Patent attributes
An electronic device having first circuitry operating in a first clock environment and second circuitry operating in a second clock environment, the first circuitry being arranged to generate a soft reset signal for resetting the second circuitry, the integrated circuit further including: a soft reset hold circuit clocked in the first clock environment connected to receive the soft reset signal and to generate an output reset signal in an asserted state; and a synchronizer clocked in the second clock environment connected to receive the output reset signal and to generate a retimed reset signal in an asserted state after a predetermined period, wherein the retimed reset signal is fed back to the soft reset hold circuit to cause the output reset signal to adopt a deasserted state at the end of said predetermined period.
