    • An apparatus for multiplying a semiconductor test pattern signal is disclosed. The multiplying apparatus firstly encodes a plurality of pattern signals to have different pattern types, and multiplies the encoded pattern signals according to an exclusive-OR (XOR) scheme in order to generate a single pattern signal, thereby recognizing a relationship between a pattern signal before the multiplication and the other pattern signal after the multiplication. A pattern-signal segmenting/outputting unit segments a semiconductor test pattern signal into a plurality of pattern signals, and simultaneously outputs the segmented pattern signals. A pattern-signal restoring/multiplying unit restores the segmented pattern signals received from the pattern-signal segmenting/outputting unit to the semiconductor test pattern signal, outputs the restored result to a driver which records a test pattern in an objective semiconductor to be tested, and multiplies the signal outputted to the driver by a predetermined frequency band rather than a frequency band of the segmented signals.
    • 公开了一种用于乘以半导体测试图案信号的装置。 乘法装置首先对多个图案信号进行编码以具有不同的图案类型,并且根据异或(XOR)方式对编码图案信号进行乘法,以便生成单个图案信号,从而识别出之前的图案信号之间的关系 乘法和乘法后的其他模式信号。 图案信号分割/输出单元将半导体测试图案信号分割成多个图案信号,并且同时输出分割的图案信号。 模式信号恢复/乘法单元将从图案信号分割/输出单元接收到的分段图形信号恢复到半导体测试图形信号,将恢复结果输出到测试图案记录在要测试的目标半导体中的驱动器, 并且将输出到驱动器的信号乘以预定频带而不是分段信号的频带。

    • A signal generator produces an output clock signal by coupling an input clock signal through a plurality of divider circuits each of which is formed by a toggling flip-flop. The frequency of the output clock signal is adjusted by selecting the flip-flop to which the input clock signal is coupled. Retimer flip-flops may be coupled between adjacent flip-flips to resynchronize the signal being coupled through the flip-flops. Each of the retimer flip-flops receives a respective signal from the output of an upstream flip-flop at its data input, and it receives the input clock signal at its clock input. The flip-flop then applies the signal to a downstream flip-flop in synchronism with the input clock signal. The final two flip-flops through which the input signal is coupled may be preset to various states to set the phase of the output clock signal to one of four phases.
    • 信号发生器通过将输入时钟信号通过多个分频器电路产生输出时钟信号,每个分频器电路由触发触发器形成。 通过选择耦合输入时钟信号的触发器来调整输出时钟信号的频率。 重定时器触发器可以耦合在相邻的翻转翻转之间,以重新同步通过触发器耦合的信号。 每个重定时器触发器在其数据输入处从上游触发器的输出接收相应的信号,并且在其时钟输入端接收输入时钟信号。 然后触发器与输入时钟信号同步地将信号施加到下游触发器。 输入信号耦合的最后两个触发器可以预设为各种状态,以将输出时钟信号的相位设置为四相中的一个。
