The invention relates to the technical field of integrated circuits, and provides a
chip programmable power domain
system and a
chip programmable power domain method, through
collaborative design of a new programmable power domain
system structure, a configuration carrier is converted from
physical level / logic
signal control to power network physical
connection control, a PMU is directly controlled to carry out physical on-off on a power domain, and the power domain can be directly switched on and off. A cooperative
locking mechanism of an OTP fuse and a safety
arbiter is introduced, so that real zero-power-consumption closing and permanent locking are realized; a fuse array is divided into two independent functional domains, namely a configuration data area and a locking status bit, and a state judgment and
access control logic of a security
arbiter is embedded in a reading process, so that separated management and control of configuration permission and configuration storage are realized; and a general
application layer interface is used as a post-configuration channel to realize a high-level security protocol, so that the security and the
mass production convenience are improved, and the final function of the
chip can be flexibly and reliably determined with low
power consumption in the later period of production.
