A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp. For example, a subway map intended for passengers may represent a subway station with a dot. The dot is not intended to resemble the actual station at all; instead, it aims to give the viewer information without unnecessary visual clutter. A schematic diagram of a chemical process uses symbols in place of detailed representations of the vessels, piping, valves, pumps, and other equipment that compose the system; in so doing, it emphasizes the functions of these individual elements--and the interconnections among them--and suppresses their particular physical details. In an electronic circuit diagram, the layout of the symbols may not look anything like the circuit as it appears in the physical world: instead of representing the way the circuit looks, the schematic aims to capture, on a more general level, the way it works.

Automatic schematic diagram generation using topology information

A netlist of a schematic diagram is generated. The netlist indicates the connectivity of components through connection lines. A normal display mode is provided in which at least a portion of the components are presented on the display, and connection lines corresponding to the components are also displayed. A topology display mode is provided in which the components are presented on the display without the connection lines. The user can switch between the topology display mode and the normal display mode while editing the schematic diagram. Automatic pin assignment and routing of the connection lines is performed according to the netlist, and is based upon grouping similarly classified connection lines. An abstract display mode is provided that presents abstract lines for a selected component, with a single abstract line running between two connected components. The abstract display mode is combinable with the topology display mode. Finally, the automatic positioning of components according to predefined topology templates is provided.

Dual-Beam Sector Antenna and Array

A low sidelobe beam forming method and dual-beam antenna schematic are disclosed, which may preferably be used for 3-sector and 6-sector cellular communication system. Complete antenna combines 2-, 3- or -4 columns dual-beam sub-arrays (modules) with improved beam-forming network (BFN). The modules may be used as part of an array, or as an independent 2-beam antenna. By integrating different types of modules to form a complete array, the present invention provides an improved dual-beam antenna with improved azimuth sidelobe suppression in a wide frequency band of operation, with improved coverage of a desired cellular sector and with less interference being created with other cells. Advantageously, a better cell efficiency is realized with up to 95% of the radiated power being directed in a desired cellular sector.

HPLC schematic with integrated sample cleaning system

The disclosed HPLC flow schematic back-flushes the guard column with mobile phase once every operating cycle, the regular cleaning maintaining its effectiveness and useful life. This mobile phase flow reversal is accomplished by imposing a two position multiple port switching valve between the guard and separation columns. In one valve position, the mobile phase is pumped in one flow direction through both the separation and guard columns, but the switched valve maintains the same flow direction only through the separation column and reverses the mobile phase flow direction through the guard column, for effectively cleaning the guard column. Moreover, the mobile phase back flow is directed over the emptied sample drawing needle for cleaning it to reduce possible sample cross contamination. The improved flow circuits use basically only the typical HPLC system components, except for some insignificant modifications from existing injector designs.

System and method for automatic mesh generation from a system-level MEMS design

A mesh generation tool that is programmatically integrated with a system-level design and simulation environment, thereby enabling the direct generation of PDE solver input from a system-level design and simulation environment and a method for using the mesh generation tool are disclosed. Automatic mesh generation and optimization is improved by making available additional information about the nature and purpose of certain design components to the mesh generation tool. Specifically, the parameters of the components in the device schematic, which represent a user-defined decomposition of a larger MEMS design into smaller entities of clear physical purpose, are made available to the mesh generation tool. The link established between the system-level design and PDE analyses allows the user to move between the two levels of abstraction. The mesh generation tool retrieves information from the components and connectors of a schematic of a MEMS device, and produces a discrete element model suitable for numerical PDE analysis by the finite element (FEM) and boundary element (BEM) methods. A direct link from a schematic model to a mesh model helps the user to produce an optimal mesh for PDE analysis, thereby avoiding considerable unnecessary computation.

Technique for modeling parasitics from layout during circuit design and for parasitic aware circuit design using modes of varying accuracy

Techniques are presented for accounting for parasitics in the automated design of integrated circuits. In one set of techniques, model values for parasitic models are received on a schematic environment from a user, the parasitic models are evaluated from the schematic using the received model values, the parasitic models are transferred to a layout environment, and the transferred parasitic models are evaluated on the layout environment. In other techniques, model values are received for parasitic models from a user, the parasitic models are evaluated on the layout environment, and the process then backannotates the parasitic models evaluated on the layout environment and corresponding parameter values to a schematic environment. In yet other techniques, a user is presented with a simulation environment within which the user is provided a choice to select between parasitic simulation modes of varying accuracy, the modes including a mode without parasitics and a plurality of modes including parasitics with a varying degree of accuracy. A selection from among the modes is received from the user and simulation test are performed at the selected degree of accuracy.
