An appropriate test environment is selected while preventing test cases from being detained therein. A test environment determination device includes: an element selection unit that selects one or more test targets and one or more test environments for executing a test case based on target requirements described for specifications of an electronic control unit, which is a test target, and environment requirements described for specifications of a test environment for simulating an external environment of the test target; an environment operation information acquisition unit that acquires operation information on the test environments; and an environment selection unit that selects a combination of the selected test target and the selected test environment based on the acquired operation information.

Test environment determination device and test environment determination method

The invention provides a technology for suppressing a delay in communication between a plurality of cores that perform parallel processing. In the invention, an ECUof a vehicle control systemincludes a plurality of coresand a shared memory. When transmitting data in the inter-core communication, a transmission side core-writes a counter value updated according to the data and a writing order to a buffer unitwhich is determined by a counter value managed for each communication system, which is stored in each of the plurality of buffer unitsprovided in the shared memory. When receiving data in the inter-core communication, a reception side core-reads data from the buffer unitin which the latest data for each communication system is stored, which is determined by the counter value stored in each of the plurality of buffer units

Disclosed subject matter is related to project reusability including method and system for identifying reusable project components for building a new project. The method comprises extracting current requirement of the new project from one or more data sources, using NLP and detect pre-existing requirements associated with pre-existing projects, similar to the current requirement by performing semantic analysis of the current requirement and the pre-existing requirements using a predefined machine learning technique such as Latent Semantic Analysis (LSA) technique. Further, a similarity score is determined for each of the one or more pre-existing requirements based on degree of similarity between the current requirement and the pre-existing requirements. Finally, the reusability detecting system retrieves project components associated with one of the pre-existing requirements based on the similarity score that are the reusable project components for building the new project, thereby reducing time, cost and resources required for developing the new project.
