摘要： Routing systems and methods are provided having various strategies for optimizing and evaluating possible routes for netlist connections. In one embodiment, a data structure or matrix provides cost related data weighted to evaluate the impact proposed a connection or segment will have upon an attribute of interest such as, for example, speed, manufacturability or noise tolerance. This cost information can be related to terrain costs as well as shape costs to provide multidimensional cost information for connections. Processing such higher information cost data is made more efficient with an additive process that is less demanding than a computationally intensive iterative multiplication process. Various methods are also disclosed for shifting and adjusting routing grids to improve use of available space or reduce run time in routing. In another embodiment, a parallel processing scheme is used to process multiple regions on multiple processors simultaneously without creating conflicts, that could arise, for example, when two processors try to route a trace on the same gridpoint.

摘要： A system that facilitates generating a global routing for a layout of an integrated circuit operates by receiving a netlist to be routed. The system partitions this netlist into global signals, datapath signals, and control signals. Next, the system creates a tiling grid of the integrated circuit and routes connection nets between tiles within this grid. The system then selects an area within the integrated circuit larger than a tile in the first grid. The system creates a second grid of tiles smaller than the tiles of the first grid within this selected area. During this process, connection nets are routed between tiles on the second grid while routings within the first grid are maintained. The system merges connection nets within the first grid with connection nets within the second grid to form the global routing.

摘要： Multi-chassis fabric-backplane enterprise servers include a plurality of chassis managed collectively to form one or more provisioned servers. A central client coordinates gathering of provisioning and management information from the chassis, and arranges for distribution of control information to the chassis. One of the chassis may perform as a host or proxy with respect to information and control communication between the client and the chassis. Server provisioning and management information and commands move throughout the chassis via an Open Shortest Path First (OSPF) protocol. Alternatively, the client may establish individual communication with a subset of the chassis, and directly communicate with chassis in the subset. Server provisioning and management information includes events generated when module status changes, such as when a module is inserted and becomes available, and when a module fails and is no longer available. Each chassis includes a switch fabric enabling communication between chassis modules.

摘要： Pluggable modules communicate via a switch fabric dataplane accessible via a backplane. Various embodiments are comprised of varying numbers and arrangements of the pluggable modules in accordance with a system architecture that provides for provisioning virtual servers and clusters of servers from underlying hardware and software resources. The system architecture is a unifying solution for applications requiring a combination of computation and networking performance. Resources may be pooled, scaled, and reclaimed dynamically for new purposes as requirements change, using dynamic reconfiguration of virtual computing and communication hardware and software.
