摘要： In a colloboration system which allows a plurality of programs to interact, each program registers an "interest" in messages with a session object. The session object, which represents the colloboration session and acts as a collaboration manager, receives all messages but broadcasts a received message only to those programs which have registered an interest in the message. In one embodiment, a colloborative application framework is used to build both the session object and the application programs. The framework includes class code information which is incorporated into each application program by subclassing and which allows each program to communicate with the session object through a predetermined protocol.

摘要： A collaborative application framework is used to build application programs which communicate with a central collaboration manager by means of a predetermined protocol. The predetermined protocol allows converters to be located at the collaboration manager site so that the programs neither include, nor require, preconfigured converters. Accordingly, new programs may easily and inexpensively be added to the system. The framework includes class code information which is incorporated into each application program by subclassing and which allows the program to communicate with the central manager by passing messages. The framework further includes class code for creating in the central manager a session object which receives a first message from a first program, converts the information in the first message into an information format utilized by a second program and forward a second messages to the second program containing information in the appropriate format. Since the converting mechanism is a part of a session object, it is not incorporated into first and second programs.

摘要： A collaborative session is represented by a session object which receives all messages generated by the programs and transmits the messages to all programs participating in the session. The session object can include shared objects which are managed by the session and can be updated without requiring messages to be transmitted over a network. Accordingly, programs may enter a session after it begins and immediately access common session information, such as a state database.

摘要翻译： 协作会话由会话对象表示，会话对象接收由节目生成的所有消息，并将消息发送给参与会话的所有节目。 会话对象可以包括由会话管理的共享对象，并且可以更新，而不需要通过网络传输消息。 因此，程序可以在其开始之后进入会话并立即访问公共会话信息，诸如状态数据库。

摘要： A method is disclosed for modeling and processing an asynchronous functional specification to provide an input to an architecture synthesis engine. The method includes the step of generating an initial task graph from the specification, the task graph having a number of executable tasks. Selected data and control connections are established between respective tasks in accordance with a specified set of rules to define some of the tasks to be deterministic, and other of the tasks to be non-deterministic. Each of the control connections is then marked, to provide an annotated task graph for use as an input to the architecture synthesis engine, the annotated task graph enabling the engine to employ specified scheduling techniques.

摘要： A field programmable gate array has antifuses disposed over logic modules. Each of these antifuses includes a conductive plug and an overlaying region of programmable material (for example, amorphous silicon). To program one of these antifuses, an electric connection is formed through the programmable material to couple the conductive plug to a metal conductor that overlays the region of programmable material. The metal conductor includes a layer of a barrier metal to separate another metal of the conductor (for example, aluminum from an aluminum layer) from migrating into the programmable material when the antifuse is unprogrammed. In some embodiments, less than three percent of all antifuses of the field programmable gate array has a corner (from the top-down perspective) of the region of programmable material that is disposed (within lateral distance DIS of the conductive plug) underneath the metal conductor of that antifuse. In some embodiments, less than seventy-five percent of all antifuses of the field programmable gate array have an edge of the region of programmable material disposed (within lateral distance DIS of the conductive plug) underneath the metal conductor of that antifuse. Other antifuse structures and methods are also disclosed for preventing programmable material corners and/or edges from compromising yield and/or reliability of programmable devices.

摘要： A method for rendering two-dimensional shapes and two-dimensional projections of three-dimensional shapes on a projection plane uses a sorting table to determine which shapes overlap other shapes. For each two-dimensional shape, the shorting table includes an order attribute specifying the front to back ordering of the two-dimensional shapes on the projection plane. For each three-dimensional shape the sorting table includes a Z-value specifying a position along a coordinate perpendicular to the projection plane. The position specified is dependent on whether the three-dimensional shape is perceived to be in front of the projection plane or behind the projection plane. The values in the sorting table are sorted to produce a composite ordering of the shapes and a drawing is created by sequentially rendering each shape in the composite order of the sorting table to depict an overlapped appearance of the shapes.

摘要： An antifuse, which has a programmable material disposed between two conductive elements, is programmed using multiple current pulses of opposite polarity. The first pulse has a current that is insufficient to fully program the antifuse, i.e., produce a desired level of resistance. In one embodiment the first pulse is current limited. The first pulse advantageously drives a conductive filament from one conductive element through the antifuse material, which may be, e.g., amorphous silicon. The conductive filament from the first pulse, however, has a limited cross sectional area. A programming pulse having the same voltage with opposite polarity and a current with increased magnitude is used to drive material from the other conductive element into the antifuse material, which increases the cross sectional area of the conductive filament thereby reducing resistance. Additional programming pulses, as well as current limited pulses, may be used if desired. Programming an antifuse in accordance with the present invention results in an antifuse structure with a conductive filament that is in good contact with both conductive elements, which reduces resistance in the antifuse and increases yield. A programming circuitry is provided that includes a current source and a voltage clamp to program antifuses according the described method.

摘要： A metal-to-metal conductive plug-type antifuse has a conductive plug disposed in an opening in an insulating layer. A programmable material feature (for example, amorphous silicon) overlies the conductive plug. A conductor involving a metal (for example, aluminum or copper) that migrates in the programmable material overlies the programmable material. To prevent migration of metal from the conductor into the programmable material when the antifuse is not programmed, the conductor has a layer of barrier metal between the metal that migrates and the programmable material. In some embodiments, there are two layers of barrier metal. An airbreak after formation of the first barrier metal layer improves the ability of the barrier metal to prevent diffusion between the programmable material and the overlying conductor. The airbreak may stuff grain boundaries in the upper surface of the first barrier metal and/or may cause the first barrier metal layer to have different grains and/or a different grain orientation than the overlaying second barrier metal layer. In some embodiments, a capping layer over the top surface of the programmable material protects the underlying programmable material during an ashing step when a mask used to etch the programmable material is removed. The capping layer and the programmable material form a capping layer/programmable material layer stack within the antifuse underneath the two barrier metal layers. The capping layer may also be made of a barrier metal and constitute an additional barrier.
