    • PURPOSE:To detect immediately a faulty gate circuit by providing a counter within a device to be tested to count the shift number of clocks and referring to the count number from the count starting time point in a test mode. CONSTITUTION:A counter 11 exclusive for fault check is incorporated into a device 1 to be tested, and the count value of the counter 11 is displayed. This counter 11 is updated with the scan clock and receives +1 every time FF trains 1-1-1-N are shifted by a bit. Then the counter 11 is reset as soon as the FF train is reset, and the count value is set so as to have the complete coincidence with the FF train. As a result, a faulty FF can be immediately detected from the count value of the counter 11.
    • 目的:通过在要测试的设备内提供计数器来计数时钟的移位数,并参考测试模式下的计数开始时间点的计数,立即检测故障门电路。 构成:将要进行故障检查的计数器11并入要测试的装置1中,并显示计数器11的计数值。 该计数器11用扫描时钟更新,每当FF列1-1-1-N偏移一位时接收+1。 然后,一旦FF列车复位,计数器11被复位,并且计数值被设定为与FF列车完全一致。 结果,可以从计数器11的计数值立即检测到故障FF。
