Abstract
Embodiments described herein may include apparatus, systems, techniques, and/or processes that are directed to performing testing of a device while a system is operational. A device may include computing circuitry and host connectivity registers. Host connectivity registers contain configuration and memory mapping data programmed by system software upon power up of the device and computing system. The data contained in host connectivity registers should be always maintained while the computing system is operational. Scan test circuitry may be implemented, providing the ability to test the device while the system is operational. Preservation circuitry preserves or maintains the data stored in host connectivity registers allowing in-operation testing of the device, ensuring the device the ability to return to full operation at the end of in-operation testing without requiring system software to reprogram the host connectivity registers. By using scan-sealing methods and/or preserving the data in host connectivity registers during in-operation testing, performance and user experience are not degraded.
