    摘要: A test device for testing a plurality of semiconductor devices, each of which includes a plurality of functional blocks and a plurality of test pads coupled to the functional blocks. The test device includes a test header including a plurality of test channels, a plurality of test sites on which the semiconductor devices are installed, and a test control device. The test control device allocates the test channels to at least some of the test pads of the semiconductor devices to test more than two of the semiconductor devices simultaneously. The number of the test sites is greater than a value generated by dividing the number of the test channels by the number of the test pads of each of the semiconductor devices.

    摘要: A backplane testing system includes a test backplane coupled to a test device chassis and including a first connector system, a second connector system, and channels that connect the first connector system and the second connector system. A first test device in a first test device slot on the test device chassis engages the first connector system and provides a loop back circuit for the first connector system. A second test device in a second test device slot on the test device chassis engages the second connector system. The second test device sends a test signal through a channel on the test backplane such that the test signal is provided to the loop back circuit on the first test device and received back through the channel. The second test device analyzes the test signal that is received to determine a testing compliance of the channel on the test backplane.

    摘要: A module that incorporates a chassis for enabling use of at least one smaller functional module in at least one slot of a chassis designed to mate with a larger functional module having a different standard than the smaller functional module. The module has a housing having electrical connections adapted to mate with electrical connections provided by the chassis for the larger functional module and dimensions that fit within at least one slot provided by the chassis for housing the larger functional module. The module includes at least one set of electrical connections adapted to mate with the electrical connections of the smaller functional module(s) and at least one air passage for conveying air from an opening of the chassis that provides air flow to cool the larger functional module to an area in which the smaller functional module(s) is/are situated when mated with the housing.

    摘要: A test card for testing one or more devices under test includes a plurality of test resources configured to communicate with the one or more devices under test. The test card further includes a matching circuit configured to receive a test sequence of at least two matching instructions followed by one or more processing instructions. The matching instructions define a group of resources which are to operate in accordance with the processing instructions. The matching circuit is configured to determine based on the at least two matching instructions whether a given test resource out of a plurality of test resources belongs to the group or not and to forward the processing instructions to the given test resource if the given test resource belongs to the group and to not forward the processing instructions to the given test resource if the given test resource does not belong to the group.

    摘要: A method for performing test site synchronization within automated test equipment (ATE) is presented. The method comprises controlling a plurality of test program controllers (TPCs) using a plurality of bridge controllers (BCs), wherein each TPC can initiate multiple asynchronous events. For an asynchronous event initiated by a TPC, raising a busy flag while the asynchronous event is not yet complete and de-asserting the busy flag when the asynchronous event is complete, wherein the asynchronous event corresponds to a task requiring an indeterminate amount of time. It also comprises generating a busy signal in the first BCs in response to receiving a busy flag from any of the plurality of TPCs, wherein the busy signal remains asserted while any of the plurality of TPCs asserts a busy flag. Finally, it comprises transmitting the busy signal to the plurality of TPCs, wherein the TPCs use the busy signal to synchronize operations.
