Abstract
Systems, methods, and other embodiments described herein relate to improving the testing of electronic devices using adaptable interfaces. In one embodiment, a method includes receiving a set of virtual electronic control units, receiving a set of interface devices connected to test devices, simulating wire harnesses where each wire harness contains a subset of virtual electronic control units and a subset of interface devices, both of which are configured to communicate therein based on a multicast protocol, and injecting a fault in a target wire harness affecting a test device connected to the subset of interface devices associated with the target wire harness in accordance with a multicast group assignment.
Claims20
An interface system, comprising:
- one or more processors;
- and
- a memory communicably coupled to the one or more processors and storing a control module, including instructions that, when executed by the one or more processors, cause the one or more processors to:
- receive a set of virtual electronic control units;
- receive a set of interface devices connected to test devices;
- simulate wire harnesses where each wire harness contains a subset of virtual electronic control units and a subset of interface devices, both of which are configured to communicate therein based on a multicast protocol;
- and
- inject a fault in a target wire harness affecting a test device connected to the subset of interface devices associated with the target wire harness in accordance with a multicast group assignment.
A non-transitory computer-readable medium including instructions that, when executed by one or more processors, cause the one or more processors to:
- receive a set of virtual electronic control units;
- receive a set of interface devices connected to test devices;
- simulate wire harnesses where each wire harness contains a subset of virtual electronic control units and a subset of interface devices, both of which are configured to communicate therein based on a multicast protocol;
- and
- inject a fault in a target wire harness affecting a test device connected to the subset of interface devices associated with the target wire harness in accordance with a multicast group assignment.
