reads the configured YAML according to the user's first information search request to determine the initialization regular expression group, merges the initialization regular expression group to obtain a composite regular expression group, obtains the target file from the electronic automation design file library, uses the composite regular expression group to traverse and match the target file, and detects whether the match is successful. If successful, the matching result is determined and saved, and then the initialization regular expression group is updated according to the matching result. If unsuccessful, the match is performed again.

[0096] The present application provides an information search method for an electronic automation design file library, the information search method comprising: performing DSL configuration definition on the content information and regular expression of each file in the electronic automation design file library based on the YAML writing language, generating an abstract syntax tree of the electronic automation design file library; traversing and reading the abstract syntax tree based on the first information search request of the target user, determining the target file corresponding to the first information search request in the abstract syntax tree and the first initialization regular expression group of the target file; merging the first initialization regular expression group to generate a composite regular expression group, matching the target file information based on the composite regular expression group, and if the match is successful, determining the information search result, and displaying the information search result to the target user.
