The software debugging system provides a processor that is executing a software process, and the software process has a bug or other failure. A fast-response reporter circuit connects to a low level asset in the processor, such as a reorder buffer, commit buffer, or high speed data path. The fast response reporter circuit is configured to selectively extract data from the low-level asset, and the extracted data is transmitted to an evidence file for review and analysis. In one arrangement, a fast-response sentry circuit also connects to a low-level asset in the processor, and is configured to monitor for a predefined event. When the predefined event occurs, the fast-response sentry circuit causes an action to occur, such as activation of the reporter fast-response circuit.
