Patent ID: 7574637

Claim:
A system for concurrent testing of a plurality of electronic circuits, comprising: a primary test controller; and a plurality of local serial test controllers communicably coupled to the primary test controller, each local serial test controller being communicably coupleable to a respective electronic circuit to be tested, wherein the primary test controller is operative to provide serial stimulus data and serial expected data to each of the plurality of local serial test controller, and wherein each local serial test controller is operative; to receive the serial stimulus data and serial expected data from the primary test controller; to apply the serial stimulus data to the respective electronic circuit communicably coupleable thereto; to receive, substantially concurrently with the receipt of the serial expected data, serial resultant data generated by the respective electronic circuit in response to the application of the serial stimulus data; and to verify, on a bit-by-bit basis, the serial resultant data against the serial expected data as the serial resultant data is received from the expected electronic circuit, and as the serial expected data is received from the primary test controller.
