Methods and apparatuses to optimize a circuit representation using unfolding as a preprocessing of the multirate folding. In at least one embodiment of the present invention, a portion of a data flow graph representation of a circuit is optimized using circuit operation level before using optimizing with data flow algorithm and mapping the design onto hardware. In an aspect, the present invention discloses circuit operation level optimization for data flow graph representations with optimizing zero inputs caused by the upsamplers, or with optimizing unused outputs caused by the downsamplers. In at least one embodiment of the present invention, multirate data graph is converted to a single rate data graph before data flow optimizing. In an aspect, converting a multirate data graph to a single rate data graph comprises unfolding the multirate data graph with minimum unfolding factors that are inversely proportional to the clock values.

One embodiment of the present invention provides a system for facilitating floorplanning for three-dimensional integrated circuits (3D ICs). During operation, the system receives a number of circuit blocks. The system places the blocks in at least one layer of a multi-layer die structure and sets an initial value of a time-varying parameter. The system then iteratively perturbs the block arrangement until the time-varying parameter reaches a pre-determined value.

A system, method, and computer program product for automated creation of collision-free paths for pipes and tubes in a CAD system. A method includes receiving inputs, in a data processing system, defining at least a start point and destination point for a pipe in a CAD environment, and a diameter for the pipe. The method includes determining sample points between the start point and destination point. The method also includes building a graph including the sample points and the start point and the destination points as nodes and a plurality of edges connecting the nodes. The method also includes computing a path through the graph between the start point and the destination point. The method also includes, for each node in the path, testing each edge connected to the node to determine if there is a collision along the edge between a test object model and a background model geometry in the CAD environment, and removing from the graph any edge that has a collision. If there is no collision along an edge of the path, then designating the path as a successful path and displaying the successful path to a user by the data processing system.

A power optimization method of deriving gated circuitry in a synthesized netlist of an integrated circuit (IC) design is provided. A block in the synthesized netlist is identified as an idle candidate block. Sub-blocks on the chip are clustered into a cluster. For the cluster, a clock gating structure optimized for power savings is determined, based on the idle candidate block. One or more inflexible clock gates are inserted in the netlist according to the clock gate structure.

To tackle the increasing communication complexity of multi-core systems, scalable Networks on Chips (NoCs) are needed to interconnect the processor, memory and hardware cores of the systems. For the use of NoCs to be feasible in today's industrial designs, a custom-tailored, application-specific architecture that satisfies the objectives and constraints of the targeted application domain is required. In this work we present a method for synthesizing such application-specific NoC architectures. This best topology is achieved by a method to design Networks on Chips (NoCs)-based communication system for connecting on-chip components in a multicore system, said system comprising several elements such as processors, hardware blocks, memories, communicating through the communication system, said communication system comprising at least switches, said method comprising the steps of: - obtaining predefined communication characteristics modelling the applications running on the multicore system, - establishing the number and configuration of switches to connect the elements, - establishing physical connectivity between the elements and the switches, - for each of at least two pairs of communicating elements : a defining a communication path, that is, a sequence of switches to be traversed to connect the aforementioned pair of communicating elements, b calculating metrics as affected by the need to render said path into physical connectivity, said metrics being selected among one or a combination of power consumption of the involved switches, area of the involved switches, number of inputs and outputs of the involved switches, total length of wires used, maximum possible speed of operation of the system and number of switches to be traversed, taking into account any previously defined physical connectivity, c iterating the steps a and b for a plurality of possible paths, d choosing the path having the optimal metrics, e establishing any missing physical connectivity between the switches so that the selected optimal path occurs across physically connected switches.
