ABSTRACT:
A system and method for detecting accesses to non-existing hardware entities using a simulator environment. When an application running on a simulated target platform issues a transaction that involves accessing a hardware address, wherein the address is within a range of addresses allocated to a simulated hardware block, a set of instructions provided with the simulator are operable to determine if there exists a backing that corresponds to the transaction's address. If there is no backing (i.e., a control status register) associated with the address, an appropriate notification or warning is provided as a response.
