    摘要: To determine the period length of a first signal, the length is measured by counting the periods of a second signal with a shorter period length. To measure the fluctuations of the period length of the first signal whilst also taking into account the fluctuations of the period length of the second signal, the measurement is carried out for two different values of the period length of the second signal. Both the fluctuations of the period length of the first signal and the accumulated fluctuations of the period length of the second signal are calculated independently of one another from the two values. The method enables the period length fluctuations of a first signal that originates from a phase-locked loop to be detected.

    摘要: 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.

    摘要: An electric tolerance analysis circuit for digital and digitized measured values has inputs for receiving a measured value, a reference value, and a tolerance value and also an output for transmitting an output value. The electric tolerance analysis circuit also has a checking device for checking the measured value using at least one prescribable tolerance criterion and has an output device for outputting an output value which is obtained from the state of the checking device, depending on whether or not the measured value meets the respective prescribed tolerance criterion.
