Abstract
An apparatus and method are provided for monitoring the voltage available in each domain of multiple voltage domains of a partitioned electronic 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.
