1. A method for fault testing a system, the method comprising:
receiving a bus response to a bus request transmitted by a bus master over a network circuit, wherein the bus response is transmitted by a bus slave and the bus request and the bus response are associated with a bus transaction over the network circuit;
selecting a delay time to delay transmission of the bus response to fault test the system, the system comprising the bus master, the bus slave, and the network circuit;
delaying the bus response by the delay time;
transmitting the delayed bus response to the bus master; and
determining whether the fault test fails based on the delayed bus response.
