Abstract
The system and method of using a debug interface recorder and replay unit for debugging and testing devices of interest such as integrated circuits by using a debug interface buffer controller to receive, record, and replay sequences of instructions to the integrated circuit. This is particularly useful for deployed devices that are difficult or dangerous to access. This is also beneficial for devices that cannot be reached (e.g., after launch). By recording sequences and storing them for later use, and by communicating commands and configuration settings to a device, system maintenance and troubleshooting is accomplished saving valuable time and money without requiring physical access to the device of interest.
