ABSTRACT:
A universal apparatus for the detection of faults in microprocessor systems. Microprocessors are commonly commercialized under the form of integrated circuits having a plurality of pins. The apparatus thus comprises a connector provided with pins so positioned that they can be inserted in the connection device of the microprocessor of a faulty system, in the place of the pins of this microprocessor after the same has been withdrawn. An interface defines for each pin of the connector a line having a programmable direction. A programmed controller associated with a memory which stores a copy of the software of the faulty system is connected to the interface for (a) programming the direction of the lines in order to simulate the interconnections which are normally established between the system and its microprocessor, and (b) carrying out tests on this system through the simulated interconnections for detecting the fault. The controller can of course be programmed to detect faults in a plurality of different microprocessor systems. The memory associated therewith then stores a copy of the software of all these systems.
