Description

  The present invention relates to a component selection support apparatus, a control method thereof, and a program for assisting a designer of an electrical circuit to select components constituting the electrical circuit when designing the electrical circuit.

  In designing an electric circuit, a designer of an electric circuit first selects parts constituting the electric circuit. In many cases, main parts, such as a CPU (Central Processing Unit) and an FPGA (Field Programmable Gate Array), which are parts that control the main operation of an electric circuit, are determined at the stage of determining specifications. In addition, a functional block diagram that connects multiple circuit blocks centered on main components to meet the specifications and a power system diagram for supplying power to each circuit block (also called a power distribution diagram or power supply system diagram) are also available. Often fixed. Here, the circuit block refers to a circuit composed of a main part and a number of subordinate parts such as a resistor, a capacitor, and a coil connected to the main part in order to make the main part function.

  Usually, specifications of subordinate parts connected to main parts of the circuit block are defined by the main parts. The designer selects subordinate parts or the like according to the main parts determined according to the specification, and writes down a functional block diagram, a power supply system diagram, etc. to a specific electric circuit.

  In designing an electric circuit, a diversion design is often performed in which a part of a designed circuit is changed to design a desired electric circuit. The diverted design can reduce the effort for the designer to select parts or create an electric circuit. However, even when a diversion design is performed, it may be necessary to select a large number of parts, for example, due to a major change in dependent parts due to a change in main parts. The selection of many parts is time consuming for the designer.

  In addition, in the development and design departments of devices such as electronic devices, the parts handled in that department are usually standardized and managed in order to prevent defects and reduce the cost of materials. A grade called a part rank is set. The component rank is set in consideration of cost, procurement stability, reliability, etc., and is recommended for use, recommended for use, permitted for use, and prohibited for use. Etc. are set. For example, if a malfunction occurs due to a certain part, the part rank of that part is prohibited, or if a part is revised, the part rank of the current part is used from the recommended use It is changed to permission, and the part rank of the successor part is set to recommended use. In this way, the component rank is changed as appropriate. Therefore, every time a designer selects a part, it is necessary to confirm whether or not the use of the part is prohibited, which takes time.

  Patent Document 1 (Japanese Patent Application Laid-Open No. 2002-032422) discloses a system for creating a parts table indicating the identifiers of parts constituting a printed wiring board and the number of the parts, and the parts to the parts table in units of circuit blocks. A technique for performing addition / deletion is disclosed. According to this technology, when a part of a circuit block of a designed electrical circuit is replaced with another circuit block, parts are added to or deleted from the parts list in units of circuit blocks, and the parts list is simplified. Can be created.

  Patent Document 2 (Japanese Patent Laid-Open No. 2009-223684) stores mounting conditions such as a wiring length and a wiring width in which a reference circuit can be mounted, and the configuration of the electrical circuit to be designed is the configuration of the reference circuit. In the case of the same, the technology for notifying the designer of the mounting conditions of the reference circuit is disclosed. According to this technique, it is possible to design an electric circuit from the design stage in consideration of restrictions in the mounting stage.

  Further, in Patent Document 3 (Japanese Patent Laid-Open No. 04-277864), it is determined whether or not a part described in the parts table is registered as a standard part. Techniques for selecting alternative parts are disclosed. According to this technique, even when a part described in the parts table is not a standard part, an alternative part of the part can be presented to the designer.

  EMBODIMENT OF THE INVENTION Below, the form for implementing this invention is demonstrated with reference to drawings.

  FIG. 1 is a diagram showing a schematic configuration of a component selection support apparatus 10 according to an embodiment of the present invention.

  A component selection support apparatus 10 shown in FIG. 1 includes a component information DB (Database) 101, a standard circuit DB 102, a specification input unit 103, a specification analysis unit 104, a standard circuit reading unit 105, and a standard component determination unit. 106, a display unit 108, a parts table creation support unit 109, and a standard circuit registration unit 110. The specification analysis unit 104, the standard circuit reading unit 105, and the standard part determination unit 106 constitute a control unit 107. The component information DB 101 is an example of a first storage unit, the standard circuit DB 102 is an example of a second storage unit, and the control unit 107 is an example of a control unit. Each block illustrated in FIG. 1 does not necessarily indicate specific hardware or software, and may indicate a conceptual block having a specific function.

  The parts information DB 101 is a specification of parts standardized as parts (including not only parts constituting an electric circuit but also parts constituting the apparatus such as screws and resin) used in the department in the development and design department of the apparatus. Remember. In addition, the component information DB 101 stores a component rank for using the component, a reason for setting the component rank, and the like corresponding to each component. As the component rank, for example, use recommendation indicating that use is recommended, use permission indicating that use is permitted, use prohibition indicating that use is prohibited, and the like are set. Whether or not a part can be used is indicated by the part rank. Hereinafter, a part for which a rank indicating that the part can be used is set as a part rank is referred to as a standard part.

  The standard circuit DB102 is a standard circuit that is a circuit block in which subordinate components such as a resistor, a capacitor, and a coil are connected to main components so that main components such as a CPU and FPGA that control main operations of the electric circuit function, and A component parts table showing the parts constituting the standard circuit is stored. Here, for example, basic information such as a manufacturer model number of a main part constituting the standard circuit or a unique model number within a department is used as an identifier for identifying the standard circuit.

  The specification input unit 103 receives input of specification information indicating the specification of the electrical circuit to be designed, and outputs the specification information to the specification analysis unit 104. Here, as the specification information, there are a functional block diagram in which a plurality of circuit blocks are connected and a power supply system diagram for supplying power to each circuit block, which are determined according to required specifications. The functional block diagram and the power system diagram show the main parts of the electrical circuit to be designed. In addition, the specification information may include information that defines the position of the device, such as the device name, the use of the device, the use environment, the processing capability, and the diversion source device name.

  Note that the specification information input method may be a method of inputting manually, a method of importing specification information created in advance with electronic data, or a method of combining both. In addition, the specification information may include indeterminate information. The functional block diagram and power supply system diagram may be handwritten. When the functional block diagram or the power supply system diagram is handwritten, processing such as character recognition using an OCR (Optical Character Reader) or the like is required.

  The specification analysis unit 104 specifies the main parts indicated in the specification information input from the specification input unit 103, creates a main parts list indicating the specified main parts, and outputs it to the standard circuit reading unit 105.

  The standard circuit reading unit 105 reads the standard circuit including the main parts shown in the main part list input from the specification analysis unit 104 and the component parts table of the standard circuit from the standard circuit DB 102, and reads the standard circuit. The component parts table is output to the display unit 108 and the parts table creation support unit 109.

  In response to a request from the specification analysis unit 104 or the standard circuit reading unit 105, the standard component determination unit 106 determines whether the target component is a standard component and outputs the determination result to the request source. Specifically, the standard component determination unit 106 reads the component rank of the target component from the component information DB 101, and determines whether or not the component is a standard component based on the read component rank.

  When the standard circuit determination unit 106 receives a circuit diagram of a circuit block and a registration request as a standard circuit of the circuit block from the standard circuit registration unit 110, the components constituting the circuit block are standard components. It is determined whether or not there is a component, and if all the components constituting the circuit block are standard components, the standard block DB 102 stores the circuit block and the component parts table indicating the components constituting the circuit block.

  The display unit 108 displays various information according to the control of the control unit 107 and notifies the designer of the information. For example, when information indicating the standard circuit and the component parts table is input from the standard circuit reading unit 105, the display unit 108 displays the standard circuit and the component parts table.

  The parts table creation support unit 109 creates and outputs a parts table based on the standard circuit input from the standard circuit reading unit 105 and information indicating the component parts table.

  The standard circuit registration unit 110 receives an instruction to create or edit a circuit diagram from the designer, and causes the display unit 108 to display a circuit diagram corresponding to the instruction using CAD (Computer Acid Design). When the standard circuit registration unit 110 inputs that the circuit block is registered as a standard circuit, the standard circuit registration unit 110 outputs a circuit diagram of the circuit block and a registration request as the standard circuit of the circuit block to the standard component determination unit 106. To do.

  Next, the operation of the component selection support apparatus 10 of this embodiment will be described.

  In the following, the configuration of the component selection support apparatus 10 is a server / client configuration, and as illustrated in FIG. 2, the component information DB 101, the standard circuit DB 102, the specification analysis unit 104, the standard circuit reading unit 105, and the standard component determination The unit 106 is provided on the server side, and the specification input unit 103, the display unit 108, the parts table creation support unit 109, and the standard circuit registration unit 110 are provided on the client (designer) side. explain. However, the configuration of the component selection support apparatus 10 according to the present invention does not have to be a server / client configuration, and all configurations may be provided on the client side.

  First, the operation at the time of specification information analysis will be described with reference to the flowchart shown in FIG.

  When the specification information is input via the specification input unit 103, the specification analysis unit 104 determines whether or not all the main parts have been specified from the functional block diagram and the power supply system diagram shown in the specification information. (Step S301).

  If all the main parts have not been specified (step S301: No), the specification analysis unit 104 specifies the main parts from the functional block diagram and the power system diagram (step S302).

  Next, the specification analysis unit 104 outputs main part information indicating the identified main part to the standard part determination unit 106, and requests a determination as to whether or not the main part is a standard part. In response to the request from the specification analysis unit 104, the standard component determination unit 106 reads a component rank corresponding to the main component indicated in the main component information from the component information DB 101, and based on the read component rank, the main component Is a standard part (step S303), and the determination result is output to the specification analysis unit 104.

  When the determination result indicates that the main part indicated in the main part information is not a standard part (step S303: No), the specification analysis unit 104 stops the analysis and indicates that an error has occurred (main part that is not a standard part). The display unit 108 is caused to display a message that the component is included (step S304).

  When the determination result indicates that the main part indicated in the main part information is a standard part (step S303: Yes), the specification analysis unit 104 returns to the process of step S301.

  When all the main parts are specified (step S301: Yes), the specification analysis unit 104 creates a main part list indicating the specified main parts (step S305) and outputs the list to the standard circuit reading unit 105. Further, the specification analysis unit 104 causes the display unit 108 to display that the analysis has been completed (step S306). The main parts list includes at least basic information that can uniquely identify the main parts, such as the manufacturer's model number of the main part and the unique model number within the department. Physical property information such as rated voltage, rated current, and capacity value of the main part, size Information such as the implementation method can also be included.

  Next, the operation at the time of standard circuit reading will be described with reference to the flowchart shown in FIG.

  When the main component list is input, the standard circuit reading unit 105 performs the following processing for each main component shown in the main component list.

  First, the standard circuit reading unit 105 determines whether or not there is a record of registration of the standard circuit of the main part in the standard circuit DB 102 (step S401). Specifically, the standard circuit reading unit 105 uses the basic information that can uniquely identify the main part, such as the manufacturer's model number of the main part and the department-specific model number shown in the main part list, to match the basic information. A standard circuit is searched from the standard circuit DB 102, and if there is a standard circuit whose basic information completely matches, it is determined that there is a record of registration (step S401: Yes). Further, the standard circuit reading unit 105 reads the retrieved standard circuit and the component table of the standard circuit from the standard circuit DB 102.

  Next, the standard circuit reading unit 105 requests the standard component determination unit 106 to determine whether or not the component shown in the read component table is a standard component. In response to the request from the standard circuit reading unit 105, the standard component determination unit 106 reads the component rank of the component shown in the component table from the component information DB 101, and the component is a standard component based on the read component. (Step S402), and outputs the determination result to the standard circuit reading unit 105. Details of the determination process performed by the standard component determination unit 106 will be described later.

  The standard circuit reading unit 105 causes the display unit 108 to display the standard circuit that has read the determination result of the standard component determination unit 106 and the component parts table. Specifically, when the determination result of the standard component determination unit 106 indicates that all the components shown in the component parts table are standard components (step S402: Yes), the standard circuit reading unit 105 reads the standard that has been read. The circuit and the component table are displayed on the display unit 108 (step S403).

  When the determination result indicates that some or all of the parts shown in the component parts table are not standard parts (step S402: No), the standard circuit reading unit 105 determines that the parts that are not standard parts are After adding an error attribute indicating that the part is not a standard part (step S404), the process proceeds to step S403.

  In the present embodiment, a part determined not to be a standard part is displayed with a determination result indicating whether or not the part is a standard part (error attribute indicating that the part is not a standard part). However, a part that is determined to be a standard part may be displayed with an indication that the part is a standard part.

  If there is no record of registration of the standard circuit of the main part (step S401: No), the standard circuit reading unit 105 determines whether or not there is a reference circuit of the main part (step S405). Specifically, the standard circuit reading unit 105 inquires of the component information DB 101 whether or not the reference circuit of the main component is registered. Usually, a circuit block for causing the main part to function is often described as a reference circuit in a data sheet of the main part or an auxiliary document of the part vendor. The component information DB 101 also stores a reference circuit described in a data sheet of the component, and a component table indicating the components constituting the reference circuit, as the component specifications.

  When there is a reference circuit for the main part (step S405: Yes), the standard circuit reading unit 105 reads the reference circuit and the component table of the reference circuit from the part information DB 101. Further, the standard circuit reading unit 105 requests the standard component determination unit 106 to determine whether or not the component shown in the read component table is a standard component. In response to the request from the standard circuit reading unit 105, the standard part determination unit 106 determines whether or not the part shown in the component parts table is a standard part by the same process as in step S402 (step S406). The determination result is output to the standard circuit reading unit 105.

  When the determination result indicates that all the parts shown in the component parts table are standard parts (step S406: Yes), the standard circuit reading unit 105 displays the read reference circuit and the component parts table on the display unit 108. (Step S407).

  When the determination result indicates that some or all of the parts shown in the component parts table are not standard parts (step S406: No), the standard circuit reading unit 105 assigns an error attribute to the part determined not to be a standard part. (Step S408), the process proceeds to step S407.

  If there is no reference circuit for the main component shown in the main component list (step S405: No), the standard circuit reading unit 105 displays on the display unit 108 that there is no standard circuit (step S409). In this case, the designer needs to obtain a standard circuit for the main part by means not designed according to the present invention, such as designing by himself / herself.

  Next, the operation at the time of standard part determination in steps S402 and S406 will be described with reference to the flowchart shown in FIG.

  When it is requested to determine whether or not the part shown in the component parts table is a standard part, the standard part determination unit 106 reads the part rank of the part from the part information DB 101. Specifically, the standard component determination unit 106 searches the component information DB 101 for a component with the same basic information using, as a key, basic information that can uniquely identify the component, such as the manufacturer's model number of the component and a unique model number within the department. Then, the component rank of the component having the same basic information is read out. Then, the standard part determination unit 106 determines whether or not the part shown in the component part table is a standard part based on the read part rank (step S501). If a part whose reference information matches the part shown in the component parts table is not searched from the part information DB 101, the standard part determination unit 106 sets the part rank of the part shown in the component part table as the part rank. It is assumed that the parts rank that prohibits the use of is set.

  If the part rank of the part shown in the component parts list is a part rank indicating that the use of the part is permitted (step S501: Yes), the standard part determination unit 106 determines that the part is a standard part. Determination is made (step S502).

  If the part rank of the part shown in the component parts table is a part rank that prohibits the use of the part (step S501: No), the standard part determination unit 106 enters the part information DB 101 of the part. The presence / absence of registration record is determined (step S503).

  As described above, the component information DB 101 stores the component rank and the reason why the component rank is set in addition to the component specifications. Here, for various reasons, a part that was a standard part may be removed from the standard part. For example, there is a case where a failure has occurred due to the part, or a case where the manufacture of the part is finished and replaced with a successor part. In this case, the part rank of the part is changed from recommended use or use permission to use prohibition, so that the part deviates from the standard part. As described above, the parts information DB 101 stores not only the current standard parts but also parts that were previously standard parts but are not standard parts now. Also, usually, when a failure caused by a part occurs, or when the manufacture of the part is terminated and replaced by a successor part, the replacement of that part, such as the successor part, is replaced. The replacement part is stored in the part information DB 101 as a standard part.

  When there is a record of registration in the component information DB 101 of the component shown in the component table (step S503: Yes), that is, when the component has been registered as a standard component before, the standard component determination unit 106 The reason why the part is out of the standard part is acquired from the part information DB 101 (step S504).

  Next, the standard part determination unit 106 uses the part because the acquired reason (the part shown in the component parts table is out of the standard part) is a specific reason (for example, due to the occurrence of a defect due to the part). Is forbidden) or for another reason (for example, because the manufacture of the part has been completed and replaced with a successor part) (step S505).

  When the reason why the part shown in the component parts table is not the standard part is not a specific reason (step S505: No), the standard part determination unit 106 selects from the standard parts stored in the part information DB 101. A substitute part that is a substitute for the part is specified, and substitute part information indicating the substitute part is acquired from the part information DB 101 (step S506), and is indicated in the part indicated in the substitute part information, that is, in the component parts table. The substitute part of the part to be determined is determined as the standard part (step S507). In this case, the standard circuit readout unit 105 replaces the part with a substitute part and causes the display unit 108 to display the part.

  When the reason why the part shown in the component parts table is out of the standard part is the specific reason (step S505: Yes), the standard part determination unit 106 sets the substitute part information indicating the substitute part of the part as the part information. After obtaining from the DB 101 (step S506), it is determined whether or not the part is a main part (step S508).

  If the part shown in the component parts table is not the main part (step S508: No), the standard part determination unit 106 proceeds to the process of step S507.

  If the part shown in the component parts table is a main part (step S508: Yes), the standard part determination unit 106 determines that the part is not a standard part. In addition, the standard part determination unit 106 outputs the substitute part information indicating the substitute part of the part to the standard circuit reading unit 105. Since it is determined that the part is not a standard part, the standard circuit reading unit 105 gives an error attribute to the part and causes the display unit 108 to display the standard circuit or the reference circuit and its component parts table. In addition, the standard circuit reading unit 105 displays on the display unit 108 that the component indicated in the replacement component information is recommended as a replacement for the component having the error attribute.

  As described above, when the part shown in the component parts table is a part deviated from the standard part, if the part is not a main part, the standard part determination unit 106 determines the substitute part for the part as the standard part. On the other hand, if the part is a main part, it is determined that the part is not a standard part, and an alternative part is recommended. This is because the main parts are highly likely to greatly affect the specifications of the apparatus, and therefore it is better to leave the decision as to whether or not to use alternative parts to the designer.

  If there is no record of registration of the parts shown in the component parts table in the part information DB 101 (step S503: No), the standard part determination unit 106 refers to the part information DB 101 and determines whether there is a substitute part for the part. (Step S510).

  If there is a substitute part for the part shown in the component parts table (step S510: Yes), the standard part determination unit 106 proceeds to the process of step S506.

  When there is no substitute part for the part shown in the component parts table (step S510: No), the standard part determination unit 106 determines that the part is not a standard part (step S511).

  Next, the operation at the time of standard circuit registration will be described with reference to the flowchart shown in FIG.

  When the circuit diagram of the circuit block and the fact that the circuit block is registered as the standard circuit are input, the standard circuit registration unit 110 receives the circuit block circuit diagram, the registration request as the standard circuit of the circuit block, Is output to the control unit 107. In response to the registration request for the circuit block, the standard part determination unit 106 determines whether or not all the parts constituting the circuit block are standard parts (step S601).

  When all the parts constituting the circuit block are standard parts (step S601: Yes), the standard part determination unit 106 determines whether or not the circuit block has been registered in the standard circuit DB 102 (step S602).

  When there is a record of registering the circuit block in the standard circuit DB 102 (step S602: Yes), the standard component determination unit 106 additionally registers the circuit block in the standard circuit DB 102 (step S603).

  If there is no record of registration of the circuit block in the standard circuit DB 102 (step S602: No), the standard component determination unit 106 newly registers the circuit block in the standard circuit DB 102 (step S604).

  If all the parts constituting the circuit block are not standard parts (step S601: No), the standard part determination unit 106 does not register the circuit block in the standard circuit DB 102 and uses a part that is not a standard part. Is displayed on the display unit 108, and a warning is given to the designer (step S605).

  Next, a specific operation example of the component selection support device 10 of the present embodiment will be described. In the following description, it is assumed that the component selection support apparatus 10 is configured to be divided into a server side and a client side as shown in FIG.

  First, description will be given of the operation when the specification information is input by the designer and the parts selection support apparatus 10 notifies the designer of the standard circuit and the component parts list.

  When the input of the specification information is input, the display unit 108 displays a dialog box shown in FIG. In the dialog box shown in FIG. 7, information defining the position of the device, such as the name of the development device, device type, usage environment, diversion source device, diversion source function, can be input. Furthermore, in the dialog box shown in FIG. 7, a functional block diagram and a power system diagram can be selected.

  FIG. 8 is a diagram illustrating an example of a functional block diagram.

  A CPU 801, a chip set 802, a memory 803, a USB 804, a sound 805, a hard disk 806, and a DVD-ROM 807 shown in FIG. 8 are circuit blocks. For example, the CPU 801 includes a CPU and subordinate components for causing the CPU to function. FIG. 8 shows a functional block diagram including these circuit blocks.

  FIG. 9 is a diagram illustrating an example of a power supply system diagram. In FIG. 9, the same components as those in FIG. 8 are denoted by the same reference numerals.

  In FIG. 9, the output voltage (12 V) of the regulator 901 is supplied to the regulators 902 to 904, the hard disk 806, and the DVD-ROM 807. Further, the output voltage (1.2 V) of the regulator 902 is supplied to the CPU 801 and the chip set 802. The output voltage (1.8 V) of the regulator 903 is supplied to the memory 803. Further, the output voltage (5 V) of the regulator 904 is supplied to the USB 804 and the hard disk 806.

  After inputting the specification information, the designer uploads the specification information to the server side.

  When the specification information is uploaded from the client side, the specification analysis unit 104 specifies the main parts from the functional block diagram shown in the specification information and the power system diagram, and the main parts list showing the specified main parts Is output to the control unit 107.

  The standard circuit reading unit 105 inquires of the standard circuit DB 102 about the presence or absence of a standard circuit for each main component shown in the main component list. When the standard circuit of the main part is stored in the standard circuit DB 102, the standard circuit reading unit 105 reads the standard circuit and the component parts table of the standard circuit from the standard circuit DB 102.

  Further, the standard circuit reading unit 105 requests the standard component determination unit 106 to determine whether or not all the components shown in the read component table are standard components. In response to the request, the standard part determination unit 106 determines whether or not the part shown in the component table is a standard part, and outputs the determination result to the standard circuit reading unit 105. Here, it is assumed that all the parts shown in the component parts table are standard parts.

  Since all the parts shown in the component parts table are standard parts, the standard circuit reading unit 105 transmits the read standard circuit and information indicating the component parts table to the display unit 108 and the parts table creation support unit 109. .

  As shown in FIG. 10, the display unit 108 displays a standard circuit 1001, a message 1002 indicating that the standard circuit has been read, a menu bar 1004, and the like. The message 1002 indicating that the standard circuit has been read out includes an OK button 1003. When a message indicating that the OK button 1003 has been pressed is input, the message 1002 indicating that the standard circuit has been read disappears.

  Next, as shown in FIG. 11, when “Tool (T)”-“Output BOM” (B) is input from the menu bar 1004, the BOM creation support unit 109 Create

  Next, the operation at the time of standard circuit registration will be described.

  When the standard circuit registration unit 110 is input to display a circuit diagram, the standard circuit registration unit 110 displays the circuit diagram on the display unit 108. Further, when an instruction to select a circuit block to be registered as a standard circuit is input, the standard circuit registration unit 110 hatches the selected circuit block and displays it on the display unit 108 as shown in FIG. Thus, the designer is notified that the circuit block is selected.

  Further, as shown in FIG. 13, when the standard circuit registration unit 110 receives an instruction to select “Tool (T)” — “Register standard circuit (R)” from the menu bar 1004, the selected circuit is selected. Upload the block and its component block table to the server side.

  When the circuit block and the component parts table of the circuit block are uploaded from the client side, the standard part determination unit 106 determines whether or not all the parts shown in the component part table are standard parts. Here, it is assumed that all the parts shown in the component parts table are standard parts. The standard component determination unit 106 stores the circuit block and the component table uploaded from the client side in the standard circuit DB 102. Further, as shown in FIG. 14, the standard component determination unit 106 causes the display unit 108 to display that the registration of the standard circuit has been completed.

  As described above, according to the present embodiment, when the specification information indicating the main components of the electrical circuit to be designed determined according to the required specifications is input, the component selection support apparatus 10 receives various specifications from the standard circuit DB 122. The standard circuit including the main parts indicated in the original information and the component parts table of the standard circuit are read out, whether or not the parts shown in the component parts table are standard parts, and the result of the determination is standard The designer is notified together with the circuit and the component list of the standard circuit.

  Therefore, the designer is notified of the standard circuit for causing the main parts of the electric circuit to function and the parts constituting the standard circuit only by inputting the specification information of the electric circuit to be designed. Since it is also notified whether or not the part is a standard part, it is possible to reduce the labor of selecting the part by the designer.
