摘要:
An Automated Dynamic low voltage monitoring (LVM) based Low-Power (ADLLP) debug capability for a system-on-chip (SoC) as well as the open/closed-chassis platform for faster TTM (Time to Market) of the final platform or system. ADLLP Debug is achieved by detection of the probe connection between a target system (e.g., SoC) and debug host system. A user can dynamically override the power, clocks and LVM for intellectual property (IP) blocks not part of the debug trace by instructing a Power Management Controller (PMC) via the Inter Processor Communication (IPC) mailbox (or any other suitable mailbox driver) to set the registers in a Target Firmware (TFW) based on the probe and debug use-case.
