In this method, the target circuit diagram drawn by the user in the graphical interface can be converted into the form of graph data that does not depend on a specific simulation analysis program and stored as an intermediate representation form. Thus, while being able to support the user's editing operations in the graphical interface and intuitively represent the topological structure between electronic components and the basic attributes of electronic components in the target circuit diagram, it can also be converted into netlist data in different formats supported by different simulation analysis software when simulation analysis is required, so as to facilitate flexible data exchange in different simulation analysis software and different functional modules, and further effectively reduce the cost of simulation analysis.

Description

Technical Field

[0001] This specification relates to the field of circuit simulation technology, and particularly to a method, apparatus, storage medium, and device for modeling, simulating, and analyzing circuit diagrams. Background Art

[0002] Modeling and simulation software is a tool for simulating and analyzing system performance. Through modeling and simulation software, testing and evaluating designs can be carried out without actually building or manufacturing physical prototypes, so as to reduce expensive physical tests and unnecessary iterations, thereby effectively improving the verification efficiency while reducing the verification cost and risk, and thus making the modeling and simulation software an irreplaceable engineering simulation software and teaching software. In the actual use process, users can, through the rich electronic components provided by the modeling and simulation software, such as power supplies, resistors, inductors, pulleys, etc., and after simply setting component parameters and simulation time, etc., observe the circuit state at any time. Among them, relatively well-known modeling and simulation software includes Modelica, matlab, Simulink, etc.

[0003] However, since different modeling and simulation software usually adopts its own unique data format to represent circuit diagram data. These data formats are often tailored for specific software or simulation environments, focusing on meeting the internal needs of the software and optimizing performance. Although this proprietary data format design improves the software operation efficiency to a certain extent, it also brings obvious limitations. When users need to migrate circuit design data to a new simulation environment or integrate with other software, the existing data formats are often difficult to directly expand or adapt, resulting in users needing to re-model, thus greatly increasing the cost of simulation analysis.

[0004] Therefore, how to reduce the cost of simulation analysis is an urgent problem to be solved. Summary of the Invention

[0051] To make the objectives, technical solutions and advantages of this specification clearer, the technical solutions of this specification will be clearly and completely described below in conjunction with specific embodiments of this specification and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this specification, rather than all the embodiments. Based on the embodiments in this specification, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the scope of protection of this specification.

[0052] The following will detail the technical solutions provided in each embodiment of this specification in conjunction with the drawings.

[0053] Figure 1 Schematic diagram of the flow of a circuit diagram modeling and simulation analysis method provided in this specification, including the following steps:

[0054] S101: Display a preset model library through a preset graphical interface, and obtain the layout operation instructions executed by the user for different models included in the model library, where the models are used to represent the electronic components required for constructing a circuit diagram.

[0055] In this specification, the service platform can provide a preset model library to the user through a preset graphical interface, so that the user can execute layout operation instructions for different models included in the model library in the graphical interface, such as dragging, text editing, clicking, etc. Then, according to the layout operation instructions sent by the user, the models selected by the user can be determined, and the definition data configured by the user for the selected models can be determined. Furthermore, according to the models selected by the user and the definition data of the models, a target circuit diagram can be constructed in the circuit diagram drawing canvas, and simulation analysis can be performed based on the constructed target circuit diagram.

[0056] Among them, the above models may refer to the symbols of electronic components required for constructing a circuit diagram and the connection line tools for connecting these electronic components provided by the service platform to the user in advance. Here, the electronic components may be, for example: power supplies, resistors, capacitors, transistors, etc.

[0057] The defined data of the above model may refer to the data used to describe the basic attributes of the electronic components corresponding to the model in circuit design and simulation, as well as the necessary information such as the connection method of the model. Such as: component name, manufacturer name, model number, electrical characteristic parameters (such as: resistance value, rated power, capacitance value, withstand voltage value, etc.), size, pin layout (the model can have multiple pins for connecting with other models, and the pins here can refer to the metal joint points on the model), connection method, etc.

[0058] It should be noted that among the models included in the model library, the defined data of some models may be fixed. Of course, the defined data of some models may also be user-defined. At this time, the business platform can set basic defined data for each model in the model library, so that when the user needs to customize the defined data of at least some of the selected models, the user can, based on the basic defined data of the model for which the defined data needs to be customized, execute the layout operation instruction for the model for which the defined data needs to be customized in the graphical interface to obtain the modified defined data of the model for which the defined data needs to be customized, so that the business platform can construct the target circuit diagram according to the modified defined data of the model.

[0059] In this specification, the execution entity for implementing the circuit diagram modeling and simulation analysis method may refer to a specified device such as a server set in the business platform, or may refer to terminal devices such as desktop computers and laptop computers. For the convenience of description, hereinafter, only the case where the server is the execution entity will be used as an example to describe the circuit diagram modeling and simulation analysis method provided in this specification.

[0060] S102: According to the layout operation instruction, construct a target circuit diagram, and parse the target circuit diagram to obtain the graph basic data corresponding to the target circuit diagram; each node in the graph basic data is used to represent each graph element included in the target circuit diagram, and the graph elements include: electronic components and the connections between electronic components; each edge in the graph data is used to represent the connection relationship between two graph elements.

[0061] It should be noted that in this specification, component entity representation data, line representation data, and connection point representation data can be used to represent the component entities, lines, and connection points included in different circuit diagrams.

[0062] Among them, the component entity may refer to an electronic component extended from the model for actual circuit diagram drawing. There are multiple pins on the component entity for connecting between component entities. The pins here can be the metal joint points on the entity for connecting different component entities.

[0063] In the above content, the lines can refer to the connections between various electronic components in a circuit diagram. These lines can be straight lines, curves, broken lines, or other forms, and their function in the circuit diagram is to show the flow direction and connection relationship of current, signals, or power supplies.

[0064] In the above content, the joint point Joint can refer to the connection point of two or more lines or conductors in a circuit. The joint point can be a physical connection between different parts or components in the circuit, which allows current or signals to be transmitted from one part to another.

[0065] It can be seen from the above content that through the above circuit structure data, a data representation of a complex circuit diagram can be completely defined. For the convenience of understanding, the following combines Figure 2 to elaborate on the above circuit structure data in detail.

[0066] Figure 2 is a schematic diagram of the circuit structure data provided in this specification.

[0067] Combined with Figure 2 it can be seen that for each component entity data Entity, it can include definition data Model of the model and attributes such as pins Pins. For each line representation data Edge, it can include attributes such as start joint Start Joint and end joint End Joint.

[0068] It can be seen from the above content that the server can represent the target circuit diagram through component entity representation data Entity, line representation data Edge, and connection point representation data Joints.

[0069] Based on this, the server can construct the target circuit diagram according to the layout operation instructions executed by the user in the graphical interface, and then can parse the target circuit diagram to obtain the circuit structure data used to characterize the target circuit diagram.

[0070] Furthermore, after the server obtains the circuit structure data used to characterize the target circuit diagram, it can convert according to the circuit structure data to obtain each node included in the target circuit diagram and the node features of each node, so as to obtain the graph basic data corresponding to the target circuit diagram, and then can store the graph structure of the target circuit diagram through the graph data.

[0071] Specifically, the server can create a node corresponding to each graph element included in the target circuit diagram according to the component entity representation data or line representation data of the graph element, and then can determine the node features of the node corresponding to the graph element according to the attributes of the component entity representation data or line representation data of the graph element, and the connection point representation data included in the graph element.

[0072] Among them, for each graphic element corresponding to an electronic component included in the target circuit diagram, if the connection points included in the graphic element indicate that the connection points included in the graphic element corresponding to the connection line between the data and the electronic component represent the same data, it can be considered that the graphic element is connected to the graphic element corresponding to the connection line between the above-mentioned electronic components through the connection points represented by the data included in the graphic element. At this time, it can be determined that the node used to represent the graphic element in the above-mentioned graphic basic data and the node used to represent the graphic element corresponding to the connection line between the above-mentioned electronic components are connected by an edge. And so on, the server can convert and obtain the graphic basic data corresponding to the target circuit diagram according to the circuit structure data and store it.

[0073] In actual application scenarios, the formats of the netlist data used by different simulation analysis programs are often different. For example: SPICE netlist, Verilog netlist, EDIF netlist, etc. At this time, for each format of netlist data, a conversion program for converting the graphic basic data into the netlist data of this format can also be preset in the server. In the case of receiving a simulation analysis instruction for the target circuit diagram, the format of the netlist data that needs to be converted can be determined according to the simulation analysis instruction as the target format. Furthermore, the conversion program that matches the target format can be determined from the preset conversion programs, and the graphic basic data can be converted into the netlist data required for interacting with the simulation analysis program through the conversion program that matches the target format.

[0074] It should be noted that since the simulation analysis tasks performed by users when performing simulation analysis on different circuit diagrams may be different (for example: in the circuit performance simulation analysis task, basic parameters such as the voltage, current, and power of the circuit need to be simulated and analyzed. In the signal integrity simulation analysis task, the transmission quality of signals in the circuit needs to be analyzed, including: reflection, crosstalk, attenuation, etc.), and the execution logics of different simulation analysis tasks are often different, so code programs for executing different task logics often need to be deployed in the server, which makes it often difficult to manage and maintain these code programs.

[0075] Therefore, in this specification, the code programs of the above different task logics and the conversion programs in the above content can be deployed in different processors, and these processors can be stored in a chained structure. As a result, when the server receives a simulation analysis instruction for a target circuit diagram, it can generate a task request according to the received simulation analysis instruction for the target circuit diagram, and send the task request to each processor in sequence according to the order among the processors included in the preset processing flow chain until the task request is sent to the target processor that matches the task request, so that the target processor can determine the port number representations corresponding to the various electronic components included in the graph basic data according to the edges included in the graph basic data.

[0076] S103: When receiving a simulation analysis instruction for the target circuit diagram, determine the port number representations corresponding to the various electronic components included in the graph basic data according to the edges included in the graph basic data, where the port number representations are used to characterize the connection relationships between electronic components.

[0077] S104: According to the graph basic data and the port number representations, convert the graph basic data into netlist data required for interaction with the simulation analysis program, so that the simulation analysis software can perform simulation analysis on the target circuit diagram based on the netlist data.

[0078] In this specification, when the server determines that it is necessary to perform simulation analysis on a target circuit diagram, it can obtain the graph basic data corresponding to the target circuit diagram, and then can determine the port number representations corresponding to the various electronic components included in the target circuit diagram according to the edges included in the graph basic data. Furthermore, according to the graph basic data and the port number representations corresponding to the various electronic components included in the target circuit diagram, the graph basic data can be converted into netlist data required for interaction with the simulation analysis program, so as to perform simulation analysis on the target circuit diagram based on the netlist data.

[0079] Among them, there can be various conditions for the server to determine that it is necessary to perform simulation analysis on a target circuit diagram. For example, when receiving a simulation analysis instruction for the target circuit diagram, a task request can be generated according to the simulation configuration parameters set by the user (such as simulation time, simulation step size, analysis type, etc.), and then it can be determined that it is necessary to perform simulation analysis on the target circuit diagram according to the task request.

[0080] For another example: when the user inputs or adjusts the simulation configuration parameters in the graphical interface, the server can automatically determine that it is necessary to perform simulation analysis on the target circuit diagram when monitoring the changes in these parameters.

[0081] In the above content, the method for determining the port number representation corresponding to each electronic component included in the target circuit diagram based on the edges included in the graph basic data can be that the server selects a first target node (i.e., the node used to represent the electronic component) from each node of the graph basic data, and then can construct instance objects (each instance object is used to represent each electronic component in the target circuit) according to the node characteristics of the first target node, and determine the connection points included in the instance object. Then, according to the order of the connection points included in each instance object, port numbers can be assigned to the connection points included in each instance object.

[0082] Furthermore, the server can determine the port number representation corresponding to each electronic component included in the graph basic data according to the port numbers of the connection points included in each instance object, specifically as Figure 3A shown.

[0083] Figure 3A This is a schematic diagram of the port numbers of the connection points provided in this specification.

[0084] In Figure 3A the shown target circuit diagram, there are 4 electronic components, namely a single-phase sinusoidal AC voltage source, a resistor, an ammeter, a voltage probe, and a special component ground. Among them, the single-phase sinusoidal AC voltage source has 2 connection points, the voltage probe has 1 connection point, the resistor has 2 connection points, the ammeter has 2 connection points, and the ground has 1 connection point.

[0085] At this time, the server can select the first target nodes corresponding to the single-phase sinusoidal AC voltage source, resistor, ammeter, and voltage probe from each node of the graph basic data, and construct instance objects of the single-phase sinusoidal AC voltage source, resistor, ammeter, and voltage probe according to the node characteristics of the first target node, and determine the connection points included in each instance object. Then, according to the order of the connection points, port numbers can be assigned to the connection points included in each instance object. As Figure 3A shown, the connection point with port number 1 and the connection point with port number 2 included in the single-phase sinusoidal AC voltage source, the connection point with port number 3 included in the voltage probe, the connection point with port number 4 and the connection point with port number 5 included in the resistor, and the connection point with port number 6 and the connection point with port number 7 included in the ammeter.

[0086] Among them, the order of the connection points can refer to the order of traversing each connection point of different instance objects.

[0087] In the above content, according to the sequence of the connection points, the method of allocating port numbers to the connection points included in each instance object can be to allocate port numbers to the connection points included in each instance object in ascending order according to the sequence of the connection points.

[0088] Further, after the server sequentially allocates port numbers to the connection points included in each instance object, it is also necessary to linearly and recursively traverse each second target node in the graph basic data to determine, for each instance object, other instance objects connected to this instance object through the connection lines represented by the second target node, and determine the connection points used when connecting to other instance objects from the connection points of this instance object, and reset the port numbers of the connection points of this instance object and the port numbers of the connection points of other instance objects to the same port number.

[0089] Among them, the reset port number is used to represent that this instance object is connected to other instance objects through the connection points corresponding to the reset port number.

[0090] Further, the server can determine the port number representations corresponding to the respective electronic components included in the graph basic data according to the port numbers of the connection points included in each instance object after reset. Specifically, as Figure 3B shown.

[0091] Figure 3B This is a schematic diagram of the port numbers of the connection points after reset provided in this specification.

[0092] Combined with Figure 3B it can be seen that for the instance object corresponding to the single-phase sinusoidal AC voltage source, the connection point with a port number of 1 of this instance object is connected through a connection line to the connection point with a port number of 3 of the instance object corresponding to the voltage probe and the connection point with a port number of 4 of the instance object corresponding to the resistor. At this time, the connection points with a port number of 1, a port number of 3, and a port number of 4 can be used as connection points. Furthermore, by resetting the port numbers corresponding to the above three connection points to the same port number, it is used to represent that the instance object corresponding to the single-phase sinusoidal AC voltage source, the instance object corresponding to the voltage probe, and the instance object corresponding to the resistor are connected through the connection line and the connection points corresponding to the reset port number.

[0093] Specifically, the server can determine, according to the sequence of each instance object, to use the port number of the connection point of the instance object corresponding to the single-phase sinusoidal AC voltage source as the reset port number of the above three connection points, that is, set the port numbers of the connection points with a port number of 3 and a port number of 4 to 1.

[0094] It should be noted that for each electronic component, when a certain connection point in the electronic component is connected to the connection points of other electronic components through a wire, the connection point used to connect to the wire is the connection point.

[0095] In addition, in actual application scenarios, the circuit diagrams drawn by users often also include special components, such as: ground, input / output ports, etc.

[0096] At this time, when the server determines that there is an instance object of the specified type among the instance objects, the server can also reset the port number of the instance object of the specified type to a specified value (the above-mentioned specified value can be set according to actual needs, for example: 0). Furthermore, based on the reset port number, the server can determine the port number representation of the electronic component corresponding to the instance object of the specified type included in the graph basic data, and based on the port numbers of the connection points included in each instance object determined again, determine the port number representation of each electronic component included in the graph basic data.

[0097] It is worth noting that for each electronic component, the port number representation of the electronic component is used to characterize the connection relationship between the electronic component and other electronic components.

[0098] For example: in Figure 3B , in the single-phase sinusoidal AC voltage source, the connection point with port number 1 and the connection point with port number 2 are connected to other electronic components. At this time, the port number representation of the single-phase sinusoidal AC voltage source is (1, 2). By analogy, it can be known that the port number representation of the resistor is (1, 5). Furthermore, based on the port number representation of the single-phase sinusoidal AC voltage source and the port number representation of the resistor, it can be known that the single-phase sinusoidal AC voltage source is connected to the connection point with port number 1 in the resistor through the connection point with port number 1 and a wire.

[0099] Furthermore, the server can convert the graph basic data into netlist data required for interacting with the simulation analysis program according to the graph basic data and the port number representation.

[0100] For example: The partial netlist data used to characterize the above-mentioned single-phase sinusoidal AC voltage source can be {"label": "AC", "name": "AC1", "index": 1, "type": "ELECTRIC", "ports": [1, 2]}. By analogy, the netlist data used to characterize the target circuit diagram can be obtained.

[0101] It should be noted that the above-mentioned netlist data can include features such as nodes (Elements), ports (Ports), attributes (Attributes), etc.

[0102] Among them, nodes are used to represent various logic gates, devices, input / output ports, etc. in a circuit. Each node has a unique identifier and name, which are used to correspond to the basic components in the target circuit diagram.

[0103] Ports are used to represent the connections between various nodes in a circuit. The number of ports represents the number of connection points. When the port numbers are the same, it means they are connected in the circuit.

[0104] In addition, the attributes of each node or wire in the netlist data are used to describe additional information such as the characteristics, functions, and physical locations of the node or wire.

[0105] For example, a node can have different logic functions (such as AND, OR, NOT, etc.), or can have different basic attributes (switch closed state, resistance, capacitance, etc.).

[0106] For the sake of easy understanding, the following details the call relationships during the simulation analysis process of the circuit diagram modeling and simulation analysis method described above, specifically as Figure 4 shown.

[0107] Figure 4 This is a schematic diagram of the process of circuit diagram simulation analysis provided in this specification.

[0108] Combined with Figure 4 It can be seen that the user can construct the target circuit diagram on the circuit diagram drawing canvas provided in the graphical interface by executing layout operation instructions for different models included in the model library in the graphical interface, selecting different electronic components, and connecting the electronic components after configuring the definition data of each electronic component.

[0109] The server can parse the target circuit diagram drawn by the user by calling the server-side process, obtain the graph basic data corresponding to the target circuit diagram, and store it.

[0110] Furthermore, when the server determines that simulation analysis needs to be performed on the target circuit diagram, it can call the server-side process to convert the graph basic data corresponding to the target circuit diagram into the netlist data required for interaction with the simulation analysis program. Furthermore, it can call the computing-side process to perform simulation analysis based on the netlist data corresponding to the target circuit diagram and obtain the simulation analysis result.

[0111] It should be noted that the above simulation analysis result can be timing representation data, that is, the calculation result used to represent the change of target parameters (such as current, voltage) over time within a specified time period.

[0112] As can be seen from the above method, the server can convert the target circuit diagram drawn by the user in the graphical interface into the form of graph data that does not depend on a specific simulation analysis program, and store it as an intermediate representation form. Thus, while being able to support the editing operations of the user in the graphical interface and visually represent the topological structure between the electronic components and the basic attributes of the electronic components in the target circuit diagram, it can also be converted into netlist data in different formats supported by different simulation analysis software when simulation analysis is required, so as to facilitate flexible data exchange in different simulation analysis software and different functional modules, and further effectively reduce the cost of simulation analysis.

[0113] The above is a method for modeling and simulating analysis of one or more implementation circuit diagrams in this specification. Based on the same idea, this specification also provides a corresponding device for modeling and simulating analysis of circuit diagrams, as Figure 5 shown.

[0114] Figure 5 is a schematic diagram of a device for modeling and simulating analysis of a circuit diagram provided in this specification, including:

[0115] An acquisition module 501, configured to display a preset model library in a preset graphical interface, and acquire layout operation instructions executed by the user for different models included in the model library, where the models are used to represent electronic components required for constructing a circuit diagram and connection tools for connecting the electronic components;

[0121] Optionally, the determination module 503 is specifically configured to generate a task request when receiving a simulation analysis instruction for the target circuit diagram; when it is determined according to the task request that a simulation analysis needs to be performed on the target circuit diagram, send the task request to each processor in sequence according to the order among the processors included in a preset processing flow chain until the task request is sent to a target processor that matches the task request, so that the target processor determines the port number representation corresponding to each electronic component included in the graph basic data according to the edges included in the graph basic data; where different processors in the processing flow chain are used to execute different simulation analysis tasks in response to different task requests.

[0122] Optionally, the determination module 503 is specifically configured to select a first target node from each node of the graph basic data, where the first target node is used to characterize an electronic component; construct an instance object according to the node features of the first target node, and determine the connection points included in the instance object; assign port numbers to each connection point according to the order among the connection points; and determine the port number representation corresponding to each electronic component included in the graph basic data according to the port number of each connection point.

[0125] This specification also provides a computer-readable storage medium, which stores a computer program, and the computer program can be used to execute the above Figure 1 provided method for modeling and simulating analysis of a circuit diagram.

[0126] This specification also provides Figure 6 a schematic structural diagram of an electronic device corresponding to Figure 1 . As Figure 6 described above, at the hardware level, the electronic device includes a processor, an internal bus, a network interface, a memory, and a non-volatile memory. Of course, it may also include other hardware required for other services. The processor reads the corresponding computer program from the non-volatile memory into the memory and then runs it to implement the above Figure 1 described method for modeling and simulating analysis of a circuit diagram. Of course, in addition to the software implementation manner, this specification does not exclude other implementation manners, such as a logic device or a combination of software and hardware, etc. That is to say, the execution subject of the following processing flow is not limited to each logic unit, and may also be hardware or a logic device.

[0127] For an improvement in a technology, it can be clearly distinguished whether it is a hardware improvement (e.g., improvement in circuit structures such as diodes, transistors, switches, etc.) or a software improvement (improvement in method processes). However, with the development of technology, many improvements in method processes today can be regarded as direct improvements in hardware circuit structures. Almost all designers obtain the corresponding hardware circuit structure by programming the improved method process into the hardware circuit. Therefore, it cannot be said that an improvement in a method process cannot be implemented with a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logic function is determined by the user programming the device. The designer can program by himself to "integrate" a digital system on a piece of PLD, without having to ask a chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing. The original code before compilation also has to be written in a specific programming language, which is called a hardware description language (HDL), and there is not only one kind of HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. Currently, the most commonly used are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be aware that by simply performing a little logical programming on the method process with the above-mentioned several hardware description languages and programming it into the integrated circuit, it is easy to obtain the hardware circuit that implements the logical method process.

[0128] The controller can be implemented in any suitable manner. For example, the controller can take the form of, for example, a microprocessor or a processor and a computer-readable medium storing computer-readable program code (such as software or firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of the controller include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in the form of pure computer-readable program code, it is entirely possible to logically program the method steps to enable the controller to implement the same functions in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, and embedded microcontrollers. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be regarded as structures within the hardware component. Or even, the devices for implementing various functions can be regarded as either software modules for implementing the method or structures within the hardware component.

[0129] The systems, devices, modules, or units illustrated in the above embodiments can be specifically implemented by computer chips or entities, or by products with certain functions.

[0138] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device.
