Abstract: Some embodiments include apparatuses and electrical models associated with the apparatus. One of the apparatuses includes an integrated circuit having a die; a package substrate; first conductive connections coupled between the die and a first side of the package substrate; second conductive connections located on a second side of the package substrate opposite from the first side. The second conductive connections are coupled to the first conductive connections through conductive paths in the package substrate. The first conductive connections and the conductive connections are associated with an S-parameter of an electrical model of the integrated circuit package. The electrical model further includes at least one of a current value associated with a power rail of the integrated circuit package, an impedance target associated with a location at the integrated circuit package, and a mapping associated with the first and second conductive connections.

Abstract: Embodiments of a power regulation circuit that ameliorates a first and second droop in a power source voltage that powers a processing core are disclosed. The power regulation circuit includes a first droop detector, a second droop detector and a frequency slowdown detection circuit. The first droop detector generates a first droop detection signal in a first detection state in response to detecting a first droop in the power source voltage. The second droop detector generates a second droop detection signal in a second detection state in response to detecting a second droop in the power source voltage. The frequency slowdown detection circuit to generate a frequency slowdown signal in a slowdown state in response to at least one of the first droop detection signal being in the first detection state and the second droop detection signal being in the second detection state.
