The technical solutions shown in the present application will be described in detail below through specific examples. The following description of the embodiments is not intended to limit the priority of the embodiments.

Referring to fig. 1, fig. 1 is a flowchart of a standard cell library verification method according to an embodiment of the present application. The specific flow of the standard cell library verification method can be as follows:

101. and obtaining a standard cell library to be verified and a reference standard cell library.

The standard cell library is a basic roadbed cell set, and contains standard cells with rich types. The number of standard cells in a standard cell library typically varies from hundreds to thousands. Standard cells are the basis for electronic automation design of integrated circuits, particularly very large scale integrated circuits (Very Large Scale Integration, VLSI) automation design. The design of each standard cell in a standard cell library needs to meet a unified design rule so as to facilitate the subsequent splicing of rule cells and the construction of an integrated circuit.

It can be understood that the standard cell library to be verified is a newly developed standard cell library, and the reference standard cell library is a standard cell library meeting unified design rules.

102. And matching the standard cell library to be verified with the reference standard cell library to obtain a plurality of comparison groups.

In some embodiments, after the "computer library" program is started, the standard cell library to be verified and the reference standard cell library may be parsed. Specifically, the standard unit library to be verified and the reference standard unit library can be respectively analyzed to obtain a plurality of standard units to be verified and a plurality of reference standard units; and matching the standard units to be verified with the reference standard units to obtain a plurality of comparison groups.

It is understood that when a plurality of standard cells to be verified and a plurality of reference standard cells are matched, standard cells having correspondence may be formed into a group to be compared. However, in the actual application process, standard cells that are not present in the reference standard cell library may be present in the standard cell library to be verified, and standard cells that are not present in the standard cell library to be verified may be present in the reference standard cell library. Therefore, in some embodiments, the several standard cells to be verified and the several reference standard cells may be aligned and matched according to a matching algorithm, so as to obtain several comparison groups.

In some embodiments, standard cells to be verified and/or reference standard cells that do not have correspondence may be combined with empty cells to align a number of standard cells to be verified and a number of reference standard cells, generating a number of comparison sets. It should be noted that the to-be-compared group is a first sub-to-be-compared group, a second sub-to-be-compared group or a third sub-to-be-compared group.

Specifically, a standard unit to be verified and a reference standard unit with corresponding relations can be determined according to a matching algorithm, and the standard unit to be verified and the reference standard unit with corresponding relations are used as a first sub-comparison group; forming a second sub-comparison group by the standard unit to be verified and the empty unit which have no corresponding relation; and forming a third sub-comparison group by the reference standard units and the empty units which have no corresponding relation.

It should be noted that the empty cells do not have any information, and are only used for combining with the standard cells to be verified and/or the reference standard cells and the empty cells, so that no influence is generated on the standard cell library to be verified and/or the reference standard cell library.

103. And carrying out comparison verification on the group to be compared by adopting a corresponding comparison algorithm to generate a comparison result.

In some embodiments, when the to-be-compared group is the second sub-to-be-compared group or the third sub-to-be-compared group, the to-be-verified standard unit or the reference standard unit in the to-be-compared group is used as the comparison result.

It can be understood that the standard cell to be verified or the reference standard cell at this time is newly added cell information or missing cell information of the standard cell library to be verified. Since the object of the comparison is a null unit, the object is the comparison result.

In some embodiments, when the to-be-compared group is the first sub-to-be-compared group, the type of the to-be-compared group is obtained, and a corresponding comparison algorithm is called according to the type of the to-be-compared group to perform comparison verification on the to-be-compared group, so as to generate a comparison result.

In some embodiments, the comparison may be performed by extracting corresponding feature information according to types of the standard cell to be verified and the reference standard cell in the group to be compared.

In some embodiments, the characteristic information may be specific parameter information of the standard cell to be verified and the reference standard cell. Such as delay, transition, constraint of a nonlinear delay model (Non Linear Delay Model, NLDM); the ccs_delay and ccs_trans of the Composite Current Source (CCS) model. For example, when the standard unit to be verified and the reference standard unit are nonlinear delay models, parameter information such as delay, transition, constraint of the standard unit to be verified and the reference standard unit can be extracted respectively, and then one-to-one comparison is performed, so that a comparison result is generated.

Specifically, feature extraction can be performed on a standard unit to be verified and a reference standard unit in a group to be compared according to types to obtain first feature information and second feature information; determining a comparison algorithm according to the first characteristic information and the second characteristic information; and comparing and verifying the first characteristic information and the second characteristic information by adopting a comparison algorithm to generate a comparison result.

It can be appreciated that the comparison algorithms employed for the comparison of the different characteristic information are different. For example, when the characteristic information is noise, the adopted comparison algorithm is a noise comparison algorithm; when the characteristic information is time delay, the adopted comparison algorithm is a time delay comparison algorithm.

104. And (5) classifying and storing the comparison result.

Specifically, the classification of the comparison result can be determined; and storing the comparison result into the corresponding summary file according to the classification.

In some embodiments, after the comparison is made, the comparison is stored in a default folder (compactison). The preset folder is provided with a plurality of preset files. The summary log file is a summary of comparison results of the standard cell library to be verified; the attr_summary log file is used for summarizing information such as deletion, addition or mismatching of attrites in a standard unit library to be verified; the group_summary log file is used for summarizing missing and added information of groups in a standard unit library to be verified; * The csv or log file (refers to the supported data types such as delay. Csv or delay. Log) is to summarize the comparison result of the supported data types.

In summary, the standard cell library verification method provided by the embodiment of the application includes obtaining a standard cell library to be verified and a reference standard cell library; matching the standard cell library to be verified with the reference standard cell library to obtain a plurality of comparison groups; performing comparison verification on the group to be compared by adopting a corresponding comparison algorithm to generate a comparison result; and (5) classifying and storing the comparison result. The scheme can automatically verify the standard cell library to be verified without manual participation, so that the verification efficiency of the standard cell library is greatly improved, and the time cost is greatly saved. And moreover, a reasonable comparison algorithm can be determined according to the data type of the standard unit, so that the quality verification effect is more reliable than that of the traditional quality verification.

In order to facilitate better implementation of the standard cell library verification method provided by the embodiment of the application, the embodiment of the application also provides a standard cell library verification device. Where the meaning of nouns is the same as in the standard cell library verification method described above, specific implementation details may be referred to in the description of the method embodiments.
