Abstract:
A method for increasing throughput and data capacity in a circuit tester used to program in-circuit programmable devices, comprising the steps of:segmenting programmable device data into a plurality of data segments; configuring a test sequencer to forward a first data segment to a first sequence memory device; acquiring the first data segment in the first sequence memory device; starting the test sequencer; forwarding the first data segment from the first sequence memory device and acquiring a subsequent data segment in a second sequence memory device; detecting a condition responsive to the completion of both the forwarding and acquiring steps associated with the respective first and second sequence memory devices; reconfiguring the test sequencer to forward the subsequent data segment from the second sequence memory device and to acquire a further subsequent data segment in the first test sequencer storage device; and repeating the detecting and reconfiguring steps to alternatively forward and acquire each subsequent data segment in the first and second sequence memory devices until the last of the plurality of data segments has been forwarded.
