Abstract

Automated test equipment capable of performing a high-speed test of semiconductor devices is presented. The automated test equipment apparatus comprises a computer system comprising a tester processor, wherein the tester processor is communicatively coupled to a plurality of FPGA components. Each of the plurality of FPGA components is coupled to a memory module and comprises: an upstream port operable to receive commands and data from the tester processor; a downstream port operable to communicate with a respective DUT from a plurality of DUTs; and a plurality of hardware accelerator circuits, wherein each of the accelerator circuits is configured to communicate with one of the plurality of DUTs. Each of the plurality of hardware accelerator circuits comprises a pattern generator circuit configurable to automatically generate test pattern data and a comparator circuit configured to compare data.
