Abstract: Various communication systems may benefit from determining a venue value index before deploying wireless communication in the area. A method may include identifying the one or more wireless coverage issues within an area. The method may also include receiving data demand information for the area having the identified one or more wireless coverage issues. In addition, the method may include receiving or determining a total cost of ownership. The total cost of ownership may include a cost of fixing the one or more wireless coverage issues within the area. Further, the method may include calculating a venue value index of the area based on at least one of the total cost of ownership, the data demand information, or an average spectrum efficiency. The method may in addition include performing at least one network administrative task based on the venue value index.

Abstract: Simulation waveforms representative of simulation progress are generated and outputted for display. A netlist describing a circuit is accessed, and the circuit is simulated over a simulation runtime period. A simulation completion measurement is determined for the simulation runtime period, and a simulation waveform is generated based on the determined simulation completion measurement. Other simulation waveforms can be generated, for instance waveforms representative of a processing resource load over the simulation runtime period. Multiple simulation waveforms can be correlated and displayed in conjunction with each other, for instance in a common waveform interface.

Abstract: A system, computer-readable storage medium, and method directly solves non-linear systems that have the HB Jacobian as the coefficient matrix. The direct solve method can be used to efficiently simulate non-linear circuits in RF or microwave applications. Additionally, the direct solve method can be applied to Fourier envelope applications. Furthermore, the direct solve method can be used together with preconditioners to provide a more efficient iterative solve technique.

Abstract: A computer-implemented method computes the steady-state and control voltage of a voltage controlled oscillator, given a known frequency or a known period of oscillation of the voltage controlled oscillator. Differential algebraic equations representative of the voltage controlled oscillator are generated, where the differential algebraic equations includes a known period or frequency of oscillation and an unknown control voltage of the voltage controlled oscillator. The differential algebraic equations are modified using a finite difference method, a shooting method, or a harmonic balance method, to obtain a set of matrix equations corresponding to the differential algebraic equations. A solution to the matrix equations is obtained using a Krylov subspace method, using a preconditioner for the Krylov subspace method that is derived from a Jacobian matrix corresponding to the matrix equations, where the solution includes the control voltage of the voltage controlled oscillator in steady state.

Abstract: A technique to design deep sub-micron (DSM) integrated circuits is disclosed, in which global wire delays are minimized first, before performing logic synthesis. According to the present method, a designer performs layout of physical blocks by estimating an area for each block. After connecting the pins of the blocks with no timing constraints, each wire is assigned to a metal layer, based on length. The delay of each wire is minimized by inserting buffers at optimal distances. The blocks are then partitioned into “cores” and “shells.” The shells and cores are synthesized, and then recombined. This procedure greatly reduces the number of design iterations required to complete a design.

Abstract: A nonlinear analysis for characterizing phase noise and timing jitter in oscillators is disclosed. The method and apparatus utilize a nonlinear differential equation to characterize the phase error of a given oscillator. A precise stochastic characterization of timing jitter and spectral dispersion is also disclosed based on the nonlinear differential equation. Representative time and frequency domain computational techniques are disclosed for characterizing the phase noise and timing jitter of circuits. In addition, a single scalar constant, c, is utilized to describe jitter and spectral spreading in a noisy oscillator.
