Functional test of calculation devices in the course of manufacture of functional tests based on firmware applied by means of the port of the developed by the emulation device.

摘要

The present invention relates to a test system in the course of manufacture in order to test a computing system (39), comprising a calculation device (36) to (37) of the point in the emulation accessible through a port (38) of the point in the emulation, by applying functional tests on the basis of the device by the port firmware. It comprises a functional test (35) based on a microprogram; and a probe (34) of calculation system which communicates with the device by the port for controlling an embodiment and to modify and to recover the values of internal state of the calculation system, the probe which, via the port, apply the functional test to the system of calculation and control the execution of the test at each level of integration test of such a system. Preferably, a host computer (32) can send the test to the probe. The present invention also relates to a corresponding method.
