Abstract: Electrical contacts with a reduced section for use in high-voltage switches, the contacts are produced by machining or by extrusion. The contacts are designed to be used outdoors, indoors, in vacuum or in any other inert atmosphere for electrical switching equipment without additional pressure system or with additional pressure system. The contacts can be used in linear movement, radial movement, or any other type of movement or sliding. The contacts can be used in various shapes, such as contact pins or tulip shapes, partial tulips, or rectangular tulips, or they can be used as the single pressure element for the electrical contact. The contacts are designed to cooperate electrically with opposing contact parts. The contacts can interrupt a physical link with an opposing contact or they can remain in constant contact during the operating movement. The contacts are made from aluminum alloys, with or without contact surfaces. A contact assembly can use the same base materials or different base materials.

Abstract: A high-voltage disconnection knife insulated by air for external use in high-voltage electrical transmission and distribution networks, the disconnection knife includes two copper arms for the disconnection or contact, mounted in a parallel relation to each other, a front and rear contact base, a turning support in the vicinity of the rear base such that the arms turn at one of its ends about an axis perpendicular to them, a central copper block for distribution of the current flowing through the copper arms; the distance between the arms is defined by the set of stainless steel axes, the copper block and the turning mechanism. At the ends of the disconnection arms an aluminum spring of with transverse section of gradually reduced thickness is connected to the external surface, said spring being fixed to the ends of the arms by means of a pair of stainless steel axes. The front and rear L-shaped bases are formed by the bending of a copper sill with rounded edges to define an area of contact.

Abstract: A layout of a standard cell is created by prioritizing routability characteristics of the standard cell layout. The routability characteristics are prioritized so that the characteristics that are more likely to enhance routing efficiency are emphasized in the cell layout. The prioritization of the routability characteristics can be indicated by a set of weights, with each weight in the set indicating the priority of a corresponding routability characteristic of the standard cell layout. The weights can be used to calculate a weighted sum of the routability characteristics of the standard cell, thereby providing a way to efficiently compare the routability of different standard cell layouts.

Abstract: A critical path minimization technique uses a novel reshaping layout reorganization mechanism. Circuit objects and/or object fragments which belong to a critical path in a reference direction are reshaped using resources of an orthogonal direction. A fragment may decrease its size in the layout in the reference direction and increase its size in the orthogonal direction. Types of reshaping include via, diode or tie reshaping, transistor chain reshaping by transistor finger resizing, and transistor chain reshaping by transistor finger removing. The removal technique can include removal of one (or 2N+1) transistor finger(s) from an edge (e.g., beginning or end) of a transistor chain, removal of two (or 2N) adjacent transistor fingers from any position of a transistor chain, removal of one (or 2N+1) transistor finger(s) from inside a transistor chain with diffusion gap insertion, and removal of a group or series of transistor fingers.

Abstract: A channel routing method (200) comprises computing channel parameters (210), classifying a channel complexity and estimating a channel height (220), optionally, determining a trunk placement direction (225), assigning tracks and layers (230), determining a quality function QF (240), and optimizing (250). The channel complexity is classified using predetermined weighting parameters (a1 to a4). This classification selects a significance vector n. In the assigning step (230), the vector n is combined with the channel parameters to a criterion. The criterion is used the select the most suitable assignment. In repetitions of assigning, determining QF and optimizing steps, the significance vector n and, optionally, QF are modified. The repetition are stopped upon compliance of a breaking condition which can refer to QF.

Abstract: The invention concerns a method for manufacturing an electronic device having a channel. The channel has a number of rows and columns for wiring of nets. Usually each wiring layer is dedicated to either the rows or the columns. According to this method certain row segments can be shifted from one wiring layer to another, so that the channel area is used more effectively.

Abstract: The present layout compaction technique compacts circuit elements in two dimensions of a circuit layout with reduced computational requirements. A circuit layout representation is converted to a constraint graph representation in a reference direction. An orthogonal constraint graph is also constructed. A critical path subgraph is constructed based upon the reference and orthogonal constraint graphs, where one or more critical paths are chosen as the longest paths between the source and sink vertices of the reference constraint graph. Further, each vertex in the constraint graph is converted to an input vertex for each incoming shear edge and an output vertex for each outgoing shear edge. Jogging edges are created between each input and output vertices in the critical path subgraph. Weight values are assigned to each shear and jogging edge.
