  • Publication number: 20240289263
    Abstract: An analysis device specifies a cause when a test of test target software fails in a test environment that is an environment for executing a test. In the test, execution of test target software and confirmation of an execution result are executed by a test script without human intervention. Test data is data read into the test target software and the test script when the test is executed. The analysis device includes: a score calculation unit that calculates a failure cause score for each of test target software, test data, a test script, and a test environment based on the presence or absence of a change; and an estimation unit that estimates, based on a failure cause score, whether the test has failed due to test target software, test data, a test script, or a test environment.

  • Patent number: 11307829
    Abstract: In the present invention, a map information table is displayed as a list on a display screen. The map information table associates a reference name field representing each of the plurality of device ports with a set value field for each device port. It is determined whether a set value has been written on the set value field for each of the device ports regarding a first program in a first programming language. Writing of a set value on the set value field is prohibited regarding a second program in a second programming language, which is different from the first programming language, for a device port for which it is determined that a set value has been written on the set value field regarding a first program in the first programming language.

  • Patent number: 9239014
    Abstract: The invention relates to an automotive control device and a period measurement method for measuring a period of a pulse signal input from outside. The automotive control device processes the pulse signal input from outside using an analog filter in parallel with a digital filter. When a difference between a measured value of a period of an output signal of analog filter and a measured value of a period of an output signal of digital filter is less than a threshold value, the automotive control device selects the measured value of the period of the output signal of analog filter as the period of the pulse signal. Meanwhile, when the difference between the measured values is greater than the threshold value, the automotive control device selects the measured value of the period of the output signal of digital filter as the period of the pulse signal.
