Description

  The present invention relates to a software development support system, a development support method, and a program for supporting automatic creation of a program in accordance with a software design drawing, in particular, an erroneous definition of the same register variable used on the design drawing, Concerning reusability check.

  As a software development support system that creates software design drawings on a GUI basis and supports automatic creation of programs according to the design drawings, specifications and design drawings are described using UML diagrams. There is a support system that supports software development such as “creation”, “analysis”, “design”, “implementation”, and “maintenance” (for example, see Non-Patent Document 1).

  On the other hand, in embedded software development, a block diagram is created as a design drawing related to computation. Further, as a design drawing regarding the order of processing, a diagram like a flowchart may be used as a design drawing as shown in FIG. For example, when an embedded device to be developed performs addition and multiplication, blocks representing addition and multiplication are arranged from input to output, and the operation order is expressed by connecting the blocks with lines. When implementing based on this design drawing, a program is created based on the created block diagram, and this program is compiled using a dedicated compiler and incorporated into an actual machine to enable an operation test.

  Such a software development support system holds information necessary for automatically creating a program. For example, variable information (type, scope, variable name, storage class, used UI (user interface) information, etc.), function information (type, scope, function variable name, storage class, used UI information, function use) And the like, and the order in which the program is automatically created from the control information on the program and the representation of the design drawing (program flow information).

  As an example, FIG. 14 and FIG. 15 are shown. In the case of FIG. 14, the process A and B constituting the design drawing X are connected before and after (input side and output side), and variables reg1, reg2, etc. are allocated to the lines, and the software development support system Has variable information and program order information (program flow information) in addition to the UI information of the design drawing X. The variable name is displayed on the connection.

  In the case of FIG. 15, the order of the processes A and B constituting the design drawing Y is connected by lines, and input / output variables and the like are assigned to them, and the software development support system uses the UI of the design drawing Y. In addition to information, it has attribute information such as variables used in processing, variable information, and program order information (program flow information).

  Among programs automatically created by such software development support systems, there are cases in which blueprints and programs using register variables that use registers as read / write areas are used as means for speeding up operations. is there. Here, a register is a storage element in a CPU (Central Processing Unit) that can be read and written at high speed, and its contents can be freely referred to and updated from within a program. In design drawings and programs that use register variables, data can be written to and read from CPU registers by declaring register variables.

Meiden Times September / October 2006 No. 310 No. 5 “Specification creation support function in the software development comprehensive support system”

  When reading / writing data to / from the register from the program, care must be taken to prevent data from being overwritten on the register in use. If data is overwritten to a register that is in use at a location that is not intended by the software developer, a problem occurs in the developed system.

  In the case of a program in which interrupt processing occurs, there are many cases where data is overwritten on a register in use even when the same register variable is used at the interrupt source and the interrupt destination.

  Also, in embedded systems, etc., the number of registers that can be used by each CPU is limited, so programs may be created by using register variables. In such a situation, overwriting data in the registers in use There are many cases where this occurs.

  In the case of a software development support system that executes simulations or automatically creates programs based on software design drawings, information on variables used in the design drawings (type, scope, variable name, storage class, etc.) ) Is. However, register variables may be reused and may exist across multiple design drawings. In this case, only the software development support system user who described the design drawing knows whether or not the usage of register variables is correct, so the system generally issues an error notification to the usage of register variables. difficult.

  Therefore, in the software development support system, if a program is automatically created without any check, it will result in a program that cannot be expected to execute as intended by the user, and an actual operation test using the automatically created program will be performed. It takes a lot of time for development, such as finding defects in the software, and it becomes a heavy burden on the user of the software development support system.

  In addition, before the software development support system automatically creates a program, in order to identify the location where register variables are used, each variable definition on the design drawing must be checked one by one. It takes a lot of time and becomes a heavy burden on the user of the software development support system.

  An object of the present invention is to provide a software development support system, a development support method, and a program that facilitate the erroneous definition of register variables and the check of reuse in register variable design and automatic program creation.

(Embodiment 1)
FIG. 1 shows a functional configuration diagram of the present embodiment. A software development support system 100 that creates a software design drawing based on a GUI and automatically creates a program based on the design drawing is equipped with a register variable check device 10 composed of computer resources and software using the same. To do.

  The register variable check device 10 includes a register variable definition information acquisition unit 10A and a highlight display unit 10B. The register variable definition information acquisition unit 10A acquires register variable definition information from information (variable information) inside the system, and specifies information specifying which register is assigned to which part on which UI (design drawing). get. The highlighting unit 10B highlights a portion related to the register variable in accordance with highlighting specifications (for example, color, line thickness, line type, etc.) held by the system.

  By installing such a register variable check device 10 in the development support system, the register variable used in the design drawing creation stage or automatically created program and its use location are highlighted, and this register variable is highlighted. For the design drawing and the drawing related to the program, the function configuration is made so that the use position of the register variable can be specified at a glance. This facilitates the user of the system to check whether register variables are overwritten on the same register.

  The function of the register variable checking device 10 will be specifically described. When designing a system in which interrupt processing occurs, even if the same register variable is used at the interrupt source and the interrupt destination, data overwriting to the register in use often occurs. However, even when looking at the design drawings of the interrupt source process and the interrupt destination process, it is difficult to see at a glance which register variables are overwritten from the design drawing.

  The case where the interrupt source design shown in FIG. 2 and the interrupt destination design 2 shown in FIG. 3 are designed will be described. Program flow information corresponding to FIG. 2 and FIG. 3 is shown in FIG. 4 and FIG. 5, and examples of variable information in both figures are shown in FIG.

  When an interrupt occurs at the timing as shown in FIG. 7, reg2 (S2 in FIG. 4) used in the design diagram 1 (interrupt source) is reg2 (FIG. 5) calculated in the middle of the design diagram 2 (interrupt destination). In step S4), reg2 (S2 in FIG. 4) originally calculated in the design diagram 1 (interrupt source) should be used, but it becomes a different value.

  Therefore, as described above, the software development support system can recognize the location where the register variable is used inside the system (variable, information), and therefore, using the highlighting held by the system for each register variable name. (For example, color, line thickness, line type, etc.) are highlighted. As an example, in the example of highlighting by color, the same color (red) is set and displayed in the same register variable reg2 displayed in FIGS.

  FIG. 8 shows a flow of the highlighting function by the register variable checking device 10. Register variable definition information is acquired from information (variable information) inside the system (S10). If there is register variable definition information (S11), its definition number i is initialized to "0" (S12), and the i-th Register variable definition information is acquired (S13), UI information related to the i-th register variable definition information is acquired (S14), and the use ui information of the register variable on the design drawing is determined from the acquired UI information ( In step S15, the use ui information of the determined register variable is highlighted (S16).

  After these processes S13 to S16, it is checked whether or not there is register variable definition information that has not been processed (S17), and if there is, the definition number i is incremented (S18), and this is related to the i-th register variable definition information. Use ui information on the design drawing is highlighted (S13 to S18).

  According to this embodiment, the user of the software development support system can identify at a glance the UI related to the use location on the displayed design drawing, and it is easy to check whether or not the register variable is overwritten. , Check burden is reduced.

  In addition, the system user can use the register variables correctly by checking, thereby obtaining an appropriate program, reducing errors in the program output by the software development support system, and shortening the operation test time. Become.

(Embodiment 2)
In the register variable checking process according to the first embodiment, when the highlighted specification is used for other functions of the software development support system, the part that is not a register variable use part is as if it is a register variable use part. There is a risk of misunderstanding of the user.

  In the present embodiment, the software development support system user can set the highlighting specification for each register variable. For example, the color, line thickness, line type, and the like are set via a UI or via a file.

  FIG. 9 shows a functional configuration diagram of the present embodiment, and the register variable check device 10 is installed in the software development support system. In FIG. 9, as in FIG. 1, the register variable definition information acquisition unit 10 </ b> A acquires register variable definition information from information (variable information) inside the system, and which register is on which UI (design drawing). Whether it is assigned to or not can be acquired. In addition, the highlighting unit 10B performs highlighting according to highlighting specifications (for example, color, line thickness, line type, etc.) held by the system.

  The highlighting specification reading unit 10C newly added in the present embodiment enables reading of the highlighting specification via a UI or a file.

  In order to allow the system user to set the highlight specification, the system uses the defined register variable and the highlight specification set by the system user (eg color, line thickness, line type, etc.). Have an association. If the system user does not set, use the highlighting specification stored in the system.

  FIG. 10 shows a flow of highlighting according to the present embodiment. 8 differs from FIG. 8 in that when the use ui information of the register variable is determined (S15), the highlight specification reading unit 10C acquires the highlight specification associated with the i-th register variable ( In step S20, the use ui information of the determined register variable is displayed in the highlighted display specification acquired in step S20 (S21).

  According to the present embodiment, in addition to the effects of the first embodiment, even when the highlight specification is used for other functions of the software development support system, the system user sets the highlight specification. Since this is possible, highlighting can be made specifically for the location where register variables are used, and the burden on the system user regarding whether or not to overwrite can be reduced.

(Embodiment 3)
In the above embodiments, if there are multiple design drawings, if all the design drawings are not opened and checked, all checks for overwriting will not be completed. The work efficiency may be reduced.

  As described above, a software development support system for creating a software design drawing based on a GUI and automatically creating a program based on the design drawing holds information necessary for automatically creating the program. . For example, variable information (type, scope, variable name, storage class, usage UI information, etc.), function information (type, scope, function variable name, storage class, usage UI information, etc.), program control information and design drawings In what order the program is automatically created from the expression (program flow information).

  In this embodiment, based on these pieces of information, the defined register variables and the design drawings in which the register variables are used are listed, and which register variable is on which design diagram to the software development support system user. Provide information on whether it is used up. At this time, the development support system associates the actual design drawing with the displayed information, and when the listed design drawing information is selected with a mouse or the like, the design drawing is displayed. At this time, in the displayed design drawing, it is displayed at the center of an external output device such as a display so that the use location of the target register variable can be understood. These series of processes may be provided as an auxiliary function in the register variable definition information acquisition unit 10A, or may be provided as a register variable list-up unit separated from the acquisition unit 10A.

  According to the present embodiment, in addition to the effects of the first and second embodiments, when the related design drawing is displayed in a list, only the design drawing 1 (interrupt source) is displayed as shown in FIG. However, it can be seen at a glance that the register variable reg2 is also used in a different design drawing (design drawing 2 (interrupt destination)), and the work efficiency of the check increases.

  In addition, even when there are a large number of blueprints used in the system, there is no need to search for blueprints that are used, the system usage for checking whether register variables are used efficiently and overwriting can be performed. Can be reduced.

(Embodiment 4)
In the above embodiments, when the number of register variables is increased, the number of highlights on the design drawing increases, and the system user misidentifies the register variable to be checked (cannot be overwritten properly) or overwritten. There is a risk that the efficiency of the check work may be reduced.

  In the present embodiment, a mechanism for reducing misrecognition of register variables to be checked by a software development support system user is proposed.

  FIG. 12 shows a functional configuration diagram of the present embodiment, and the register variable check device 10 is installed in the software development support system. In FIG. 12, as in FIG. 9, the register variable definition information acquisition unit 10 </ b> A acquires register variable definition information from information (variable information) inside the system, and which register is on which UI (design drawing). Whether it is assigned to or not can be acquired. In addition, the highlighting unit 10B performs highlighting according to highlighting specifications (for example, color, line thickness, line type, etc.) held by the system. The highlighted specification reading unit 10 </ b> C enables the highlighted specification to be read via a UI or a file.

  The highlighting check unit 10D newly added in the present embodiment checks whether or not highlighting of register variables having the same variable name is performed.

  As in the second embodiment, in the development support system, register variables and highlight specifications (for example, color, line thickness, line type, etc.) are associated with the variables. In addition, the development support system has not only a specification for highlighting the information associated with the register variable, but also information on whether or not the highlighting is newly performed, and the system user does not perform the highlighting. It is possible to set such information. Information on whether or not to perform highlighting is set via a UI or a file. In addition, the development support system has information on whether to perform highlighting by default, and if the system user does not set it, the information that is held by default is used to determine the highlighting process. To do.

  FIG. 13 shows a flow of highlighting according to the present embodiment. The difference between FIG. 10 and FIG. 10 is that when the use ui information of the register variable is determined (S15), the highlight check unit 10D determines whether or not to perform the highlight associated with the i-th register variable. When the information is acquired (S30) and the highlighting is performed (S31), the highlighting specification associated with the i-th register variable is acquired (S20), and the use ui information of the determined register variable is stored in S20. Display with the highlighted display specifications obtained in (S21).

  According to the present embodiment, in addition to the functions and effects of the first to third embodiments, by highlighting only specific register variables, erroneous recognition of register variables that should be checked by the system user can be reduced.

  Note that the present invention can be provided as a program in which some or all of the processing functions of the register variable check method described in each embodiment can be executed by a computer.
