US 12,001,850 B2 · Method for determining functional safety of reset, and electronic device for executing same

Abstract

In order to determine whether a reset function of an electronic device is safe, the states of a first checker and a second checker are toggled to preset states when a reset root is received from an external device. When a release of a local reset is received, whether the local reset was normally released is determined on the basis of a system clock. When the local reset is not normally released, the state of the second checker is toggled, and when the final local reset among the local resets is normally released, the state of the first checker is toggled. The release states of the local resets are monitored on the basis of the state of the first checker and the state of the second checker.

Dependent claims

A method for monitoring a reset release sequence of a system performed by an electronic device, the method comprising:

receiving a reset root from an external device;
toggling states of a first checker and a second checker to preset states when the reset root is received;
determining, on the basis of a clock of the system, whether the local reset is normally released when a release of at least one local reset is received;
toggling the state of the second checker when the at least one local reset is not normally released;
toggling the state of the first checker when a final local reset of the at least one local reset is normally released;
and
outputting the state of the first checker and the state of the second checker,
wherein a release state of the local reset is monitored on the basis of the state of the first checker and the state of the second checker.

An electronic device for monitoring a reset release sequence of a system, the electronic device comprising:

a memory in which a program for monitoring a reset release sequence is recorded;
and
a processor configured to perform the program,
wherein the program is configured to perform:
an operation of receiving a reset root from an external device;
an operation of toggling states of a first checker and a second checker to preset states when the reset root is received;
an operation of determining, on the basis of a clock of the system, whether the local reset is normally released when a release of at least one local reset is received;
an operation of toggling the state of the second checker when the at least one local reset is not normally released;
an operation of toggling the state of the first checker when a final local reset of the at least one local reset is normally released;
and
an operation of outputting the state of the first checker and the state of the second checker, and
a release state of the local reset is monitored on the basis of the state of the first checker and the state of the second checker.
