    摘要: A multi-node communications system is provided with communications protocol using both static (11, 12, 13, 18) (pre-determined) and dynamic (51, 52, 53 . . . ) (run-time determined) consecutive communication slots is used. The system has a number of distributed communication nodes, each node being arranged for communicating frames of data with the other nodes during both the static (11, 12, 13 . . . ) and the dynamic (51, 52, 53 . . . ) communication slots. Each node includes a synchronized time base 5 made up of consecutive timeslots (11, 12, 13 . . . , 51, 52, 53 . . . ). The timebase 5 has substantially the same error tolerance in each node. For static communication (10), a predetermined number of timeslots (20) are utilized for each static communication slot. For dynamic communication a dynamically allocated number of timeslots (60) are utilized for each dynamic communication slot. In this way both static and dynamic media arbitration is provided within a periodically recurring communication pattern. Communication jitter is well defined and dealt with, and large oscillator drifts are compensated for.

    摘要: A system for testing a logic circuit which has two or more test routine modules. Each module contains a set of instructions which is executable by (a part of) the logic circuit. The set forms a test routine for performing a self-test by the part of the logic circuit. The self-test includes the part of the logic circuit testing itself for faulty behavior, and the part of the logic circuit determining a self-test result of the testing. The system includes a test module which can execute a test application which subjects the logic circuit to a test by performing the self-test on at least a part of the logic circuit by causes the part of the logic circuit to execute a selected test routine, and determining, by the test module, an overall test result at least based on a performed self-tests. The test module includes a control output interface for activates the execution of the a selected test routine. A second test module input interface can receive the self-test result from a selected test routine. At a test module output interface the overall test result may be outputted. The test routine includes instructions for outputting, by the part of the logic circuit, data to a test routine output interface which is not connected to the second test module input interface, for outputting information about the self-test result by the test routines without passing the information through the test module.
