    • In order to test the input and output drivers of a circuit, in particular an integrated semiconductor circuit, a method and apparatus is provided to connect the input or output drivers assigned to individual signal connections of the circuit to be tested in series to a ring oscillator or to an open chain with the oscillation of the ring oscillator or the delay time being evaluated. By providing appropriate controllable switches, the configuration of the ring oscillator or the chain can be altered variably depending on the input or output drivers to be tested respectively. In this way an “at-speed” and “leakage” test of all input and output drivers, including the external signal connections, are possible with all of these having to be connected to a rapid test unit.

    • A test device contains a data pattern generator for providing a delta-sigma-modulated data stream sampled with a sampling frequency fs at its output. A phase modulator generates a test clock subjected to jitter and having the clock frequency ft at its output. The output of the data pattern generator is connected to a terminal for connection to a data input of a semiconductor component to be tested. The output of the phase modulator is connected to a terminal for connection to a clock input of a semiconductor component to be tested. An evaluation device determines the jitter parameters of the input signal at the input of the data device from the low-frequency component of the input signal. In this case, the low-frequency component contains only frequency components of frequencies which are less than half the sampling frequency fs/2.
    • 测试装置包含一个数据模式发生器,用于提供在其输出端以采样频率fs采样的Δ-Σ调制数据流。 相位调制器产生经受抖动的测试时钟,并在其输出端具有时钟频率ft。 数据模式发生器的输出端连接到用于连接到要测试的半导体元件的数据输入端的端子。 相位调制器的输出连接到用于连接到要测试的半导体部件的时钟输入的端子。 评估装置从输入信号的低频分量确定数据装置的输入处的输入信号的抖动参数。 在这种情况下,低频分量仅包含小于采样频率fs / 2的一半的频率的频率分量。
