[0002] In chip design code, in order to facilitate text replacement of the code, a large number of macro texts are usually used to participate in design programming. The macro reference line includes macro references and non-macro internal identifiers, and the macro text content is various. The identifier specifically includes signals, parameters, models, functions, tasks and instances. In the macro text expansion process of the macro reference line, the non-macro internal identifier may be incorrect, and the existing electronic design automation (Electronic Design Automation, referred to as EDA) tool usually only supports the conventional expansion of the macro text in the chip design code file, and does not support the functions of syntax analysis, identifier identification and binding of the expanded text. Thus, the debugging requirement of the non-macro internal identifier of the expanded macro text cannot be met. Therefore, how to accurately and quickly realize the debugging function based on the expanded non-macro internal identifier becomes a technical problem to be solved. SUMMARY

[0006] Further, the step S2 includes: Step S21: sequentially obtaining identifiers in the macro reference line from a starting column to an ending column of the macro reference line to construct an identifier list, and sequentially obtaining macro references to construct a macro reference list; Step S22: setting a first pointer to point to a first identifier in the identifier list of the macro reference line, and setting a second pointer to point to a first macro reference in the macro reference list; Step S23: if a starting column number of the identifier currently pointed to by the first pointer is smaller than a starting column number of the macro reference currently pointed to by the second pointer, performing step S27, otherwise, performing step S24; Step S24: if an ending column number of the identifier currently pointed to by the first pointer is smaller than an ending column number of the macro reference currently pointed to by the second pointer, performing step S25, otherwise, performing step S26; Step S25: if the first pointer currently does not point to a last identifier in the identifier list of the macro reference line, updating the first pointer by 1, and returning to perform step S23, otherwise, ending step S2; Step S26: if the second pointer currently does not point to a last macro reference of the macro reference line, updating the second pointer by 1, and returning to perform step S23; In step S27, the positioning information of the identifier currently pointed by the first pointer is acquired, and the macro reference identifier currently pointed by the second pointer is determined as the macro reference identifier corresponding to the identifier currently pointed by the first pointer, and the execution returns to step S25.

Attached Figure Description

[0015] To more clearly illustrate the technical solutions in the embodiments of the present invention, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0016] Figure 1 This is a flowchart illustrating the processing of inline non-macro identifiers for macro references provided in an embodiment of the present invention. Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides a method for handling inline non-macro identifiers referenced in macros, such as... Figure 1 As shown, it includes: Step S1: Obtain the storage information corresponding to each macro reference in the macro reference line.

[0019] The storage information corresponding to the macro reference includes a macro reference identifier, a line number in the macro expanded text of the macro reference line, and a list of macro identifiers corresponding to the line number in the macro expanded text of the macro reference line. The list of macro identifiers includes at least one macro identifier location information. The macro identifier location information includes a binding object, the location information of the macro reference corresponding to the macro identifier in the chip design code original file, and the location information of the macro identifier in the macro expanded text of the macro reference line. The binding object is an object that can be identified and supports debugging operations.

[0020] It's important to note that the chip design code source file refers to the code file generated based on a hardware description language. Specific hardware description languages ​​can include Verilog, SystemVerilog, VHDL, etc. Macro identifiers refer to the identifiers contained within the macro expanded text. Macro identifiers can specifically be signals, parameters, models, functions, tasks, and instances, etc. It's understandable that macros with the same name can be used in different locations, corresponding to different macro references.

[0021] A macro reference identifier is a unique identifier that can identify a macro reference. Specifically, a macro virtual file can be created for each macro reference, and the macro reference identifier can be set as the macro virtual file identifier. The macro virtual file can include the macro virtual file identifier, the initial expanded text of the macro, the initial line number of the macro identifier, and the initial column number range of the macro identifier. The initial line number of the macro identifier is the line number of the macro identifier in the initial expanded text of the macro, and the initial column number range of the macro identifier is the column number range of the macro identifier in the initial expanded text of the macro.

[0022] A bound object refers to an object that can be identified and supports debugging operations. Debugging operations specifically include searching, annotation, tracing links, and definition jumps. Annotation operations can take the form of highlighting, selecting boxes, etc.

[0023] Step S2: Obtain the location information of non-macro identifiers in the macro expanded text of the macro reference line and the corresponding macro reference identifier to be added.

[0024] The non-macro identifier location information includes the binding object, the position information of the non-macro identifier in the original chip design code file, and the position information of the non-macro identifier in the macro expanded text of the macro reference line. The macro reference identifier to be added corresponding to the non-macro identifier whose starting column number is less than the starting column number of the first macro reference in the macro reference line is the first macro reference identifier. The macro reference identifier to be added corresponding to the non-macro identifier whose starting column number is greater than the ending column number of the (i-1)th macro reference and less than the starting column number of the i-th macro reference is the i-th macro reference identifier. The macro reference identifier to be added corresponding to the non-macro identifier whose starting column number is greater than the right starting column number of the i-th macro reference is the i-th macro reference identifier. i is any integer from 2 to i, and i is the total number of macro references in the macro reference line.

[0025] It should be noted that the macro reference identifier to be added refers to the macro reference identifier corresponding to the list of macro identifiers to which the non-macro identifier positioning information needs to be added. The correspondence between the non-macro identifier positioning information and the macro reference identifier to be added is determined based on the positional relationship between the non-macro identifier and the macro reference. Non-macro identifiers can specifically be signals, parameters, models, functions, tasks, and instances, etc.

[0026] Step S3: Add the non-macro identifier location information to the macro identifier list corresponding to the macro reference identifier to be added.

[0027] It should be noted that adding the location information of non-macro identifiers to the list of macro identifiers corresponding to the macro reference identifier to be added also adds the location information of non-macro identifiers to the storage information corresponding to the macro reference. This makes the storage information corresponding to the macro reference contain both macro identifier location information and non-macro identifier location information. Non-macro identifiers can also be used to implement debugging functions based on the storage information corresponding to the macro reference.

[0028] As one embodiment, the method further includes: Step S4: Based on the position of the non-macro identifier in the macro expanded text of the macro reference line, find the storage information corresponding to the macro reference in the macro reference line, and determine the binding object corresponding to the non-macro identifier.

[0029] It should be noted that since the storage information corresponding to the macro reference already stores the location information of the non-macro identifier, and the relationship between the location information of the non-macro identifier and the binding object is clear, the binding object corresponding to the non-macro identifier can be determined by the position of the non-macro identifier in the macro expansion text of the macro reference line.

[0030] Step S5: Perform debugging operations on non-macro identifiers in the macro expansion text of the macro reference line based on the binding object corresponding to the non-macro identifier.

[0031] It should be noted that, since the bound object is an object that can be recognized and supports debugging operations, once a non-macro identifier is bound to the corresponding bound object, debugging operations can be performed on the non-macro identifier in the macro expansion text of the macro reference line based on the bound object corresponding to the non-macro identifier.

[0032] It should be noted that in the prior art, the macro expansion text of the macro reference line is plain text information and cannot be used for debugging operations. In this embodiment of the invention, based on the position of the non-macro identifier in the macro expansion text of the macro reference line and the storage information corresponding to the macro reference, the binding object corresponding to the non-macro identifier can be accurately and quickly obtained. The non-macro identifier in the macro expansion text of the macro reference line is bound to the binding object, thereby enabling debugging operations such as annotation, searching, tracing link relationships, and definition jump.

[0033] As one embodiment, step S2 includes: Step S21: Starting from the first column of the macro reference row and ending from the last column, retrieve the identifiers in the macro reference row to construct an identifier list, and retrieve the macro references to construct a macro reference list.

[0034] Step S22: Set the first pointer to point to the first identifier in the identifier list of the macro reference line, and set the second pointer to point to the first macro reference in the macro reference list.

[0035] Step S23: If the starting column number of the identifier currently pointed to by the first pointer is less than the starting column number of the macro reference currently pointed to by the second pointer, then execute step S27; otherwise, execute step S24.

[0036] It should be noted that if the starting column number of the identifier currently pointed to by the first pointer is less than the starting column number of the macro reference currently pointed to by the second pointer, it means that all or part of the identifier currently pointed to by the first pointer is located to the left of the macro reference currently pointed to by the second pointer, and the identifier currently pointed to by the first pointer is a non-macro identifier.

[0037] Step S24: If the end column number of the identifier currently pointed to by the first pointer is less than the end column number of the macro reference currently pointed to by the second pointer, then execute step S25; otherwise, execute step S26.

[0038] It should be noted that if the starting column number of the identifier currently pointed to by the first pointer is greater than or equal to the starting column number of the macro reference currently pointed to by the second pointer, and the ending column number of the identifier currently pointed to by the first pointer is less than the ending column number of the macro reference currently pointed to by the second pointer, then the identifier currently pointed to by the first pointer is an identifier within the macro reference currently pointed to by the second pointer, and can be skipped directly.

[0039] Step S25: If the current first pointer does not point to the last identifier in the identifier list of the macro reference line, then update the first pointer by 1 and return to step S23; otherwise, end step S2.

[0040] Step S26: If the first pointer does not currently point to the last macro reference in the macro reference line, then update the second pointer by 1 and return to step S23.

[0041] Step S27: Obtain the location information of the identifier currently pointed to by the first pointer, and determine the macro reference identifier currently pointed to by the second pointer as the macro reference identifier to be added corresponding to the identifier currently pointed to by the first pointer, and return to execute step S25.

[0042] It should be noted that, through the processing of steps S21-S27, a corresponding macro reference identifier to be added is determined for each non-macro identifier in the macro reference row.

[0043] As one embodiment, in step S27, obtaining the location information of the identifier currently pointed to by the first pointer includes: Step S271: Set the binding object of the identifier currently pointed to by the first pointer.

[0044] Step S272: Obtain the line number and column number range of the identifier currently pointed to by the first pointer in the original chip design code file, and add them to the position information of the identifier currently pointed to by the first pointer in the original chip design code file.

[0045] Step S273: Obtain the row number and column number range of the identifier currently pointed to by the first pointer in the macro expanded text of the macro reference line, and add it to the position information of the identifier currently pointed to by the first pointer in the macro expanded text of the macro reference line.

[0046] As one embodiment, step S272 further includes: obtaining the code region identifier corresponding to the identifier currently pointed to by the first pointer in the original chip design code file, and adding it to the position information of the identifier currently pointed to by the first pointer in the original chip design code file.

[0047] It should be noted that the data structure of non-macro identifier location information and macro identifier location information is the same. That is, macro identifier location information is also included in the corresponding code region identifier in the chip design code source file.

[0048] As one embodiment, step S273 further includes: determining the macro reference identifier currently pointed to by the second pointer as the macro reference identifier corresponding to the identifier currently pointed to by the first pointer, and adding it to the position information of the identifier currently pointed to by the first pointer in the macro expansion text of the macro reference line. The chip design code source file can be divided into multiple code regions, and the storage information corresponding to macro references can be stored in separate code regions, which facilitates storage and subsequent retrieval, and further improves the processing efficiency of non-macro identifiers.

[0049] It should be noted that the data structure of non-macro identifier location information and macro identifier location information is the same. That is, macro identifier location information is also included in the corresponding macro reference identifier in the chip design code source file.

Furthermore, the order of the steps can be rearranged. A process can be terminated when its operation is complete, but it may also have additional steps not included in the figures. A process can correspond to a method, function, procedure, subroutine, subroutine, etc.

[0052] In this embodiment of the invention, storage information corresponding to each macro reference in the macro reference line is first created. The macro identifier positioning information is then added to the storage information corresponding to the macro reference. Then, based on the positional relationship between non-macro identifiers and macro references in the macro reference line, the non-macro identifier positioning information is added to the macro identifier list corresponding to the macro reference identifier. This ensures that each non-macro identifier also contains the binding object and position information in the storage information corresponding to each macro reference. This enables accurate and rapid binding of objects to non-macro identifiers after the macro reference line is expanded, and debugging functions are implemented based on the bound objects.
