Abstract:
1. A test system for testing connectable integrated circuits, comprising: a supply unit for supplying an electrical signal to the integrated circuits; a switching device comprising a plurality of switches configured to selectively connect the integrated circuits to the supply unit; a single determination unit configured to determine an item of information about a power consumption of any integrated circuit to be tested; a threshold value generating circuit configured to generate a threshold value for the power consumption depending on a number of integrated circuits connected to the supply unit, and wherein the determination unit generates the item of information about the power consumption of each integrated circuit by comparing a value of the total power consumption of the integrated circuits connected via the switching device and the generated threshold value; and a control unit for controlling the switches; wherein the control unit, depending on the item of information, switches the switches in order to connect the integrated circuit to be tested to the supply unit or to isolate it from the supply unit during testing.
