Abstract
A test interface board comprises at least one switch matrix including a plurality of switching elements that connect a plurality of connection nodes to each other. The at least one switch matrix is configured to connect a plurality of channels of an automatic test equipment (ATE) to respective pin positions corresponding to a device under test (DUT) in response to switching control signals. The plurality of channels provide test operation signals for testing the DUT. A control logic is configured to generate the switching control signals based on pin configuration information of the DUT.

14. A test system comprising:
-
an automatic test equipment (ATE) configured to generate test operation signals; a device under test (DUT) that receives the test operation signals to output test result signals in response to test pattern signals of the test operation signals; and a test interface board configured to transfer the test operation signals to the DUT, wherein the test interface board comprises; at least one switch matrix including a plurality of switching elements that connect a plurality of connection nodes to each other, the at least one switch matrix configured to connect a plurality of channels of the ATE to respective pin positions corresponding to the DUT in response to switching control signals, the plurality of channels providing test operation signals for testing the DUT; and a control logic configured to generate the switching control signals based on pin configuration information of the DUT. - View Dependent Claims (15, 16)

17. A test interface board, comprising:
-
a plurality of nodes arranged in a matrix having a first direction of extension and a second direction of extension, the first and second directions being transverse each other; a plurality of first switching elements configured to selectively connect adjacent nodes arranged in the first direction in response to switching control signals; a plurality of second switching elements configured to selectively connect adjacent nodes arranged in the second direction in response to the switching control signals; and a plurality of first positions corresponding to channels of an automated test equipment (ATE) and a plurality of second positions corresponding to pin positions of a device under test (DUT), wherein, in response to the switching control signals, the test interface board is programmed to provide multiple test signal paths, a signal path being between a selected one of the plurality of first positions and a selected one of the plurality of second positions, and the signal path further including a selected plurality of the nodes selectively connected by the first and second switching elements. - View Dependent Claims (18, 19, 20)
