Abstract:
A method of operating a device, the device comprising circuitry having an input responsive to a first timing signal and producing a valid output to clocked output circuitry after a first delay, said clocked output circuitry having a clock node, and a clock delay circuit responsive to said first timing signal for providing after a second delay, a second timing signal to said clock node of said clocked output circuitry, the method comprising:repeatedly applying said first timing signal followed by an external timing signal, wherein said external timing signal is applied via a delay-producing first path to said clock node; monitoring an output of said clocked output circuitry; varying the delay produced by said delay-producing first path to vary the delay of application of said external timing signal with respect to said first timing signal; and in response to a desired output of said clocked output circuitry, modifying said second delay.
