An integrated circuit (IC) includes one or more testable voltage decoupling (DCAP) cells. Each of the testable DCAP cells includes (i) one or more decoupling capacitors connected between supply rails of the IC, and (ii) a decoupling-test active logic (DTAL) circuit, which has a normal input-output response and is configured to deviate from the normal input-output response in response to a fault in the DCAP cell.

An electronic device includes a first integrated circuit (IC) die and a second IC die. The first IC die includes a first set of contact pads arranged in a first geometrical pattern on a first surface of the first IC die, the second IC die includes a second set of the contact pads that are arranged, on a second surface of the second IC die, in a second geometrical pattern that is a mirror image of the first geometrical pattern. The second surface of the second IC die is facing the first surface of the first IC die, and the contact pads of the first and second sets are aligned with one another and mounted on one another.
