In-Situ Electrical Connectivity Detection

A computer-implemented method, comprising:

• transmitting a signal out from a package interface of a computing device;
• receiving and measuring a reflection of the signal at the package interface;
• and
• characterizing an electrical connection to the package interface based on the measured reflection.

A computing system, comprising:

• a package on a substrate, a first interconnect interface of the package coupled with a second interconnect interface of the substrate, the package configured to couple with one or more devices through the substrate;
• a transmitter in the package, the transmitter coupled to the first interconnect interface and configured to transmit a signal from the package to at least one device of the one or more devices via the second interconnect interface;
• and
• a receiver in the package, the receiver coupled to the first interconnect interface and configured to measure a reflection of the transmitted signal, the measured reflection used to characterize an electrical connection between the package and the at least one device.
