Abstract: A component design tool extracts a parameter associated with a component defined in a model of a physical system. The design tool discretizes the component and generates a matrix representative of a specified parameter. By subdividing the matrix into a hierarchy of submatrices and iteratively compressing and blending the submatrices, the design tool produces a compressed matrix. The compressed matrix is efficiently solved using iterative techniques. From the solution of the matrix, the design tool calculates the specified parameter.

Abstract: Integrated circuit chips (IC's) require proper placement of many cells (groups of circuit components) and complex routing of wires to connect the pins of the cells. Because of the large number of the cells and the complex connections required, it is essential that placement of the cell and the wire routine be done correctly to avoid any congestion of wires. The present invention discloses method and apparatus to reduce or to eliminate cell placement and wire routing congestion. To reduce vertical congestion, the cells are moved from congested regions to uncongested regions. The present invention discloses techniques of defining regions as pieces and columns, determining the level of congestion in the regions, and the methods of moving the cells to different columns to reduce congestion while minimizing affects to wire routing. The movement of the cells to other columns may create overlapping of the cells or overloading of the columns.

Abstract: Upon a transient analysis simulation, if a time step between calculation points is relatively small, a forced quit error occurs, which leads to deterioration of development efficiency. A voltage v.sub.n at a calculation point t.sub.n is obtained by solving a circuit equation. A change rate in the voltage v.sub.n in a step [t.sub.n-1, t.sub.n ] is assumed to be maintained in another step [t.sub.n, t.sub.n+1 ], and a calculation point t.sub.n+1 is temporarily determined so that v.sub.n+1 -v.sub.n is equal to a predetermined value .DELTA.v. The step t.sub.n+1 -t.sub.n is then judged if it falls within a dynamic range of a computer. If the step does not fall within the dynamic range, the calculation point t.sub.n is moved backward by a predetermined decrement, and the procedure is re-performed. If t.sub.n+1 -t.sub.n falls within the dynamic range, a voltage at the calculation point t.sub.n+1 is calculated.

Abstract: The present invention discloses a method for constructing the fault classification tables of analog circuits, and the fault classification tables can be further applied to construct analog CAT tools. The constructing method uses the fault models but the normal models inserting in parts of the analog circuit components, and then utilizes a circuit simulator to obtain waveform from the defect analog circuit. Exclusive and non-exclusive classification schemes are applied to establish the failure modes of the defect analog circuit when the waveform is recorded as a fault dictionary. It is unnecessary to construct a real analog circuit as the conventional does.

Abstract: A simulation input and a model file are generated. The simulation input file is processed to generate object code, entries, line counts, and comment lines. A simulation program is run that uses the object code, entries, line counts, and input comment lines. A machine captures and links output comment lines with their associated test vectors by using the entries and line counts to form a simulation results file. After the simulation, the simulation results file can be reviewed. After simulation, masks (30, 40, 50, 60, 70) are generated that are used to form integrated circuits (20). The present invention can also be used for testing integrated circuits. The test methods use a test input file generated from the simulation results file.

Abstract: The invention features a system and method to enable real-time establishment and maintenance of a standard of operation for a data communications network. The standard is a data set which includes network activity which is historically categorized by traffic type and by activity. The process begins with monitoring the network media or some network component over some period of time. The monitoring information is used to build benchmark data sets. The benchmark data sets contain a standard of operation for the network, which are historically categorized by either traffic type or activity. This standard of operation is constantly built by the intelligent monitoring facilities. After some period of time which is referred to as the benchmark data set refresh interval, the benchmark that was created is employed in a fashion to allow a determination as to whether the data that is taken from the current monitoring activity indicates normal network behavior.

When the values for U.sub..alpha.x and U.sub..beta.x are represented graphically, peaks are predicted to represent regions of .alpha. and .beta. structure, respectively.

Abstract: A computer-based method and system describes molecules in a most fundamental and compact way using a set of attributes of the molecule derived from data representing the atomic structure and atomic charge of the molecule. The attributes include the shape of the molecule as defined by the moment of inertia of the molecule, the charge distribution of the molecule as defined by a novel representation of molecular quadrupole, and/or attributes that represent the relationship of the shape to the charge distribution of the molecule. A set of these physical attributes are represented by a set of descriptors. The set of descriptors may be used for molecular matching and activity prediction, as well as in 3D-QSAR analysis.

Abstract: A method of analyzing clinically relevant sample liquids and suspensions is such that where infrared spectra of dried samples are generated and evaluated using a multivariate evaluation procedure. In the evaluation procedure, the samples to be analyzed are assigned to classes. The evaluation procedure is trained with samples of known classes to adjust the parameters of the evaluation procedures such that samples of unknown classification can be assigned to known classes. In an advantageous manner, the infrared spectra can be generated by a transmittance measurement on a dried film of the sample.

Abstract: The present invention provides apparatus and methods for determining the concentration of sample components of a sample by an analytical technique that yields a spectrum that can be written as Y(.omega.)=P(.omega.).multidot.C. The apparatus and methods of the invention account for experimental errors that give rise to distortions in the observed spectrum and that consequently result in inaccurate determinations of sample component concentrations. The invention accounts for such errors by modeling the total experimental error as the sum of one or more types of errors that can be written as .xi..multidot.K. The spectrum is then modeled as Y=P.multidot.C+.xi..multidot.K. Using the observed spectrum, known values for P, and a mathematical model for .xi., this equation can be solved for the best fit value of the sample component concentrations, C, and the magnitudes of the errors, K. The method can be used for any error that can be modeled in the foregoing manner, such as a shift in the spectrum.
