Description

Error information processing method, apparatus, device, storage medium and program product

Technical Field

The present application relates to the field of electronic design automation, and in particular, to an error reporting information processing method, apparatus, device, storage medium, and program product.

Background

Electronic Design Automation (EDA) software refers to Design software that uses computer-aided Design (CAD) to complete the processes of functional Design, integration, verification, physical Design (including layout, wiring, layout, design rule check, etc.) of very large scale integrated circuit (VLSI) chips.

In order to record various error messages in the operation process of the system, for example: information such as crash, error or warning is generally recorded in the EDA software by using a system log, and if information such as crash, error or warning is detected during the running process of the program, the log system records key information such as the position of occurrence, the object of occurrence, the time of occurrence, the cause of the occurrence of the error information, and specifically, the log system is roughly divided into three types: application logs, system logs, and security logs, a log system typically comprising: the system comprises five modules of log collection, log transmission, log storage, log analysis and error report. Users can obtain the system running state through inquiring the log, and system operation and development personnel can also know the real-time information generated in the running system, the error in the checking and configuring process and the reason of the error through the log.

Existing EDA software uses logs to record error information encountered: after the chip design file and the related library file are read in and the system is started, the system verifies the content in the design file according to each detection item, and information such as errors, warnings and the like in verification is immediately recorded in a log file until the system is completely operated. However, existing EDA software is difficult to help a user find out a root cause of an error, and after that, the user needs to query a log file generated by a system to find a problem occurring in a design, for example, to browse each piece of information recorded in a log one by one according to a time sequence to perform information query, or to use Linux commands such as grep, awk, and wc to implement retrieval and statistics, so that efficiency is low, the user is difficult to find a problem point where an error-reporting object is more accurate through the log file, and cannot conveniently query target information, and such a method is still necessary for higher-requirement query, sorting, and statistics, particularly, more detailed information of a related object that needs to generate error information in an error troubleshooting process, and the like.

Therefore, the EDA software needs an error information processing method to help the chip designer to find the problem as early as possible, to provide the user with design error information to help find the problem as early as possible and to improve the chip design, reducing the time cost and economic cost due to the design deviation.

The error information processing method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through some embodiments and application scenarios thereof.

Referring to fig. 1, fig. 1 is a flowchart of an error message processing method according to an embodiment of the present application. As shown in fig. 1, the error information processing method may include the following steps:

step 101, creating a log file, and recording verification log information generated in the running process of the electronic design automation software into the log file, wherein each verification log information has a corresponding information identifier.

In specific implementation, the EDA software can verify the contents of the chip design file and the related library file during the operation process to obtain the verification log information. The verification log information may include information such as crashes, errors, warnings, etc. encountered in the verification. The verification log information may record the location where the above information (crash, error, warning, etc.) appears, the object of occurrence, the time of occurrence, the cause of the occurrence, and the like.

In the embodiment of the present application, each verification log Message has a corresponding Message ID (Msg ID).

and responding to the selection operation, and determining that a query request of a user for a first information identifier in the log file is received, wherein the first information identifier is an information identifier corresponding to the first content.

In specific implementation, a user may read the log file and select an interested content, that is, a first content, from the log file, where the first content may be a part or all of the content in the first verification log information, and the first verification log information is the verification log information corresponding to the first information identifier. In this way, the information identifier corresponding to the first content may be determined as the first information identifier, and the query request of the user for the first information identifier may be received.

As can be seen, in this embodiment, if a selection operation of the user on the first content in the log file is received, a query request of the user on the information identifier corresponding to the first content may be visually received. The first information identification is the information identification corresponding to the first content, and the first information identification is selected by a user in a self-defined mode after the user reads the log file.

In other embodiments, step 102 is embodied as: first information identification input by a user is received.

In this embodiment, if the first information identifier input by the user is received, a query request of the user for the first information identifier may be considered to be received. The first information identification is autonomously input by the user.

In the embodiment of the application, the user can self-define and query the information of the object related to the object according to the requirement, so that the user can fully exert subjective initiative to quickly locate the problem, and the user can conveniently and efficiently track and analyze the problem.

Step 103, in response to the query request, querying an object in the first verification log information corresponding to the first information identifier in the log file to obtain an object query result, where the object query result includes related information of the queried object, and the related information includes at least one of name information, attribute information, and connection object information.

For convenience of description, an object in the first authentication log information is hereinafter referred to as a first object.

After receiving the query request, a query operation on the first object may be performed to obtain at least one of name information, attribute information, and connection object information of the first object.

The following describes objects in the authentication log information.

In some embodiments, the object may include: an object of operation in a digital chip design. Further, the operation objects in the digital chip design may include, but are not limited to: a connection (net), a module (cell), a pin (pin), and a port (port).

In other embodiments, the object may include: objects of a unified low power format standard. Further, the objects of the unified power consumption format standard may include, but are not limited to, at least one of power domains (power domains), power lines (supply nets), connection relationships between power nodes, isolation Circuits (Isolation Circuits), level-shifting Circuits (level-shifting Circuits), and state-retention Circuits (state-retention Circuits).

The attribute information of the object is explained below.

In some embodiments, the attribute information may include, but is not limited to, at least one of: hierarchy (scope) information, netlist (owner) information, netlist instance (view) information. In other words, the attribute information of the object includes scope, owner, view, and the like information of the object. In this way, the relationship information of the object and other objects can be provided through the attribute information of the object, and the associated object of the first object can be determined.

The following describes connection target information of a target.

In some embodiments, the connection object information may include, but is not limited to, name information and attribute information of the connection object.

For convenience of description, the connection object of the first object is hereinafter referred to as a second object. In this way, the relationship information between the connection object of the object and other objects can be provided through the connection object information of the object, and the associated object of the second object can be determined.

In the embodiment of the application, a user can inquire the information of the first object, the information of the associated object of the first object and/or the information of the associated object of the second object through the first information identifier, so that the user can be helped to quickly find out a chip design problem and the positioning speed of the chip design problem is improved.

For ease of understanding, the examples are illustrated below: one of the original verification log information recorded in the log file of the electronic design automation software is as follows: 2022-10-19 (IsoUnmatched): PD2_ iso2_0_UPF _ISO:/test _ data/check/no _ drive, wherein the information is identified as IsoUnmatched, which indicates that the module (cell) of the isolation type has the problem of failure to match, and PD2_ iso2_0_UPF _ISOis the name information of the object of the cell.

In this embodiment, the verification log information is used as first verification log information, and the information identifier "isoumamated" in the verification log information is used as a first information identifier in this embodiment, and an object in the first verification log information is queried in response to the first information identifier.

Further, the error information processing device, upon receiving the first information identifier, is: after the query request corresponding to the information identifier isoumatched, the object in the first verification log information corresponding to the first information identifier that can be queried at least includes the following item: name information of the object, such as PD2_ iso2_0_UPF _ISO; attribute information of an object, such as PowerDomain (power domain) of PD2_ iso2_0_upf _iso; connection information of the object, for example: PD2_ iso2_0_upf _isoconnected net (connection line) and port (port). Thus, the user can quickly locate the Net with the problem in the verification log information and prompt possible reasons according to the information.

And 104, outputting the object query result.

In a specific implementation, the object query result may be written in at least one of a log file, a Comma-Separated Values (CSV) file, and a console for a user to obtain.

It should be noted that in the scenario where the object query result is written into the log file, the log file written by the object query result may be different from the log file in step 101, so that the user may directly query the related information of the first object by looking up the log file, thereby improving the information query efficiency.

In some embodiments, the step 104 of outputting the object query result may specifically include:

judging whether the inquired object belongs to an object which is interested by the user, if so, simultaneously taking the name information of the object, the attribute information or the connection object information as an output object inquiry result;

if not, the obtained name information of the object is used as an output object query result;

and after the user views the log file or the object query result reported by the electronic design automation software, the object interested by the user is selected according to the information prompt of the viewed log file or the viewed object query result.

According to the error information processing method, verification log information generated by EDA software in the running process and information identification corresponding to each verification log information are recorded in a log file, a user can inquire relevant information of an object in the first verification log information corresponding to the first information identification through the first information identification in the log file, and the relevant information comprises at least one item of name information, attribute information and connection object information. Therefore, the method can help a user to find the chip design problem as early as possible and improve the chip design, and reduce the time cost and the economic cost brought by the design deviation.

According to the error reporting information processing method, the query result of the object which is rich in information and can be operated is reported to the user, so that the user is effectively helped to accurately locate the chip design problem, the problem reason is convenient to analyze, the reading cost of the user for directly querying the log file content is reduced, the tool developer is convenient to quickly locate and diagnose the problem of the tool, repeated time-consuming long trial operation is avoided, and the query and problem analysis efficiency is improved; the object query result can supplement or replace only log output under the default condition of the system, the user can select and organize the content and format of the object by himself, the more directional and rich output information is beneficial to the user to find the source of errors quickly, the user-defined query scheme has flexible screening and tracing capacity for the data object, the size of log files can be greatly reduced, information with strong pertinence is provided, and the debugging efficiency can be improved to a great extent.

It should be noted that the embodiment of the present application is not limited to a specific implementation manner of querying the related information of the first object, and any implementation manner that can implement querying the related information of the first object may fall within the scope of the embodiment of the present application. Such as:

in some embodiments, the device may query the first object according to a predefined query rule to obtain the related information of the first object, and the query rule may be used to query the related information of each object.

In some embodiments, said querying, in response to the query request, an object in the first verification log information corresponding to the first information identifier is queried in the log file to obtain an object query result, where the querying may include:

responding to the query request, executing a first target function corresponding to the first information identification to obtain an object query result;

wherein the first objective function is used for querying the object in the first verification log information.

The target function can be registered by the user based on own requirements, namely the target function can be customized by the user. The present application does not limit the concrete expression of the objective function, and in an alternative implementation, the objective function may be a tool Command Language program (Tools Command Language program, also called "TCL Proc"), but is not limited thereto.

In this embodiment, the object query result may be obtained by executing a first target function corresponding to the first information identifier, and an execution result of the first target function is the object query result.

The first objective function may be obtained by receiving in advance, or obtained by registering in advance, which may be determined according to actual requirements, and this is not limited in this embodiment of the application. For the latter, in some embodiments, before the executing the first objective function in response to the query request and obtaining the object query result, the method further includes:

acquiring a first function script corresponding to the first information identifier;

registering the first function script through an extensible interface of the electronic design automation software according to the first information identifier to obtain a first target function;

and establishing a corresponding relation between the first objective function and the first information identifier.

In this embodiment, a user may browse each piece of verification log information recorded in the log file, and if a piece of verification log information is interested, the user may write a function script by using an information identifier corresponding to the verification log information to query related information of an object in the verification log information, thereby achieving an effect of root tracing.

In specific implementation, after a first function script corresponding to a first information identifier is obtained, the first function script may be registered through an expandable interface of EDA software by using the first information identifier to create and obtain the first objective function, and a corresponding relationship between the first objective function and the first information identifier is established.

Therefore, after receiving a query request of a user for the first information identifier, the first target function can be called to query the relevant information of the object in the first verification log information, and the information query efficiency is improved.

In the case where the objective function is a Tcl Proc function, the objective function may be obtained using a Tcl Command (Tcl Command) registration function script.

The Tcl command is a way for the electronic design automation software to provide a user with a control system, and the user can issue commands to the system via the Tcl language. The Tcl command may include at least one of:

use _ tcl _ proc: may be used to register the Tcl function according to message _ id;

set _ param: may be used to update configuration information;

get _ param: can be used to obtain configuration information;

check _ upf: may be used to issue an authentication command;

the issue _ message can be used for outputting information corresponding to the Msg _ ID;

set _ msg _ timing-message _ id abc 123-timing _ level LOG _ INFO: the error reporting method can be used for setting corresponding error reporting information as an error reporting grade given by a user according to the Msg _ ID and the error reporting severity grade given by the user;

get _ message _ help-message _ id abc123: can be used for inquiring the help information of the error message according to the Msg _ ID input by the user.

Such as the above, to the user. The electronic design automation software can perform corresponding operation according to the command, and relevant information in the system operation process is written into a log file or a configuration file.

In an optional implementation manner, the step of receiving a registration command from a user using the electronic design automation software, and registering or updating the first function script corresponding to the first information identifier may register the first function script using use _ Tcl _ proc in a Tcl command, so as to obtain the first objective function.

For ease of understanding, examples are illustrated below:

in this example, the first function script (tclprocforsmsgid) may be as follows:

proc TclProcForMsgId { msg_body portNf obj1 } {

if {[IsObjOfInterest $obj1] } {

issueMessage(msg_body)

issueMessage(“ Port info is as follows”, obj1->Name(), obj1->Parent()->Name())

} else {

issueMessage($msg_body, $id, $obj1->Name())

}

the registration is then performed using the use _ tcl _ proc command:

use_tcl_proc mssage_id TclProcForMsgId

the creation of the first objective function Tcl Proc is completed through the above operations, and the association between the first objective function Tcl Proc and the first information identifier Message _ ID is established.

Tcl prco is shown below:

Following TCL proc exist for portNf

proc TclProcForMsgId { msg_body portNf obj1 } {

if {[IsObjOfInterest $obj1] } {

issueMessage(msg_body)

} else {

issueMessage($msg_body, $id, $obj1->Name())

}

the results of the implementation of Tcl prco are shown below:

ERROR: 31-08-21 16:30 Serious error

ERROR 31-08-21 16. The Port info is as follows is description information about the result of the object query, 129 is name information of the object in the result of the object query, and parent _ name is name information of the connected object in the result of the object query.

In specific implementation, the first function script may be obtained in multiple ways, which is specifically described as follows:

in some embodiments, the obtaining the first information identifier corresponding to the first function script may include:

1) Under the condition that the first function script which is defined in advance exists in a configuration file of the electronic design automation software, the first function script in the configuration file is operated;

alternatively, the first and second liquid crystal display panels may be,

2) And receiving a first function script corresponding to the first information identifier which is registered or updated by a user by using a registration command in the electronic design automation software.

In 1), the first function foot is predefined in and obtained from a configuration file of the EDA software. In 2), the first function script is obtained by registering or updating a user by using a registration command of the EDA software, and in specific implementation, the user may register or update the first function script by using the registration command use _ tcl _ proc when the EDA software is started or after the EDA software finishes running.

By the method, the function script can be acquired in various ways, and the acquisition modes of the function script are enriched.

In some embodiments, said executing, in response to the query request, the first information identification corresponding to the first objective function to obtain an object query result may include:

responding to the query request, and checking whether a first target function corresponding to the first information identification exists;

under the condition that the first objective function exists, executing the first objective function to obtain an object query result;

the method further comprises the following steps:

under the condition that the first objective function does not exist, inquiring a first severity level and a first detailed degree corresponding to the first information identification;

inquiring information in the first verification log information in the log file according to the first severity level and the first detail degree to obtain an information inquiry result;

and outputting the information query result.

It is to be understood that there is not necessarily a corresponding objective function for each information identifier in the log file. Therefore, in this embodiment, when an inquiry request for a certain information identifier in a log file is received, it may be checked first whether an objective function corresponding to the information identifier exists, and based on the check result, a corresponding inquiry operation is performed.

For ease of understanding, reference is made to fig. 2. And under the condition that the corresponding target function exists, calling the target function, and inquiring the relevant information of the object by using the target function.

Under the condition that the corresponding target function does not exist, the corresponding severity level and the detail degree can be inquired, then, the spdlog function can be called, the information in the corresponding verification log information can be inquired from the log file according to the corresponding severity level and the detail degree, the information inquiry result is obtained, and the information inquiry result is output. The information query result may include at least one of: help information; and verifying the printing information of the log information, such as the upper limit of the number of printing and the like.

By the method, after the query request of a certain information identifier is received, the corresponding query operation can be executed based on whether the check result of the target function corresponding to the information identifier exists, so that the flexibility of information query can be improved.

In some embodiments, before recording verification log information generated by the electronic design automation software during the operation process into the log file, the method further comprises:

acquiring a JSON configuration file, wherein the JSON configuration file comprises information blocks;

the recording of the verification log information generated by the electronic design automation software in the running process into the log file comprises the following steps:

recording verification log information generated by electronic design automation software in the running process into the log file according to a format specified by the information block;

wherein the information block includes:

a format string field including a first field and a placeholder, wherein the first field is used for filling in the verification log information or the description information of the object query result, and the placeholder is used for placeholdering the object in the verification log information;

and the target function character string is used for filling the function script.

Further, the information block corresponding to each piece of information may further include at least one of: help (help) field; an internal (internal) field; a maximum occurrence limit (maxOccurrenceLimit) field; a severity field.

The above-described fields are explained below.

formatted _ string: the information not only comprises the verification log information or the description information of the object query result, but also occupies the object in the verification log information. And the filling of the object is delayed to the system operation, so that the decoupling between the verification log information and the object and more flexible information combination are realized. In addition, the formatted _ string also unifies the format of the error information, and the reading cost of the user is reduced. The description information of the object query result may represent a description or interpretation of the object query result by the user.

Help: indicating the help information corresponding to each message _ id.

Internal: information indicating printing inside the system is not displayed to the user.

maxOccurrenceLimit: indicating an upper limit of the number of times a piece of authentication log information is printed in the system.

message _ id: an information identifier unique to each piece of authentication log information is indicated.

Setting: indicating the level of error information. The following six grades are mainly classified:

LOG _ CRITICAL: the system verifies the critical error information and cannot be downgraded.

LOG _ ERROR: error information verified by the system, but error level can be reduced by the user to LOG WARNING.

LOG _ WARNING: the system verifies the warning message.

LOG _ INFO: the information that the system needs to output in operation.

LOG _ DEBUG: and when the system is set to the debug mode, outputting corresponding information needing debug.

LOG _ ALWAYS is the information which needs to be output by default in the running of the system and is used for testing.

The initialized configuration file may be as follows:

{

"formattedString":"Net/Port is not present in the current scope : %",

"help":"This message is to be used when Net/Port is not present in the current scope",

"internal":"NO",

"maxOccurrenceLimit":"100",

"messageId":"NetUnkown",

"severity":"LOG_ERROR",

"tclProc":""

}

in the above example, the description information of the object query result identified by the information about netunsewn is Net/Port is not present in the current scope, and the placeholder of the object query result is expressed in%.

In an alternative implementation, the configuration file may be a JSON configuration file. The JSON configuration file can be used for storing the verification log information in a structured mode, is simple and easy to read and write, enables the analysis and the query of the verification log information to be convenient and efficient, and can be directly interacted with the development of a server end system. The JSON and C + + (business processing end) interactive tool can be nhlomann, and the tool has the advantages of high reliability, high interactive speed, source opening, sustainable maintenance and the like.

In some embodiments, the method may further comprise:

and receiving the first function script filled in the target function character string by the user.

In this way, a pre-definition of the first function script in the configuration file of the EDA software can be achieved.

In some embodiments, after the receiving the JSON configuration file, the method may further comprise:

creating a comma separated value cvs file according to the JSON configuration file;

displaying a graphical user interface according to the cvs file, wherein the graphical user interface comprises a first sub-area and a second sub-area, the first sub-area comprises at least one row, and each row is used for displaying the following information corresponding to one piece of verification log information in the cvs file: severity level, information identification, object query result, absolute path and row number of the object query result;

receiving a first input of a user to an ith row in the at least one row, wherein i is a positive integer;

in response to the first input, highlighting the ith row and displaying information of the ith row in the second sub-region;

receiving a second input of an object query result of a jth line in the at least one line by a user, wherein j is a positive integer;

in response to the second input, displaying the object query result of the jth row.

In this example, the csv file may be used to provide an efficient and fast information query file for a Graphical User Interface (GUI). The GUI directly captures information display from the csv file, provides a display window for verifying log information for a user, and provides multiple convenient operation modes.

In the GUI of this embodiment, the first column of the first sub-area is the version of the information, the second column is the Message ID of the information, the third column is the object query result (Message), and the fourth column is the absolute path (Source/relationship) and the line number of the object query result.
