Abstract: Embedding a discrete electrical device in a printed circuit board (PCB) includes: providing a vertical via as a blind hole from a horizontal surface of the PCB to an electrically conductive structure in a first layer, the first layer being one layer of a first core section of a plurality of core sections vertically arranged above each other, each core section including lower and upper conductive layers, and a non-conductive layer in between; inserting the electrical device into the via, with the device extending within at least two of the core sections; establishing a first electrical connection between a first electrical device contact device and the electrically conductive structure in the first layer; and establishing a second electrical connection between a second electrical device contact and a second layer, the second layer being one of the electrically conductive layers of a second horizontal core section.

Abstract: A method is provided for determining a power noise histogram of a computer system. The computer system includes a skitter circuit with multiple skitter bins, each skitter bin of the multiple skitter bins being connected to a signal line at one or more clock cycles. The method includes: connecting each skitter bin to an individual counter circuit; and incrementing a counter when the respective skitter bin is enabled.
