摘要： Forming of a statistical model for a set of independently variable parameters for analysis of a circuit design is disclosed. In one embodiment, a method includes establishing a timing model including delay and delay changes due to process parameter variations (Pi) that impact timing; selecting an element of the circuit design that dominates circuit delay in the timing model; determining a delay sensitivity of each of a set of derived process parameters (Vj) for the element that are linear combinations of the process parameter variations (Pi); and selecting only those derived process parameters with a high sensitivity for use in the statistical model. The invention simplifies the statistical model and reduces the number of calculations require for timing analysis. A method of performing a timing analysis using the simplified statistical model is also disclosed.

摘要： A method for performing an electromigration check and detecting EM problems in a device or circuit. The method uses the capacitance and resistance of the conductors of the device or circuit as parameters in determining a power limit that maintains a required temperature environment that ensures the reliability of the device or circuit. The parameters of resistance and capacitance can be determined for the device or circuit through the use of commercially available device data or simulation and analysis tools. The power limit is then used to check each device interconnect to identify the location of potential EM problems. Corrective action is taken to avoid EM problems as they are detected in the device or circuit.

摘要： A method and service of balancing delay in a circuit design begins with nodes that are to be connected together by a wiring design, or by being supplied with an initial wiring design that is to be altered. The wiring design will have many wiring paths, such as a first wiring path, a second wiring path, etc. Two or more of the wiring paths are designed to have matching timing, such that the time needed for a signal to travel along the first wiring path is about the same time needed for a signal to travel along the second wiring path, the third path, etc. The method/service designs one or all of the wiring paths to make the paths traverse wire segments of about the same length and orientation, within each wiring level that the first wiring path and the second wiring path traverse. Also, this process makes the first wiring path and the second wiring path traverse the wire segments in the same order, within each wiring level that the first wiring path and the second wiring path traverse.

摘要： A system and method of performing microelectronic chip timing analysis, wherein the method comprises identifying failing timing paths in a chip; prioritizing the failing timing paths in the chip according to a size of random noise events occurring in each timing path; attributing a slack credit statistic for all but highest order random noise events occurring in each timing path; and calculating a worst case timing path scenario based on the prioritized failing timing paths and the slack credit statistic. Preferably, the random noise events comprise non-clock events. Moreover, the random noise events may comprise victim/aggressor net groups belonging to different regularity groups. Preferably, the size of random noise events comprises coupled noise delta delays due to the random noise events occurring in the chip.

摘要： Methods for analyzing the timing in integrated circuits and for reducing the pessimism in timing slack calculations in static timing analysis (STA). The methods involve grouping and canceling the delay contributions of elements having similar delays in early and late circuit paths. An adjusted timing slack is calculated using the delay contributions of elements having dissimilar delays. In some embodiments, the delay contributions of elements having dissimilar delays are root sum squared. Embodiments of the invention provide methods for reducing the pessimism due to both cell-based and wire-dependent delays. The delays considered in embodiments of the invention may include delays due to the location of elements in a path.
