Abstract: An electronic device having first circuitry (2) operating in a first clock environment (clk1) and second circuitry (33) operating in a second clock environment (clk2) the first circuitry (2) being arranged to generate a soft reset signal for resetting the second circuitry (33) the integrated circuit (11) further comprising: a soft reset hold circuit (3) clocked in the first clock environment (clk1) connected to receive the soft reset signal and to generate an output reset signal in an asserted state; and a synchroniser (5) clocked in the second clock environment (clk2) connected to receive the output reset signal and to generate a retimed reset signal in an asserted state after 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.
