    摘要： A circuit and a method for detecting noise events in a system with time variable operating points is provided. A switched capacitor filter comprising a plurality of capacitor units, samples a first voltage to determine an average of a set of voltage measurements, forming an average voltage. A filter control unit controls the plurality of capacitor units in the switched capacitor filter. A comparing unit compares the average voltage to the first voltage to form a comparison. A signaling unit generates a signal to instruct circuits in a processor to initiate actions to keep the first voltage from drooping below a threshold level in response to the comparison.

    摘要： A computer program product is provided for power delivery analysis and design for a hierarchical system. The product includes a storage medium, readable by a processing circuit, for storing instructions for execution by the processing circuit for facilitating a method. The method includes building a model corresponding to each element of the hierarchical system, and compiling a repository that contains models corresponding to each element, where the repository includes a net list, a domain list, a component list, a pin list, and a layer list. The method also includes performing optimized gridding for each element, the net list, the domain list, the component list, the pin list, and the layer list; assembling a system model from the models contained in the repository; flattening the system model by converting the system model to a flattened system model that consists entirely of resistors; and running a simulation on the flattened system model.

    摘要： An apparatus and method are provided for monitoring the voltage available in each domain of multiple voltage domains of a partitioned electronic chip. The apparatus comprises a single conductive link coupled to the chip, and further comprises a domain selection network having a single output and a plurality of switchable inputs, the output being connected to the single conductive link, and two inputs being connected to monitor respective voltage levels of two of the plurality of voltage domains. A control mechanism is disposed to operate the selection network, in order to selectively connect one of the inputs to the single conductive link, and a sensor device external to the electronic chip is connected to measure the monitored respective voltage levels of two of the plurality of voltage domains using the single conductive link.
