Abstract
An interface device is adapted to: in a first mode, in reaction to test signals and corresponding to a test standard, output signals corresponding to the test standard via at least one signal line. In a second mode it is adapted to, in reaction to test signals and corresponding to the test standard, output signals that do not correspond to the test standard via the at least one signal line.
Claims15
An integrated circuit, adapted to,
- in a first mode, in reaction to a received test signal corresponding to a test standard, feed through the test signal in unamended form to an output, to output a signal corresponding to the test standard via at least one signal line to a further integrated circuit to be tested, to carry out a standard-compliant test at the further integrated circuit to be tested, and
- in a second mode, in reaction to the received test signals corresponding to the test standard, output the test signal in converted form at the output, to output a signal that does not correspond to the test standard via the at least one signal line to the further integrated circuit to be tested, to carry out a not standard-compliant test at the further integrated circuit to be tested.
A method comprising:
- in a first mode of an interface device, in reaction to a received test signal corresponding to a test standard, feeding through the test signal in unamended form to an output, the interface device outputting a signal corresponding to the test standard via at least one signal line to a further integrated circuit to be tested, to carry out a standard-compliant test at the further integrated circuit to be tested;
- and
- in a second mode of said interface device, in reaction to the received test signal corresponding to the test standard, outputting the test signal in converted form at the output, said interface device outputting a signal that does not correspond to the test standard via the at least one signal line to the further integrated circuit to be tested, to carry out a not standard-compliant test at the further integrated circuit to be tested.
