Abstract
In some embodiments, an integrated circuit (IC) chip package, includes a die; and die level diagnostic cell circuitry embedded in the die at a die level diagnostic testing location, wherein the die level diagnostic cell circuitry located at the die level diagnostic testing location incorporates a die level diagnostic stimulus to test a diagnostic trace of the die without requiring a decapsulation of the integrated circuit chip package. In some embodiments, the die level diagnostic cell circuitry is utilized to capture at least one of an inductance associated with the die level diagnostic cell circuitry stimulus driven diagnostic trace, a capacitance associated with the die level diagnostic cell circuitry stimulus driven diagnostic trace, an impedance associated with the die level diagnostic cell circuitry stimulus driven diagnostic trace, and a resistance associated with the die level diagnostic cell circuitry stimulus driven diagnostic trace.
