    Abstract: A design method and system for minimizing blind via current loops provides for improvement of electrical interconnect structure design without requiring extensive electromagnetic analysis. Other vias in the vicinity of a blind via carrying a critical signal are checked for suitability to conduct return current corresponding to the critical signal that is disrupted by the transition from a layer between two metal planes to another layer. The distance to the return current via(s) is checked and the design is adjusted to reduce the distance if the distance is greater than a specified threshold. If the blind via transition is to an external layer, suitable vias connect the reference plane at the internal end of the blind via to an external terminal. If the transition is between internal layers, suitable vias are vias that connect the two reference planes surrounding the reference plane traversed by the blind via.

    Abstract: A system for mitigating power supply and power distribution system noise response by throttling execution units based upon voltage sensing in a circuit is provided. A sensing unit senses the voltage of a circuit. The sensing unit determines if the execution of another execution unit will cause the circuit voltage to drop below a threshold level. In response to a determination that the execution of another execution unit will cause the circuit voltage to drop below the threshold level, the execution unit is throttled.

    Abstract: A system for minimizing the length of the longest diagonal interconnection. A multiple chip module may comprise a first chip connected to a second chip located diagonally to the first chip. The first and second chip are interconnected by one or more interconnections commonly referred to as diagonal interconnections. Since the one or more diagonal interconnections between the first chip and the second chip are interconnected between a set of pins on each chip that form a triangular pattern, the longest diagonal interconnection is substantially the same length as the length of the longest orthogonal interconnection. Furthermore, since the one or more diagonal interconnections between the first chip and the second chip are interconnected between a set of pins on each chip that form a triangular pattern, the longest diagonal interconnection is substantially the same length as the length of the second longest diagonal interconnection.

    Abstract: Manufacturing circuits with reference plane voids over vias with a strip segment interconnect permits routing critical signal paths over vias, while increasing via insertion capacitance only slightly. The transmission line reference plane defines voids above (or below) signal-bearing plated-through holes (PTHs) that pass through a rigid substrate core, so that the signals are not degraded by an impedance mismatch that would otherwise be caused by shunt capacitance from the top (or bottom) of the signal-bearing PTHs to the transmission line reference plane. In order to provide increased routing density, signal paths are routed over the voids, but disruption of the signal paths by the voids is prevented by including a conductive strip through the voids that reduces the coupling to the signal-bearing PTHs and maintains the impedance of the signal path conductor.

    Abstract: A function of an integrated circuit is selectively disabled by mechanical intervention at a module that contains the integrated circuit, such as drilling a hole through the module, cutting a slot in the module or burning a hole with a laser through the laser. Mechanical destruction of the module at a predetermined spot disrupts a function enable signal that is otherwise provide through wires of the module to a connection with the integrated circuit. Without the function enable signal from the module wires to the integrated circuit connector, the function associated with the function enable signal cannot run on the integrated circuit.
