PROCESS FOR MAKING AN ELECTRIC TESTING OF ELECTRONIC DEVICES
First Claim
1. A process for electrically testing an electronic device, the process comprising:
- coupling the electronic device to an automatic testing apparatus suitable for testing digital circuits;
sending control signals through said automatic testing apparatus to electrically test said electronic device;
coupling a reconfigurable digital interface to said automatic testing apparatus and to said electronic device through a dedicated digital communication channel having a limited number of communication lines configured to exchange test information between the automatic testing apparatus and the electronic device;
testing said electronic device through said reconfigurable digital interface; and
sending from said electronic device to said automatic testing apparatus response messages containing test result data in response to said control signals, the response messages being sent through said dedicated digital communication channel.

Abstract
The disclosure relates to a process for making an electric testing of electronic devices DUT, of the type comprising the steps of: connecting at least one electronic device DUT to an automatic testing apparatus or ATE apparatus suitable for making the testing of digital circuits; sending, through said ATE apparatus, control signals for the electric testing to said electronic device DUT. Advantageously, the process also comprises the steps of: making the electric testing of said electronic device DUT through at least one reconfigurable digital interface RDI connected to said ATE apparatus through a dedicated digital communication channel and comprising a limited number of communication or connection lines strictly appointed to the exchange of the testing information; and sending from said electronic device DUT to said ATE apparatus response messages, if any, containing measures, failure information and data in response to said control signals and through said digital communication channel.
