Abstract

The present invention discloses a probing system for integrated circuit devices, which transmits testing data between an automatic test equipment (ATE) and an integrated circuit device. The ATE includes a first transceiving module, and the integrated circuit device includes a core circuit, a built-in self-test (BIST) circuit electrically connected to the core circuit, a controller configured to control the operation of the BIST circuit, and a second transceiving module configured to exchange testing data with the first transceiving module. Preferably, the integrated circuit device further includes a clock generator and a power regulator electrically connected to the second transceiving module, wherein the ATE transmits a radio frequency signal via the first transceiving module, and the second transceiving module receives the radio frequency signal to drive the power regulator to generate power for the integrated circuit device to initiate the BIST circuit.
