The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments. In the following description, numerous specific details are provided to give a thorough understanding of embodiments of the present disclosure. One skilled in the relevant art will recognize, however, that the aspects of the disclosure may be practiced without one or more of the specific details, or with other methods, components, devices, steps, etc. In other instances, well-known technical solutions have not been shown or described in detail to avoid obscuring aspects of the present disclosure.

Furthermore, the drawings are merely schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus a repetitive description thereof will be omitted. Some of the block diagrams shown in the figures are functional entities and do not necessarily correspond to physically or logically separate entities. These functional entities may be implemented in software or in one or more hardware modules or integrated circuits or in different networks and/or processor devices and/or microcontroller devices.

The flow diagrams depicted in the figures are exemplary only and not necessarily all steps are included. For example, some steps may be decomposed, and some steps may be combined or partially combined, so that the order of actual execution may be changed according to actual situations. In addition, all of the following terms "first," "second," "third," "fourth," "fifth," and the like are for the purpose of distinction only and should not be construed as limiting the present disclosure.

In order to better illustrate the contents of the embodiments of the present disclosure, related concepts are described below.

The schematic circuit diagram (also called as electronic circuit diagram or circuit diagram) is a diagram which is drawn by using agreed symbols and represents the circuit structure, and can reflect the electric connection condition and working principle of each component in the electronic product, and is generally applied to the processes of designing circuits, analyzing circuits, improving circuits and the like. When the circuit is analyzed, the working principle of the circuit can be known by identifying various circuit element symbols drawn on the circuit schematic diagram and the connection mode between the circuit element symbols.

In some embodiments, the schematic circuit diagram may be composed of reference symbols, signal lines, nodes, and the like. Wherein, the element symbol represents the element in the actual circuit, the shape of the element is not necessarily similar to or even completely different from that of the actual element, but the element symbol generally represents the characteristics of the element, and the number of pins is consistent with that of the actual element. The signal line represents a wire in an actual circuit, and is a wire in a schematic circuit diagram, but is often not a wire in a common chip or a printed circuit board, but a metal wire with a certain width in various shapes. The nodes represent the connection relations among the pins of several components or the signal lines. All component pins and signal lines connected with the nodes are conductive no matter how many.

Layout (layout), also known as integrated circuit layout, circuit board diagram, etc., may be understood as being a mutually nested pattern that enables the final output of an integrated circuit design. The layout typically includes multiple layers, each of which may be identified with a different pattern. The layout is closely related to the fabrication process employed by the integrated circuit.

The connection line (net), which may be called a connection line, a connection net line, a net line, etc., at least includes a schematic circuit diagram and a signal line in a layout, and realizes connection between each circuit element (cell).

In the circuit verification stage or the circuit improvement stage, on one hand, a circuit designer needs to look up the layout of the wires in the layout and find out the reasons affecting the circuit performance. However, the layout has a plurality of layers, a complex structure, low manual searching efficiency and poor accuracy. On the other hand, the layout designer usually optimizes the layout of the wires according to the schematic diagram, and for large-scale schematic diagrams, the layout designer cannot quickly determine the distribution of the wires.

For a layout without a definite connection tag, a user cannot directly find a connection in the layout according to the connection name in the circuit schematic diagram, and needs to manually search a circuit unit connected with the connection, and then manually search a pin (port) for the circuit unit area of the layout to mark the connection, which is time-consuming and labor-consuming. Also, for a certain connection line of the layout, the position of the connection line on the circuit schematic diagram cannot be directly determined, complicated manual searching is needed, difficulty is brought to optimization and improvement of the circuit schematic diagram and the layout, and the research and development efficiency of the integrated circuit is reduced.

In view of this, the present disclosure provides a new scheme for finding connection lines between a schematic circuit diagram and a layout, which solves the problems of low efficiency and poor accuracy of finding connection lines at least to some extent.

FIG. 1 illustrates a schematic diagram of a scenario in which a connection is selected from a schematic circuit diagram and a corresponding connection is found in the layout, according to an embodiment of the present disclosure.

Referring to fig. 1, first, a user may select a connection X in a schematic circuit diagram; then, the electronic device may find a connection X in the layout corresponding to the schematic circuit diagram based on the selection result of the user, where the connection X is a connection corresponding to the connection X in the schematic circuit diagram in the layout.

FIG. 2 illustrates a schematic diagram of a scenario in which a connection is selected from a layout and a corresponding connection is found in a schematic diagram of a circuit in an embodiment of the present disclosure.

Referring to fig. 2, first, a user may select a connection y in a layout; then, the electronic device can find a connection line Y in the circuit schematic diagram corresponding to the layout based on the selection result of the user, wherein the connection line Y is a connection line corresponding to the connection line Y in the circuit schematic diagram.

According to the connection searching process, a user only needs to select a connection which is expected to be searched in the circuit schematic diagram, and the electronic equipment can automatically complete the connection searching process in the corresponding layout; or the user only needs to select the connection line which is expected to be searched in the layout, and the electronic equipment can automatically complete the connection line searching process in the corresponding circuit schematic diagram. Compared with the naked eyes of a user and a manual searching mode, the scheme of the online searching can improve the searching efficiency, and the searching accuracy is improved without artificial subjective or experience constraint.

Additionally, it should be understood that the wire lookup method of embodiments of the present disclosure may be performed by an electronic device. The electronic device may be, for example, a personal computer, a test device, a server, a cell phone, a tablet computer, etc. Specifically, the electronic device may be configured with a corresponding application program, and the selection operation of the user and the presentation of the search result may be implemented depending on the application program.

The connection searching method according to the embodiment of the present disclosure is described below.

Fig. 3 schematically illustrates a flow chart of a wire lookup method of an exemplary embodiment of the present disclosure. Referring to fig. 3, the connection finding method may include the steps of:

S32, determining a first connecting line in response to the connecting line selection operation.

According to some embodiments of the present disclosure, the connection selection operation may be an operation in which a user manually selects a connection. For example, the schematic circuit diagram and/or the connection lines in the layout may be displayed on the display screen of the electronic device, and the user may select the connection line desired to be searched by clicking with a mouse or clicking with a finger touch, so that for convenience of description, the disclosure marks the selected connection line as the first connection line.

According to other embodiments of the present disclosure, the wire selection operation may be an operation that the electronic device autonomously triggers in response to a lookup event. For example, in a scenario where it is verified whether the wiring of the schematic circuit diagram is consistent with the wiring in the layout, after the schematic circuit diagram and the layout are acquired, the electronic device may automatically trigger a wiring selection operation to search for each wiring or pre-designated wiring in the diagram, where each wiring or pre-designated wiring may be marked as a first wiring when the algorithm is executed. In this case, the search event may be the acquisition of both the schematic circuit diagram and the layout.

After determining the first connection, the electronic device may determine a circuit type of a circuit to which the first connection belongs. That is, the electronic device may determine whether the first connection is a connection in the schematic circuit diagram or a connection in the layout.

S34, under the condition that the first connecting line is a connecting line in the circuit schematic diagram, searching the connecting line corresponding to the first connecting line from the layout corresponding to the circuit schematic diagram according to the information of the circuit unit associated with the first connecting line in the circuit schematic diagram.

In an exemplary embodiment of the present disclosure, the information of the circuit unit associated with the first wire in the circuit schematic may include an instance name of the circuit unit associated with the first wire in the circuit schematic. Wherein the instance name (INSTANCE NAME) is also referred to as an instance name.

Fig. 4 shows a schematic diagram of a circuit schematic of an embodiment of the present disclosure. Referring to FIG. 4, I1-I8 may be example names of circuit elements.

The electronic device may look up the instance names of the circuit elements associated with the first connection from the layout corresponding to the schematic circuit diagram. In the case where there are instance names in the layout corresponding to the schematic diagram and circuit units corresponding to the instance names in the layout are connected by the second connection line, the second connection line in the layout is determined as a connection line corresponding to the first connection line in the schematic diagram.

For example, referring to fig. 4 and fig. 5, for the connection a, the circuit unit associated with the connection a in the circuit schematic may be determined, that is, the circuit unit a, the circuit unit b, and the circuit unit c are found, where pin1, pin2, and pin3 are ports (or pins) of the circuit units a, b, and c, respectively, and the positions of pins in the layout are generally marked with port information for indicating the connection relationship.

By checking the information of the layout, it can be determined that I1 and I2 are matched with the layout and I3 is not matched with the layout, and then the connection corresponding to the connection A in the circuit schematic diagram is found in the layout.

In the event that the instance names do not match to the corresponding connection lines, the electronic device may find the corresponding connection lines in conjunction with the type names of the associated circuit elements.

In these embodiments, the information of the circuit unit associated with the first connection in the circuit schematic further includes a type name of the circuit unit associated with the first connection. Referring to fig. 4, a circuit unit a (Cella), a circuit unit b (Cellb), a circuit unit c (Cellc), and a circuit unit e (Celle) are type names of the circuit units.

And searching for the connection corresponding to the first connection from the layout corresponding to the circuit schematic according to the type name of the circuit unit associated with the first connection in the circuit schematic when the instance name does not exist in the layout corresponding to the circuit schematic or the circuit unit corresponding to the instance name is not connected through the connection.

Specifically, when a type name exists in the layout corresponding to the circuit schematic diagram and the circuit units corresponding to the type name are connected through a third connecting line, determining the third connecting line as a connecting line corresponding to the first connecting line in the layout corresponding to the circuit schematic diagram; wherein the number of the third wires is one or more.

That is, one or more wires corresponding to the first wire may be found in the layout. In an embodiment of the present disclosure, these links are each output as a fuzzy search result of the first link.

Fig. 6 shows a schematic diagram of finding a wire in the layout that corresponds to wire B in the schematic diagram of the circuit shown in fig. 4.

For connection B in fig. 4, first, two circuit units are found in the schematic circuit diagram, and corresponding information is not matched in the layout by the instance names I3 and I4. Then, all the connection lines of the same connection relationship can be found out by using the type names of the circuit elements. Referring to fig. 4, the circuit unit c corresponds to I3, I5, and I8, and the circuit unit d corresponds to I4 and I5, so that the circuit unit c and the circuit unit d correspond to a total of 6 connection modes as shown in fig. 6, and two search results of "i3#pin4+i4#pin5" and "i8#pin4+i7#pin5" are determined through a matching process with layout information, that is, two connection lines are determined in the layout to correspond to the connection line B, and the two connection lines are fuzzy search results of the connection line B.

According to some embodiments of the present disclosure, in a case where a connection corresponding to a first connection is found in a layout corresponding to a schematic circuit diagram, an electronic device may construct a mapping relationship between the first connection in the schematic circuit diagram and the connection corresponding to the first connection in the layout, and configure the mapping relationship in a Graphical User Interface (GUI), so that mutual viewing between the connections may be achieved in response to a viewing operation on the graphical user interface.

It should be noted that in one embodiment, a graphical user interface may be configured for each link's search results. In another embodiment, the electronic device may also place the search results for all wires in the same graphical user interface. The present disclosure is not limited in this regard.

Fig. 7 shows a schematic diagram of a graphical user interface associated with the configuration link B corresponding to fig. 6. Referring to fig. 7, for fuzzy search results, both may be presented in a graphical user interface.

According to some embodiments of the present disclosure, in a case where a connection corresponding to a first connection is found in a layout corresponding to a schematic circuit diagram, an electronic device may change a display manner of the found connection or an area where the connection is located in the layout. For example, the electronic device may highlight the found connection in the layout to distinguish it from other connections. For another example, the electronic device may frame an area where the connection line found in the layout is located, so as to indicate the location of the connection line.

In addition, for the connection line found in the layout, the electronic device may also perform a zoom (zoom) operation on the layout to zoom in and/or focus on the found connection line.

According to some embodiments of the present disclosure, in a case where a connection corresponding to the first connection is not found in a layout corresponding to the schematic circuit diagram, the electronic device may generate a report that the connection is not found. That is, in the case where the instance names and the type names of the circuit elements that are associated as described above fail to match the corresponding wiring in the layout, the electronic device may generate a report in which the cause of not finding the corresponding wiring may be generated and display the report, for example, "Cellc not exist in layout" may be described in the report.

In the case where an instance name exists in the schematic circuit diagram corresponding to the layout and the circuit units corresponding to the instance name are connected through the fourth connection line, the fourth connection line in the schematic circuit diagram is determined as the connection line corresponding to the first connection line in the layout.

In the event that the instance names do not match to the corresponding connection lines, the electronic device may find the corresponding connection lines in conjunction with the type names of the associated circuit elements.

Under the condition that the example name does not exist in the circuit schematic diagram corresponding to the layout or the circuit units corresponding to the example name are not connected through the connecting wire, the electronic equipment can search the connecting wire corresponding to the first connecting wire from the circuit schematic diagram corresponding to the layout according to the type name of the circuit unit associated with the first connecting wire in the layout.

Specifically, when a type name exists in the circuit schematic diagram corresponding to the layout and the circuit units corresponding to the type name are connected through a fifth connecting line, determining the fifth connecting line as a connecting line corresponding to the first connecting line in the circuit schematic diagram corresponding to the layout; wherein the number of the fifth wires is one or more.

That is, one or more wires corresponding to the first wire in the layout may be found in the schematic circuit diagram. In an embodiment of the present disclosure, these links are each output as a fuzzy search result of the first link.

According to some embodiments of the present disclosure, in a case where a connection corresponding to a first connection is found in a schematic circuit diagram corresponding to a layout, an electronic device may construct a mapping relationship between the first connection in the layout and the connection corresponding to the first connection in the schematic circuit diagram, and configure the mapping relationship in a graphical user interface, so as to implement mutual viewing between the connections in response to a viewing operation on the graphical user interface.

It should be noted that in one embodiment, a graphical user interface may be configured for each link's search results. In another embodiment, the electronic device may also place the search results for all wires in the same graphical user interface. The present disclosure is not limited in this regard.

According to some embodiments of the present disclosure, in a case where a connection line corresponding to a first connection line is found in a schematic circuit diagram corresponding to a layout, an electronic device may change a display manner of the found connection line or an area where the connection line is located in the schematic circuit diagram.

For another example, the electronic device may frame the area where the connection line found in the schematic circuit diagram is located, so as to indicate the location of the connection line.

In addition, for the found connection in the schematic, the electronic device may also perform a zoom (zoom) operation on the schematic to zoom in and/or focus on the found connection.

According to some embodiments of the present disclosure, in the case where a connection corresponding to the first connection is not found in the schematic circuit diagram, the electronic device may generate a report that the connection is not found. That is, in the case where the example names and the type names of the circuit elements by the association described above fail to match the corresponding wirings in the circuit schematic, the electronic device may generate a report in which the cause of not finding the corresponding wirings may be generated and display the report, for example, "Cellc not exist IN SCHEMATIC" may be described in the report.
