Abstract: The invention allows the inclusion of cross-talk coupling and other noise in circuit simulation by considering a resultant glitch in more detail than just its peak value. A set of parameters represents the noise, with an exemplary embodiment using a triangle approximation to a glitch based on a set of three parameters: the peak voltage value, the leading edge slope and the trailing edge slope. These values are then used as the input stimulus to a given cell instance in the network in which the resulting propagated noise values, also in a triangle approximation, are determined by a simulation. The results can be stored as a library so that, given the parameters of the input noise and the particular cell, a simulation can determine the propagated noise through a look-up process. To reduce the space requirements of the library, the dimensionality of the look-up tables can be reduced through the introduction of a set of auxiliary functions to offset error from this reduction.

Abstract: A method and circuit arrangement for determining performance of a digital circuit to a critical degree by the transit time of signals of the longest signal path, also called the critical path. Since the signal transit time is influenced by the operating voltage, by regulating the operating voltage, to compensate for the effects caused by temperature and process fluctuations on the signal transit time in the digital circuit. In particular, the operating voltage can be regulated as a function of the signal transit time in such a way that a required minimum operating frequency can always be achieved. To determine signal transit time, the digital circuit has associated with it a number of replicas of the critical path in the digital circuit upon which the signal transit time is determined. In order to determine the transit time, the signal path replicas are exposed to the same operating conditions as the digital circuit.

A current change rate observed for a simulation window is then used to convert back to actual I/Os to create the equivalent model. The equivalent model can be simulated using conventional software, e.g., SPICE, for more detailed analysis such as signal integrity, timing of I/Os and noise.

Abstract: An improved method for debugging of analog and mixed signal behavioral models during simulation using Newton-Raphson iteration replay. The method according to the invention has substantially modified the prior art solution by limiting the interactive debugging steps in a replay of the last iteration of the accepted timepoints. Using this method, the user only interacts with the simulation during the iteration replay, and only for the accepted solution points. If the user is single stepping through this simulation, the simulator enters interactive mode at each statement during the replay. Similarly, if not single stepping, but a breakpoint has been triggered, the simulator enters the interactive mode at the appropriate statement to honor the breakpoint. While the iteration replay is performed, the system of equations does not need to be solved again. Instead, the solution vector is reinstated from the known solution of the last iteration.

Abstract: Constant components and rotation fundamental mode components on the slide plane between a rotor and a stator are derived from a magnetic field distribution at a predetermined time. The analysis space is divided into a rotor space and a stator space. A fundamental mode on the slide plane is rotated by a rotation angle of a rotation magnetic field corresponding to a time-step width.

The rotation fundamental mode on the slide mode is rotated by an angle obtained by subtracting the rotation angle of the rotor from the rotation angle of the rotation magnetic field corresponding to the time-step width.

Abstract: A method for providing independent static and dynamic models in a prediction, control and optimization environment utilizes an independent static model (20) and an independent dynamic model (22). The static model (20) is a rigorous predictive model that is trained over a wide range of data, whereas the dynamic model (22) is trained over a narrow range of data. The gain K of the static model (20) is utilized to scale the gain k of the dynamic model (22).

This is facilitated by a coefficient modification block (40). Thereafter, the difference between the new value input to the static model (20) and the prior steady-state value is utilized as an input to the dynamic model (22). The predicted dynamic output is then summed with the previous steady-state value to provide a predicted value Y.
