    Abstract: The invention relates to a circuit cell for test pattern generation and test pattern compression of circuits with inbuilt self test functions which have a test data coupling circuit (6) comprising a test data input (5) for receiving a test data input signal TDI of an upstream circuit cell which can be saved in a test data intermediate memory, a data input (8) for applying a data input signal TDI which can be stored in a data intermediate memory, a test data output (15) for transmission of the intermediate stored test data signal TDI and a data output (16) for transmission of the intermediate-stored data output signal D to a data signal path via a data signal output (51) memories for the circuit cell. Both intermediate stores pertaining to the test data coupling circuit (6) have a common feedback signal path via which the received test data input signal TDI can be coupled to the data signal path depending on a first generated control signal TEST which can be coupled to the first data coupling circuit (6). A logical, comparitive circuit (26) is also provided which compares the test data input signal TDI with that of a transferred test data signal TD transferred from the test data coupling circuit (6) in order to generate a comparative signal which is transferred to a circuit device (21). Depending on a second control signal SCAN, the circuit device (21) transfers the generated comparative signal or the test data signal TD emitted by the test data coupling circuit to a test data signal output (48) pertaining to the circuit cell.

    Abstract: The method involves initializing one circuit cell as a test-pattern transmitting circuit cell, and one cell as a test-pattern receiving circuit cell. A generated test pattern is applied to the combinational circuit (3) for data processing by a memory unit of the test pattern transmitting circuit cell. Test data are read from the memory unit of the test pattern receiving cell by an automatic tester. An Independent claim is included for a circuit cell in an integrated circuit with a built-in self-test function.
