Abstract: A built-off test (BOT) device includes a signal processing block, an output selection block and a signal control block. The signal processing block duplicates a test signal to apply a plurality of duplicated test signals to each of a plurality of devices under test (DUTs) through each of corresponding channels, and the signal processing block provides a plurality of decision signals based upon a plurality of test result signals received from each of the DUTs. The output selection block merges the decision signals as a final decision signal or sequentially outputs the decision signals as the final decision signal, in response to an output mode selection signal. The signal control block provides the test signal to the signal processing block or provides the final decision signal externally, in response to a first switching control signal.

Abstract translation: 内置测试（BOT）设备包括信号处理块，输出选择块和信号控制块。 信号处理块复制测试信号，以通过每个相应的通道将多个复制的测试信号施加到被测设备（DUT）中的每一个，并且信号处理块基于多个测试信号提供多个决定信号 从每个DUT接收的测试结果信号。 响应于输出模式选择信号，输出选择块将决定信号合并为最终判定信号，或者顺序输出作为最终判定信号的判定信号。 信号控制块将测试信号提供给信号处理块，或响应于第一开关控制信号，向外部提供最终判定信号。
