摘要： A method of detecting and preventing over current induced system failure is provided. An OC protect controller monitors a CPU total power consumption based on received CPU activity information. In response to the monitoring, if the CPU power consumption is over a threshold, then the OC protect controller outputs a frequency dithering control signal to reduce the CPU clock frequency such that the CPU does not reach an OC limit. The OC protect controller also outputs a PLL frequency control signal to reduce the PLL clock frequency to improve system efficiency.

摘要： A method includes parsing a design of the integrated circuit to define cells in automatic power gating power domains, automatically creating an automatic power gating power domain netlist from the parsed design of the integrated circuit, and placing and routing the automatic power gating power domain netlist to produce a layout for the integrated circuit. The parsing partitions a high-level power domain of the integrated circuit into one or more automatic power gating power domains. The automatic power gating power domains have substantially zero-cycle power up times, thereby enabling transparent operation. Furthermore, the automatic power gating power domains may be automatically inserted into designs of integrated circuits, thereby relieving integrated circuit designers of the task of inserting power domains and associated hardware and software.

摘要： A method is described for simulating the f-sigma timing path delay of an integrated circuit design when local transistor variations determine the stochastic delay. This is achieved by determining an estimated delay time for a first timing path using non-linear operating point analysis of local variations (NLOPALV). An operating point is calculated for each cell that is included in a timing path in the integrated circuit design. The f-sigma operating point of a cell-arc is a point on the cell-arc delay function (CADF). An f-sigma delay value is determined for each cell using the selected operating point on the CADF of the cell. The determined delay values of the plurality of cells in the timing path may then be combined to predict the estimated delay for the entire timing path. The method may be extended to deal with slew rate, predict hold time statistics, prune paths, and deal with convergent paths.
