Abstract:
1. An apparatus including a mixed signal integrated circuit with self test capability, comprising: a plurality of power electrodes to convey DC power at one or more source voltages; a plurality of input signal electrodes to convey a plurality of input signals including one or more digital input signals and one or more analog input signals; a plurality of output signal electrodes to convey a plurality of output signals including one or more digital output signals and one or more analog output signals; digital circuitry coupled, at least in part, to said pluralities of power, input signal and output signal electrodes, and responsive, during a plurality of substantially mutually exclusive time intervals, to at least a portion of said plurality of input signals and one or more test signals by selectively processing said at least a portion of said plurality of input signals and said one or more test signals, and selectively providing one or more control signals and at least a portion of said plurality of output signals including one or more result signals related to said one or more test signals; and analog circuitry coupled, at least in part, to said pluralities of power, input signal and output signal electrodes, and to at least a portion of said digital circuitry, and responsive to at least another portion of said plurality of input signals and said one or more control signals by selectively processing said at least another portion of said plurality of input signals and said one or more control signals and selectively providing at least another portion of said plurality of output signals and said one or more test signals.
