PROCESS AND DEVICE FOR TESTING THE OPERATION OF AN ELECTRONIC UNIT BY SIMULATION AND TEST INSTALLATION OF UNIT TO BE MOUNTED ON RAILWAY ROLLING STOCK OR AN ELECTRIC VEHICLE

摘要

A simulator (11) equipped with at least one microprocessor (14) sends to the unit to be tested (1) input simulation signals (E) and receives output signals (S) therefrom in response. The method consists of processing, as and when they are transmitted, some (S1) output signals of the unit by means of at least one programmable logic circuit (18), to store parameter values corresponding to these signals. processed and access the microprocessor (14) to the stored parameter values at a frequency compatible with its operating speed. The device makes it possible to implement the method. The simulator (11) comprises at least one programmable logic circuit (18), for example of the FPGA type, able to receive some (S1) at least of the output signals (S) of the electronic unit (1).
