  • Publication number: 20240338207
    Abstract: A system obtains information on parts embedded in a final product across a range of companies, comprising: a product life cycle management system, used by a manufacturing company manufacturing a final product by embedding parts operated by software, for managing information on the final product and the parts and the range of disclosure of data relating to software contracted between the manufacturing company and a company that provides the parts to the manufacturing company; and a product life cycle management system used by the providing company for managing the range of disclosure and software-related data that is data relating to the software. One product life cycle management system requests a second system to disclose the software-related data within the range of disclosure, and the second system transmits the software-related data to the product life cycle management system if the requested software-related data falls within the range of disclosure.

  • Publication number: 20240078119
    Abstract: Function definition information is prepared in a system. The function definition information is information representing a correspondence relationship among a software-based function, a vehicle ID of a vehicle, a hardware configuration for implementing a function, and a software configuration for implementing a function. The system performs a preliminary determination including a determination of a relationship between one or a plurality of user-desired functions constituting a user-desired function group of a user and a hardware configuration of a target vehicle based on the function definition information. For each of the one or more functions specified in the preliminary determination, in order to implement the function in the target vehicle, the system develops a software configuration corresponding to the function in a hardware configuration corresponding to the function in the target vehicle.

  • Publication number: 20130239098
    Abstract: In checking a model of software, there is an approach of transforming a source code of software into a checking code in order to reduce a cost required to describe the checking code by an input language of a model checker. Since a user may select only a single transformation method, there are problems in that an abstraction-level change is difficult, a rule modification cost for following up a design and a change of the source code is high, and a rule modification cost for checking using another checking tool is high. In the present invention, when the source code is transformed into the checking code, a unit that selects a plurality of transformation rules is provided to allow the user to easily change an abstraction level. Further, the plurality of transformation rules include a transformation rule of transforming the source code into an intermediate format, a transformation rule of abstracting the intermediate format, and a transformation rule of transforming the intermediate format into the checking code.

  • Publication number: 20120317442
    Abstract: The redundancy that is effected by preparing a plurality of units of hardware of an identical configuration results in high costs, complicating the application of same to inexpensive products. The present invention detects a fault in a function that is provided via hardware upon an apparatus having a variety of components, such as a CPU, capable of changing content to be processed at the application level, and an FPGA, capable of changing the content to be processed. When a fault is thus detected, the invention uses configuration information of an apparatus either within the apparatus or within apparatuses upon the network to select an apparatus capable of serving as a substitute, selects software required to implement the function, carries out procedures for facilitating the use of the software upon the substitute hardware (i.e., downloading the software, loading the software into a memory region accessible to the hardware), and carries out the processing in substitution.

  • Patent number: 7818620
    Abstract: A CPU forced stop signal is used as means for stopping execution of a program executed on a ROM by a CPU of a target system. A time required for stopping the CPU from the issuance of the CPU forced stop signal between an ICE device and the CPU is considered and set, and a CPU forced stop signal issuance position which is prior to a stop target position is determined. Based on a real-time tracing function of the CPU, at an issuance position and timing of the CPU forced stop signal on the execution of the program, the CPU forced stop signal is issued, the CPU is stopped, and the event is acquired. By this means, an arbitrary number of events of the program can be acquired regardless of the number of breakpoint registers.
