    摘要: The present invention relates to a method and circuit arrangement for determining power supply noise of a power distribution network. The power supply noise is determined by measuring the propagation delay of a delay circuit powered by the power distribution network, wherein the result of the measuring step is used as an indicator of the power supply noise. Thereby, a real-time power supply noise monitoring can be carried out at any point of a power distribution network of an observed circuitry.

    摘要: The present invention relates to real-time adaptive control for best Integrated Circuit (IC) performance. The adaptive behavior is carried out on a local basis. The system is partitioned into different islands (30). Each island (30) is controlled and its working conditions are modified depending on some parameters. The remainder of the chip is controlled as well, depending on other parameters. This requires that each island (30) has a local controller (36) communicating with a global controller (42). The main control parameters are e.g. supply voltage, threshold voltage and clock frequency.

    摘要: A test apparatus for testing a device under test (DUT) to detect a defect comprises a measurement circuit (ME), a threshold circuit (TH), and a control circuit (CG). The measurement circuit (ME) comprises a counter (C1) which counts clock pulses (CLK) during a count period (TC) to obtain a counted number (N) of clock pulses (CLK). The count period (TC) has a start determined by the start (t1) of a testing cycle which occurs at the instant a switch (S) which is coupled to an terminal (IN) of the device under test (DUT) removes a power supply voltage (VDD) from the terminal (IN) and the voltage (VDD′) at the terminal (IN) starts decaying. An end of the count period (TC) is determined by an instant (t2) a comparator (COM1) detects that the voltage (VDD′) at the terminal (IN) crosses a reference value (VREF). The control circuit (CG) generates the clock signal (CLK) and/or a reference number (NTH) taking into account the variability of the manufacturing process of the circuit under test (CUT). The threshold circuit (TH) generates a pass/fail signal (PF) by comparing the counted number (N) and the reference number (NTH).

    摘要: A test apparatus for testing a device under test (DUT) to detect a defect comprises a measurement circuit (ME), a threshold circuit (TH), and a control circuit (CG). The measurement circuit (ME) comprises a counter (C1) which counts clock pulses (OLK) during a count period (TC) to obtain a counted number (N) of clock pulses (CLK). The count period (TC) has a start determined by the start (tl) of a testing cycle which occurs at the instant a switch (S) which is coupled to an terminal (IN) of the device under test (DUT) removes a power supply voltage (VDD) from the terminal (IN) and the voltage (VDD′) at the terminal (IN) starts decaying. An end of the count period (TC) is determined by an instant (t2) a comparator (COM1) detects that the voltage (VDD′) at the terminal (IN) crosses a reference value (VREF).
