摘要： A low inductance via arrangement for multilayer ceramic (MLC) substrates is provided. With the MLC substrate and via arrangement of the illustrative embodiments, the via-field inductance for a given contact pad array is reduced. This reduction is achieved by the introduction of T-jogs and additional vias. These T-jogs and additional vias form additional current paths that cause additional parallel inductances that reduce the via-field inductance. In one illustrative embodiment, the additional T-jogs and vias are added to a center portion of a contact pad array. The T-jogs are comprised of two jogs in a wiring layer of the MLC, each jog being toward a via associated with an adjacent contact pad in the contact pad array. These additional T-jogs and vias form additional current loops parallel to the existing ones which thus, reduce the total inductance of the via-field.

摘要： An apparatus and method are provided for monitoring the voltage available in each domain of multiple voltage domains of a partitioned electronic chip. In embodiments of the invention, only a single pair of C4 pins is required for all voltage monitoring activity. One useful embodiment is directed to apparatus for monitoring the level of voltage associated with each domain in a partitioned chip. The apparatus comprises a single conductive link coupled to the chip, and further comprises a domain selection network having a single output and a plurality of switchable inputs, the output being connected to the single conductive link, and two inputs being connected to monitor respective voltage levels of two of the plurality of voltage domains. A control mechanism is disposed to operate the selection network, in order to selectively connect one of the inputs to the single conductive link, and a sensor device external to the electronic chip is connected to measure the monitored respective voltage levels of two of the plurality of voltage domains using the single conductive link.
