Abstract
A circuit portion () of an IC comprises a plurality of conductive tracks () for coupling respective circuit portion elements (), e.g. standard logic cells, to a power supply rail (), with the conductive tracks () being coupled to the power supply rail () via at least one enable switch (). The circuit portion () further comprising an element () for determining a voltage gradient over the circuit portion () in a test mode of the integrated circuit (), which is conductively coupled to the conductive tracks (). The element () has a first end portion () for coupling the element () to the power supply terminal and a second end portion () for coupling the element () to the output () in the test mode. This facilitates IDDQ testing of the circuit portion () by means of measuring a voltage gradient over the element ().
