Abstract
A method and apparatus for simulated error injection for processor deconfiguration design verification is provided. A simulated error condition request is received from a user through software, such as the operating system executing in the multiprocessor data processing system. In response to the requested simulated error condition, an error condition is injected into a processor of the multiprocessor data processing system via instruction execution. In response to the detection of the error condition and execution of error-path code, a processor is deconfigured. The error condition may be injected by executing an instruction to set an error condition bit in an error condition register.
