摘要： The integrated circuit (10) has an internal power supply domain with a power supply voltage adaptation circuit (14) to adapt the power supply voltage in the power supply domain. Typically, a plurality of such domains is provided wherein the power supply voltage can be adapted independently. During testing an internal power supply voltage is supplied to a temporally integrating analog to digital conversion circuit (16) in the integrating circuit (10). A temporally integrated value of the power supply voltage is measured during a measurement period. Preferably, integrating measurements of a plurality of internal supply voltages are performed in parallel during the same measurement time interval. Preferably a further test is performed by changing over between mutually different supply voltages during a further measurement period. In this way the measured integrated supply voltage can be used to check the speed of the change over between the different voltages.

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： Sub-circuits of an integrated circuit can act as noise sources on common conductors such as power supply lines and the substrate. Each of these conductors may act as a noise medium capable of transferring noise signals from the noise source to other sub-circuits. One or more feedback circuits are coupled between input and output points on opposite sides of where a circuit to be protected is connected to such a medium, so that a output of the feedback circuit is coupled to the noise medium closer to certain noise sources than the input of the feedback circuit. Preferably, multiple feedback circuits are cross-coupled and have transfer connections so that coupling between the input and outputs of different feedback circuit is at least partially suppressed.
