US 2014/0207994 A1 · CIRCUIT ARRANGEMENT FOR UNIVERSAL CONNECTION OF A BUS PARTICIPANT TO AT LEAST ONE BUS

Abstract

A circuit arrangement for connecting a bus participant to at least one bus, having an interface for connecting the bus participant to the circuit arrangement, a first bus input, and a first bus output between which the bus participant is switchable via the interface. The circuit arrangement includes a second bus input and output for connecting the bus to the circuit arrangement in a ring topology in such a way that the first bus output is connected at least indirectly to the second bus input and the second bus output is connected at least indirectly to the first bus input via the bus. The bus in the circuit arrangement can be separated to obtain a line topology and can be configured as bus-terminating at one of the bus inputs or bus outputs. A system for the functional testing of bus participants on a bus in a simulation environment is provided.

A system for the functional testing of bus participants on a bus in a simulation environment, the system comprising:

a plurality of circuit arrangements;
and
a bus, wherein the bus participants are each connectable to the bus via one of the circuit arrangements;
and
a simulator unit for simulating control signals on the bus,
wherein each of the circuit arrangements has a first and a second bus input and a first and a second bus output and the bus connects the circuit arrangements in a ring topology such that each first bus output of one of the circuit arrangements is connectable either to the first bus input of the next circuit arrangement or to the second bus input of its own circuit arrangement,
wherein each second bus output of one of the circuit arrangements is connectable either to the second bus input of the next circuit arrangement or to the first bus input of its own circuit arrangement, and
wherein the bus in each of the circuit arrangements is separated to obtain a line topology and each circuit arrangement is configured as bus-terminating at one of the bus inputs or bus outputs.
