摘要:
A technique will automatically route interconnect of an integrated circuit while taking into consideration current density rules. In an implementation, the technique uses a shape-based approach where a grid is not used. Based on data input including current density and a frequency of each net, the technique will determine the current requirements for each net. In an implementation, the technique forms a Steiner tree for a net, and routs using the Steiner tree. The technique widens nets having greater current requirements; adjacent wiring may be pushed aside to create sufficient space for wider nets.

A technique will automatically route interconnect of an integrated circuit and adjust spacing between tracks or interconnect in order to improve performance or reduce electromigration effects. By increasing spacing between certain tracks or moving tracks, performance can improve because a track will be more noise immunity from nearby tracks on the same layer or on different layers. The automatic router will adjust spacing between tracks depending on one or more factors. These factors may include current associated with a track, width of a track, capacitance, inductance, and electromigration. In a specific implementation, the technique uses a shape-based approach where a grid is not used. The technique may further vary the width of the tracks.

The present subject matter is directed to an apparatus and methodology for detecting three-way call attempts during telephone conversations. Per the methodology, apparatus is configured to, in effect, “ping” a called telephone by transmitting an audio frequency range tone over the loop established from the calling telephone to the called telephone, measuring the tone return time and using that measurement as a base measurement comparison point for additional measurements during the course of a conversation. The base measurement would be inherently determined by the particular path established for a given call, which path does not ordinarily change during the call. If the return time for a subsequent measurement deviates significantly from the base measurement, a determination is made that a three-way call attempt has been made because it would be a strong indicator that the total path of the call had changed, which would only occur if the inherent nature of the call changed (i.e., became a three-way call).

A method for operating with multiple protocols for handling communications comprising the steps of obtaining information from sensors and related input devices utilizing specialized tamper resistant passive transceivers working with active pulse type transceivers to create historical maps of information on people or objects. This includes steps of: a) identifying recording information, b) sending and receiving prompts, c) associating the call with timers, d) monitoring passive transceivers with low level diagnostic information, e) monitoring the transceivers with voice recognition software, f) recording associated data, g) identifying the users, the key words or phrases within the recorded data, h) naming the recording and i) saving the data in a protected format.
摘要:
A system automatically routes interconnect of an integrated circuit design using variable width interconnect lines. For example, a first automatically routed interconnect may have a different width from a second automatically routed interconnect. The system will vary the width of the interconnect lines based on certain factors or criteria. These factors include current or power handling, reliability, electromigration, voltage drops, self-heating, optical proximity effects, or other factors, or combinations of these factors. The system may use a gridded or a gridless (or shape-based) approach.

A method and technique of routing interconnects of an integrated circuit providing improved routing quality. In an embodiment of the invention, the technique provides linear spine interconnect routing. In memory array blocks, such as in DRAM and SRAM memory designs, connected pins are generally separated by large distances in a first direction and small distances in a second direction, or a spine or channel region. A route area is defined within the spine region. In one embodiment, obstacles in the route area are identified and corresponding forbidden areas are demarcated. The linear spine interconnect is routed in the first direction within the route area while avoiding the forbidden areas. Pins are connected to the spine interconnect by stitching interconnects. Stitching interconnects are generally routed in the second direction.
