    摘要: The invention refers to a method for accessing an passenger transportation device control means comprising several separated printed circuit boards (PCB), whereby each of these PCBs comprises a unique identifier (ID), and in which method the passenger transportation device control means comprise a matching table which is used by the passenger transportation device control means to perform a matching test to check the identifier of at least two of the PCBs and to put the passenger transportation device control means into normal operation only if their IDs match the IDs of the matching table. A service technician connects via a key to the passenger transportation device control means, which key enables the service technician to set the passenger transportation device control means into a fault finding mode, in which fault finding mode the passenger transportation device control means are initiated to skip the matching test before getting into operation, whereby the fault finding mode is terminated at the latest when the service technician terminates the key-based connection with the passenger transportation device control means.

    摘要: Disclosed herein is a test circuit for a device under test. The test circuit includes a test data source and a test data target. A debug chain is coupled between the test data source and test data target, and operates in either a clock debug mode or a test mode. The debug chain, when in the test mode, is deactivated. The debug chain, when in the clock debug mode, receives the test pattern data from the test data source and stores the test pattern data, generates a clock debug signature from the stored test pattern data while clocked by a test clock, and outputs the clock debug signature to the test data target, the clock debug signature indicative of whether the test clock is operating properly.

    摘要: The present invention provides a technology for comprehensive verification of the safety of the design of functions, on the basis of a safety analysis result. The disclosed vehicle control system verification device is equipped with a storage device that stores programs for verifying the safety of the logical architecture of a vehicle control system, and a processor that reads the programs from the storage device and verifies the safety of the logical architecture. On the basis of safety analysis result information that is supplied, the processor executes a process for verifying whether the logical architecture has logical functions corresponding to the safety analysis result.

    摘要: A hardware model of a memory comprises: first circuitry configured to supply a memory status value for the memory which is changed upon a full-memory erase operation; second circuitry configured to supply a sector status value for each memory sector of the memory which is changed to a value equal to the memory status value when a write operation is performed on the each memory sector of the memory; and third circuitry configured to supply, when a read operation is performed on a memory sector of the memory, a value stored in the memory sector as output of the read operation if the sector status value for the memory sector is equal to the memory status value or a predefined value as the output of the read operation in other situations.
