Cell with fixed output voltage for integrated circuit

摘要

The invention relates to a testable integrated circuit. In order to replace ground and VDD in certain points of such a circuit, the circuit comprises a cell (34) which comprises a flipflop (11) and means (31) able to set the output voltage of the cell when the circuit is in the operation mode. These means for setting the output voltage are controlled by a control signal (15) which depends on the mode signal that indicates whether the signal is in the test mode or in the operation mode.
