Abstract
A test circuit arrangement for testing latch units is provided which includes a) a voltage generator configured to adjust a voltage potential difference between a first ground line and a second ground line of the latch units and/or to adjust a voltage potential difference between a first supply voltage line and a second supply voltage line of the latch units; b) combiner configured to combine logical outputs of the latch units; and c) determiner configured to determine the voltage potential difference between the first ground line and the second ground line and/or the voltage potential difference between the first supply voltage line and the second supply voltage line in a state when all of the latch units have identical logical outputs.
