Description

Target object positioning method and device, electronic equipment and storage medium

Technical Field

The present application relates to positioning technologies, and in particular, to a target object positioning method and apparatus, an electronic device, and a storage medium.

Background

With the rapid development of positioning technology, positioning information by using a positioning mode is a hot problem in current research. Especially in the field of Electronic Design Automation (EDA) of integrated circuits, how to realize the positioning of target objects in an integrated circuit database (e.g. each view in each cell and/or corresponding elements in each view) is a major issue of current research in the field of EDA of integrated circuits.

Currently, the positioning of target objects in an integrated circuit database generally refers to specifying a target unit where a pair of target objects to be matched are located, and when positioning the target objects, one or more target objects are selected from one target unit and positioned in another target unit. Specifically, taking a target unit as each view in the integrated circuit database, taking a target object as each element in each view as an example, the manner adopted for positioning the corresponding element in each view is as follows: a pair of views to be matched, e.g., view a and view B, is specified, and when positioning corresponding elements in both views is performed, one or more elements are selected in one of the views (view a) and positioned to an associated one or more elements in the other view (view B).

For example, when the element corresponding to the positioning in each view is positioned, the view to be matched must be specified first, and when the element corresponding to the positioning in each view is positioned, the view to be matched can only be specified first, and when the element corresponding to the positioning in each view is positioned, the positioning in each view can only be realized in one-to-one manner, for example, when the view a is specified to be switched to the view B, the view a can only be switched to the view B, or the view B is switched to the view a, and when the view a is to be switched to the view C, the previously specified setting needs to be modified, which is tedious in operation process, slow in positioning, and affects user experience.

Detailed Description

In order to make the technical solutions of the present application better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are intended to be illustrative only and are not intended to be limiting. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.

It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples consistent with certain aspects of the present application, as detailed in the appended claims.

In the technical solution of the embodiment of the present application, the technical solution of the embodiment of the present application is mainly applicable to the field of integrated circuits. The following description will be given taking the integrated circuit field as an example.

For convenience of understanding of the technical solutions of the embodiments of the present application, a brief description will be given to the corresponding background technologies of the embodiments of the present application.

The design of an integrated circuit is typically implemented using EDAs, and a copy of the integrated circuit design data may be referred to as an integrated circuit database, which in one case may include a circuit diagram library, a layout library, an image library, a label diagram library, etc., wherein the circuit diagram, layout, image are of the type or attribute of the library. The data in each database is stored in the form of units. Each cell may contain one or more views. When a view is included, typically the attributes of the view are consistent with the attributes of the database. For example, cells in the circuit diagram library have only a circuit diagram view, and cells in the layout library have only a layout view.

In another case, there is a form of database that includes cells within the database, with multiple views below the cells, such as a cell AND2, that includes: circuit diagram views, symbolic diagram views, layout views, hardware description language verilog views, behavior behavioral views, and the like. Each view contains a large number of integrated circuit elements, and different views have a certain incidence relation, so that the internal integrated circuit elements have a certain corresponding relation, for example, a label view and a layout are obtained based on the same chip image, a circuit diagram is obtained by converting the label view/the layout, and the like. Thus, in actual analysis, the engineer needs to locate between different target units (e.g., cells and/or views in a database) in order to perform comprehensive analysis.

Taking the target unit as a view and the target object as an integrated circuit element as an example, when positioning the integrated circuit element between different views is implemented, a pair of views to be matched, such as view a and view B, needs to be specified, and when positioning corresponding elements in the two views, one or more elements are selected in one view (view a) and are positioned to associated one or more elements in the other view (view B). The above manner of positioning the corresponding element in each view must specify the view to be matched first, and during positioning, only one-to-one positioning can be implemented, for example, if the view a is specified to be switched to the view B, only the view a can be switched to the view B, or the view B can be switched to the view a, if the view a is to be switched to the view C, the setting specified at the previous time needs to be modified, the operation process is cumbersome, positioning is slow, and user experience is affected.

In order to solve the above problem, an embodiment of the present application provides a target object positioning method to achieve positioning of each target object in a target unit.

Referring to fig. 1, a target object positioning method provided in the embodiment of the present application may specifically include the following steps:

and S110, responding to the selection operation of the target object in the target unit by the user, and determining the target object.

The target unit may be a cell in an integrated circuit database.

The target object may be an object to be located, the target object being in a target unit.

When the target object in the target unit is to be located, the user is required to first perform an operation of selecting the target object in the target unit, for example, the user may input the name of the target object to be located at the client, or the user may open the integrated circuit database at the client, select the target unit in the integrated circuit database, and then select the target object in the target unit. The server (integrated circuit database internal server) determines the target object to be located in response to the above-described user's selection operation of the target object in the target unit.

In one example, the target unit is an upper level cell of the target object.

Specifically, in one example, where the target object is a cell in a database, the target unit is the database;

in another example, where the target object is an integrated circuit element, the target unit is the view in which the integrated circuit element is located.

In one example, the views may be at least, but are not limited to, circuit diagrams, behavioral views, layouts, annotation views, hardware description language views, waveform views, and symbolic diagrams.

Wherein, the circuit diagram is as follows: also called schema view, the device extracted from the netlist has a circuit view of the connection relation.

Behavioral view (bsModule view): also called Behavioral view, is a visual circuit diagram of the behavior level statement transformation in verilog view.

Layout: also known as the Layout view.

Labeling the view: also known as an Annotation view;

hardware description language views: also known as verilog views.

And (3) waveform view: waveform view of circuit simulation.

Symbol diagram: also called Symbol view, which extracts from the circuit diagram a Symbol view expressing the function of the circuit.

The above-described views are all views of an integrated circuit as found in the prior art and are not described here in excess.

And S120, searching index information corresponding to the target object in a database index, wherein the database index is constructed by linking databases corresponding to the integrated circuit.

The database index may be an index library created from databases corresponding to the integrated circuit. Specifically, the databases corresponding to the integrated circuits may be linked to construct the database index.

In one example, the database index is actually an index established for a plurality of databases in one piece of integrated circuit design data, and may include index information of all databases in the design data, or may include index information of only at least two databases in the design data.

The index information corresponding to the target object may be information for searching for the target object corresponding to the target object, and specifically may be a name of the target object or the like.

After the target object is obtained, the database index may be searched for index information corresponding to the target object, specifically, the target object may be searched for in the database index, for example, a name of the target object may be input into the database index.

In the embodiment of the application, the database index can be constructed in advance, so that the integrated circuit database can be linked, when the target object is positioned, paired target units do not need to be selected in advance, and two target units for cross positioning do not need to be arranged repeatedly, so that the effect of cross positioning of the target object in multiple databases can be realized quickly in the following process.

S130, displaying a search result list corresponding to the target object, wherein the search result list comprises at least one search result, and each search result comprises: information of the target object and information of the target unit.

The search result list may be search results corresponding to the target object after searching the target object in the database index, and the search results are presented in a list form. Specifically, the search result list may include at least one search result, and each search result includes: the target object information and the target unit information.

In one example, the target object information may be not limited to include: the name of the target object and the belonging information of the target object.

In one example, the target unit information may be information of a target unit.

In one example, the attribution information of the target object may be attribution information of the target object.

In one example, when the target object is an integrated circuit element in a view, the information of the target object may be a type of the integrated circuit element, for example, the type of the integrated circuit element may be, but is not limited to, an instance, a net, a port, a text label, a hardware description statement, a signal waveform, and a symbolic diagram label. I.e., whether the integrated circuit element is an instance, or a net, or a port, etc.

That is, in the case that the target object is an integrated circuit element and the target unit is the view of the integrated circuit element, each search result includes: name of the integrated circuit element, attribute information of the integrated circuit element, and a view of where the integrated circuit element is located. Here, the attribute information of the integrated circuit element is the type of the integrated circuit element.

In another example, when the target object is a cell in the integrated circuit database, the information of the target object may be the database where the cell is located. Such as but not limited to standard digital cell libraries, version databases, netlist databases, top-level design databases, and the like.

That is, in the case where the target object is a cell in the database and the target unit is the database, the target object information included in each search result may be, but is not limited to, the name of the cell and the view under the cell, and the target unit information may be the database in which the cell is located.

After searching the target object in the database index, a search result list corresponding to the target object may be obtained, and the search result list may have each search result corresponding to the target object. And after the search result list corresponding to the target object is obtained, displaying the search result list so that a subsequent user can select the search result in the search result list, namely selecting the target search result so as to display result information corresponding to the target search result, thereby realizing the cross positioning of the target object in the database.

S140, responding to the selection operation of the target search result in the search result list, and displaying result information corresponding to the target search result, wherein the result information comprises: and the target object is in the view corresponding to the target search result and/or the target object.

The target search result may be any one of the search results in the search result list determined by the user performing the selection operation in the search result list. Specifically, the user clicks a certain search result or certain search results in the search result list at the client, and the certain search result or certain search results clicked by the user are the target search results.

The result information may be display result information corresponding to the target search result obtained in response to the user's selection operation on the target search result. Specifically, the view of the target object corresponding to the target search result and/or the target object may be used.

In one example, when the target object is a unit, the result information may be a view of the target object corresponding to the target search result, for example, when the target object is a unit, after clicking the target search result, the views corresponding to the unit may be displayed.

In another example, when the target object is an integrated circuit element, the result information may be the target object in addition to the view of the target object corresponding to the target search result. More specific result information may be a view of the target object corresponding to the target search result and/or the target object. That is, when the target object is an integrated circuit element, clicking the target search result can display the view in which the integrated circuit element is located and/or the integrated circuit element in the view.

Therefore, the result information corresponding to the target search result can be displayed by responding to the selection operation of the target search result in the search result list, namely the result information corresponding to the target search result can be obtained by the simple selection operation of the target search result in the search result list by the user.

According to the technical scheme of the embodiment of the application, the target object is determined by responding to the selection operation of the target object in the target unit by the user, the index information corresponding to the target object is searched in the pre-constructed database index, the search result list corresponding to the target object is obtained and displayed, and the result information corresponding to the target search result is displayed by responding to the selection operation of the target search result in the search result list. Therefore, the database indexes constructed in advance are used for linking the databases of the integrated circuits, so that the cross positioning of the target objects in the databases can be realized, the search results of the target objects can be completely displayed in a list form without repeatedly setting two target units for cross positioning, a user can select the target search results in the search result list according to the requirement and directly position the result information corresponding to the target search results, the operation is simple and convenient, the user experience is improved, and the cross positioning efficiency of the databases of the integrated circuits is also improved.

In one example, to achieve cross-location of target objects in multiple databases, it is most important to construct a database index in advance, the database index being constructed based on each database of the integrated circuit. Only if a database index is constructed in advance, when a target object is positioned, a matched target unit does not need to be set repeatedly in advance, because all databases of the integrated circuit are linked, namely all databases of the integrated circuit are correlated and are equivalent to a large database (index database), when the target object is positioned, the target object can be searched in the index database, all search results corresponding to the target object can be directly obtained, all the search results are presented in a list form, and when a user selects one or more search results (target search results) in a search result list, result information corresponding to the target search results can be directly jumped to.

Based on the above analysis, it can be seen that the core of the embodiment of the present application is to construct a database index, and as another implementation manner of the present application, in order to simply and conveniently implement cross location of a target object in multiple databases, the embodiment of the present application further provides another implementation manner of a target object location method, which may specifically be a construction manner of a database index, and specifically, refer to the following embodiments.

Referring to fig. 2, another implementation manner of the target object positioning method provided in the embodiment of the present application may specifically include the following steps:

s210, acquiring at least one database corresponding to the integrated circuit.

Before locating the target object, the databases of the integrated circuit are linked first. Before linking databases of an integrated circuit, at least one database corresponding to the integrated circuit needs to be acquired. Such as but not limited to standard digital cell libraries, version databases, netlist databases, top-level design databases, and the like.

S220, establishing a link relation for each database based on each integrated circuit element in each database to obtain a database index.

After the databases corresponding to the integrated circuits are obtained, the databases may be linked based on the integrated circuit elements in the databases, specifically, a link relationship may be established between the databases based on the same integrated circuit element in the databases, so as to obtain a database index.

Thus, based on the integrated circuit elements in the databases corresponding to the obtained integrated circuit, the database index is obtained by establishing a link relation for each database, which is equivalent to constructing a large database (index database) for each database corresponding to the integrated circuit, so that when a target object is positioned, the target object can be searched in the index database, and then each search result corresponding to the target object can be directly obtained without repeatedly setting a target unit corresponding to the matched target object in advance, the efficiency of cross positioning of the integrated circuit database is improved, the operation time cost of a user is saved, and the user experience is improved.

And S230, responding to the selection operation of the target object in the target unit by the user, and determining the target object.

And S240, searching the index information corresponding to the target object in the database index.

S250, displaying a search result list corresponding to the target object, where the search result list includes at least one search result, and each search result includes: information of the target object and information of the target unit.

And S260, responding to the selection operation of the target search result in the search result list, and displaying result information corresponding to the target search result.

Steps S230 to S260 in the embodiment of the present application are the same as steps S110 to S140 in the embodiment described above, and for the sake of brevity, are not described in detail here.

In the embodiment of the application, the link relation of the databases is established based on the acquired integrated circuit elements in the databases corresponding to the integrated circuits to obtain the database index, which is equivalent to constructing a large database (index database) for the databases corresponding to the integrated circuits, so that when a target object is positioned, the target object can be searched in the index database, and then each search result corresponding to the target object can be directly obtained without repeatedly setting a target unit corresponding to the matched target object in advance, thereby improving the efficiency of cross positioning of the integrated circuit databases, saving the time cost of user operation, and improving the user experience.

The above embodiment introduces a way of constructing a database index, and specifically describes how to establish a link relationship between databases based on each integrated circuit element in each database to obtain a database index. The embodiment of the present application further provides another implementable manner of the target object positioning method, which may specifically be a detailed construction process of a database index, and specifically refer to the following embodiments.

Based on each integrated circuit element in each database, establishing a link relationship for each database to obtain a database index, which may specifically include the following steps:

s2201, acquiring fields of all integrated circuit elements in all databases.

After each database corresponding to the integrated circuit is obtained, the fields corresponding to each integrated circuit element in each database can be obtained.

S2202, based on the fields, establishing a link relation of each database.

After the fields corresponding to the integrated circuit elements are obtained, a link relationship can be established for each database according to the fields, specifically, the link relationship of each database can be established by managing the databases with the same fields.

Therefore, the linking relation among the databases can be directly established through the fields of the integrated circuit elements in the data to obtain the database index, so that the integrated circuit elements in the database index have the corresponding relation, and the integrated circuit elements can be conveniently and subsequently positioned in a cross mode.

In the above embodiment, a way of quickly, simply and conveniently implementing cross-location of a target object based on a pre-constructed database index is introduced. In another embodiment, a user may modify data (e.g., cells, views, and integrated circuit elements) in each database corresponding to the integrated circuit, such that corresponding update of the database index constructed based on each database corresponding to the integrated circuit is required, so that cross-positioning of the target object based on the database index can be correctly achieved to obtain the correct target object.

In an example, in order to implement correct cross positioning of a target object based on a database index and obtain a correct target object, as another implementation manner of the present application, the present application may further provide another implementation manner of a target object positioning method, which may be specifically referred to in the following embodiments.

Referring to fig. 3, an implementation manner of another target object positioning method provided in the embodiment of the present application may specifically include the following steps:

s310, at least one database corresponding to the integrated circuit is obtained.

S320, establishing a link relation for each database based on each integrated circuit element in each database to obtain a database index.

Steps S310 to S320 in the embodiment of the present application are the same as steps S210 to S220 in the embodiment described above, and for the sake of brevity, are not described in detail here.

S330, when the update instruction of the database index is detected, updating the database index based on the update instruction.

The update instruction may be an instruction to update the above-obtained full data index. The specific update indication may be generated manually or automatically, and the generation process of the specific update indication is described in detail in the following embodiments.

When an update instruction of the database index is detected after the database index is obtained, for example, when an instruction to update the database index is received, the database index may be updated based on the update instruction.

Therefore, when data (such as units, views and integrated circuit elements) in each database corresponding to the integrated circuit are modified, database indexes constructed based on each database corresponding to the integrated circuit can be correspondingly updated, so that cross positioning of target objects can be correctly realized based on the database indexes, and correct target objects can be obtained.

And S340, responding to the selection operation of the target object in the target unit by the user, and determining the target object.

And S350, searching the index information corresponding to the target object in the database index.

S360, displaying a search result list corresponding to the target object, wherein the search result list comprises at least one search result, and each search result comprises: information of the target object and information of the target unit.

And S370, responding to the selection operation of the target search result in the search result list, and displaying result information corresponding to the target search result.

If the constructed database index is updated, steps S340 to S370 in the embodiment of the present application are all implemented based on the updated database index, and the specific implementation process is the same as that of steps S230 to S260, and for the sake of brevity, will not be described in detail here.

According to the technical scheme of the embodiment of the application, after the database index is constructed, if the data in each database corresponding to the integrated circuit is modified, the database index constructed based on each database corresponding to the integrated circuit can be correspondingly updated under the condition that the update indication of the database index is detected, so that the cross positioning of the target object can be correctly realized based on the database index, and the correct target object is obtained.

In the above embodiment, if the data in each database corresponding to the integrated circuit is modified, when the update instruction of the database index is detected, the database index constructed based on each database corresponding to the integrated circuit may be updated correspondingly, so that the cross-location of the target object based on the database index may be correctly realized.

Referring to fig. 4, a schematic diagram of a principle for updating a database index according to the present application is shown, in which a database corresponding to an integrated circuit is first opened, and then a database index is constructed, that is, information of a plurality of databases in the database is stored in the index, and only after the database index is created, the multi-database cross-location can be performed. All references to a specified target object are searched in the database index, and the search results are displayed as a list for selection. If the database index needs to be updated when the database is modified, the database index can be updated manually after modification, and the database index can also be updated automatically at set time.

The specific update indication for the database index may be generated manually or automatically, that is, the update for the database index may be manually updated or automatically updated. These two updating modes will be described in detail below.

(1) And (4) manually updating.

And under the condition that a trigger operation for reconstructing the database index is received, determining that an update instruction of the database index is detected, and updating the database index based on the update instruction.

The trigger operation to reconstruct the database index may be: after the user modifies the data in the database at the user end, the user performs an operation of reconstructing the database index, specifically, for example, the user clicks a button of "reconstructing the database index" at the user end.

When a trigger operation for reconstructing the database index is received, it may be determined that an update indication of the database index is detected, and the database index may be updated based on the update indication.

By means of manually updating the database index, the condition that the user does not want to update the database index can be avoided, the requirement of the user is met to the maximum limit, and the condition that the database index is updated by mistake can be avoided.

(2) And (4) automatic updating.

The preset time may be a preset time, for example, a week, a month, or the like, and the selection of the specific preset time may be set according to the user's requirement, which is not limited herein.

The user can preset a timing time, and the updating indication can be automatically generated at intervals of the preset timing time.

After the preset time is set by the user, when the preset time is reached, for example, the preset time may be a preset time from the time of building the database index or from the time of updating the database index last time, for example, a month is reached, an update instruction may be automatically generated, and the database index may be updated based on the update instruction.

By utilizing the mode of automatically updating the database index, the database index can be updated without manual operation of a user, the time of the user is saved, the user experience is improved, and the problem that the wrong result information corresponding to the target object is obtained when the database index is used next time under the condition that the user does not manually update the database index is avoided, or the user is required to update the database index before using the database index, the time is wasted, and the efficiency of cross positioning of the target object is delayed is solved.

It should be noted that, in the two ways of updating the database index, which updating way is specifically selected to update the database index may be selected according to the user requirement, and is not limited herein. Of course, the two updating modes can be selected simultaneously, and the method is not limited herein.

The manner in which the database index is updated in the present application may be described in a specific scenario below.

Specifically, a desCy signal (specifically, as shown in line 368 in fig. 5) may be added to the Verilog view of the oc8051_ alu _ test unit, and assigned in an always statement (specifically, as shown in line 369 in fig. 5), where the portion enclosed by the block in fig. 5 is a modified portion.

After updating the database index in the above manner, and after searching the line network desCy by using the updated database index, the obtained search result list may be as shown in fig. 6, where two lines framed by the square frame in fig. 6 are increased search results. In particular, the first row boxed in FIG. 6 corresponds to the added Port desCy at line 368 in FIG. 5, and the second row boxed in FIG. 6 corresponds to the added assign statement for the assign signal at line 369 in FIG. 5.

According to the technical scheme of the embodiment of the application, two ways of updating the database index are provided, and the correct database index is obtained through the two ways of updating the database index respectively, so that the correct database index can be used for realizing the cross positioning of the target object in the following process, and the correct cross positioning of the target object is realized.

In the description of the above embodiments, the target object may be two cases, one is an integrated circuit element and one is a cell in a database. For the two cases, the search result lists obtained by searching in the database index are different, and the finally obtained target search results are also different. Therefore, for these two cases, the two cases will be described below by way of example.

The following describes in detail the case where the target object is an integrated circuit element and the target unit is a view of the integrated circuit element.

For the convenience of understanding the embodiments of the present application, first, the principle of positioning the target object in the case that the target object is an integrated circuit element and the target unit is a view of the integrated circuit element will be described.

Referring to fig. 7, a certain view in a certain database of the integrated circuit is selected, a certain integrated circuit element in the view is selected for positioning, the integrated circuit element is searched in the created or updated database index, the search result is displayed in a list form, a user can select the integrated circuit element by himself according to the information in the list, and the user can automatically jump to the positioning view after selection to display the corresponding integrated circuit element.

In an example, referring specifically to the implementation diagram shown in fig. 8 for fig. 7, as shown in fig. 8, a located integrated circuit element is selected in a current view, specifically, a cross-located integrated circuit element is marked with a box in the current view, a view to be located and a corresponding element are selected in a search result list popped up after searching in a database index (i.e., a target search result is selected, specifically, a certain row or several rows in a click list are clicked), a form of "name of the integrated circuit element + element information + view information" is displayed in each row of the list (specifically, the name of the integrated circuit element + attribute information of the integrated circuit element + view where the integrated circuit element is located), that is, information indicating that the selected integrated circuit element is contained in the located view, the located integrated circuit element may not be the same type of integrated circuit element as the selected integrated circuit element, for example, an integrated circuit element is selected as a net in a view and a port is located in a view, but the located net is named the same as the port. And checking the corresponding element in the jumped positioning view. Therefore, the cross positioning of the corresponding integrated circuit elements in the database corresponding to the integrated circuit can be realized, the positionable integrated circuit elements can be completely displayed in a list form without repeatedly setting the cross positioning, and a user can select the elements according to the requirement, and the operation steps of the user are simple.

In particular, the following embodiments implement a scenario in which a target object is located in a view of an integrated circuit element, where the target object is the integrated circuit element.

1. And opening each database corresponding to the integrated circuit, and establishing a database index.

2. Opening a certain view of a certain unit in a certain database, selecting a certain integrated circuit element, for example, the integrated circuit element may be a Behavioral view under the opened oc8051_ alu unit, and selecting a wire mesh desCy in the Behavioral view of oc8051_ alu.

3. Searching the keyword desCy in a database index (specifically, a database index unit), and displaying the search result in a list, as shown in fig. 9, where the search result list corresponding to the desCy is specifically shown in fig. 10;

4. according to the selection operation of the target search result in the search result list, result information corresponding to the target search result can be obtained, and specifically, the view in which the integrated circuit element to be positioned is located and the integrated circuit element to be positioned in the view can be displayed.

In another example, it may also be that selecting option B in the list of fig. 10, locate Port desCy in Verilog view of oc8051_ alu unit in Verilog database, as shown in fig. 12;

in another example, the option C in the list of fig. 10 may be selected and located in an assign statement in the Behavioral view of the alu _ top unit in the Verilog database, which includes an assign statement to desCy, as shown in fig. 13.

It should be noted that, in each search result: element name + element information + view information, specifically in fig. 10 above, the @ symbol is preceded by: the type of integrated circuit element + the name of the integrated circuit element, followed by the @ symbol is the name of the view in which the integrated circuit element is located + the name of the cell.

In the technical scheme of the embodiment of the application, the integrated circuit element in the view is determined by responding to the selection operation of the integrated circuit element in the view by a user, index information corresponding to the integrated circuit element is searched in a pre-constructed database index to obtain a corresponding search result list, the search result list is displayed, and the view where the integrated circuit element to be positioned corresponding to the target search result is located and the integrated circuit element to be positioned in the view are displayed by responding to the selection operation of the target search result list on the target search result. Thus, by constructing database indexes in advance and linking all integrated circuit elements, the cross positioning of all integrated circuit elements in multiple databases can be realized, the search results of the integrated circuit elements can be completely displayed in a list form without repeatedly setting two views of the cross positioning, a user can select a target search result in a search result list according to the requirement and directly position the view of the integrated circuit element to be positioned corresponding to the target search result and the integrated circuit element to be positioned in the view, the operation is simple and convenient, the user experience is improved, and the positioning efficiency of the integrated circuit element among different views is also improved.

The case where the target object is a cell in a database and the target unit is a database will be described in detail below.

For the convenience of understanding the embodiment of the present application, first, the principle of locating a target object when the target object is a cell in a database and the target unit is a database will be described.

In another example, it may also be that selecting the D option in the list of FIG. 16 locates the Symbol view under the D _ AND2_6_4 element in the standard number element library FX04_ STD _ LIB _ SCH, as in FIG. 20.

It should be noted that, in each search result in the search result list corresponding to the unit: the cell name + the view information corresponding to the cell + the upper structure information of the cell, specifically in fig. 16, the @ symbol is preceded by: the name of the view corresponding to the cell + the name of the cell, and the @ symbol is followed by the superior structure type of the cell + the name of the database.
