Abstract: Aspects of the present disclosure provide techniques and apparatus for distributed built-in self-test. An example method of testing circuitry includes testing, in a first occasion, a first electrical circuit, having a first component, using at least a second component of a second electrical circuit; and testing, in a second occasion, the second electrical circuit using at least the first component of the first electrical circuit.

Abstract: Certain aspects of the present disclosure provide methods and apparatus for level shifting an input signal ranging between certain voltage levels to generate an output signal ranging between other voltage levels with low power, high speed, and immunity to noise. One example level-shifting circuit generally includes a node for receiving an input signal ranging between a first voltage level and a second voltage level, a first circuit path coupled to the node and configured to level shift the input signal to generate an output signal ranging between a third voltage level and a fourth voltage level, a pulse generator coupled to the node and configured to generate a pulse based on a transition in the input signal between the first and second voltage levels, and a second circuit path connected in parallel with the first path and configured to temporarily short the first path based on the generated pulse.
