System-in-loop testing for adas socs

A system comprising:

• multiple destination components;
• and
• interface circuitry including a set of virtual channel ports, and a table mapping each of the virtual channel ports, of the set of virtual channel ports, to at least one of the multiple destination components, the interface circuitry configured to:
• receive an update packet via a first virtual channel port of the set of virtual channel ports, in which the first virtual channel port is associated with a first destination component of the multiple destination components in a current version of the table;
• wherein the first destination component is configured to:
• receive the update packet from the interface circuitry, and parse the update packet to determine that, in the current version of the table, a first value of the update packet maps to a particular destination component, of the multiple destination components, that is associated with a particular virtual channel port, of the set of virtual channel ports, and a second value of the update packet represents a new destination component, of the multiple destination components, to be associated with the particular virtual channel port;
• and
• cause the interface circuitry to modify the current version of the table to generate an updated version of the table in which the second value is written in place of the first value to associate the particular virtual channel port with the new destination component, such that the system is configured to route a subsequent packet received via the particular virtual channel port to the new destination component associated with the second value of the update packet.
