  • Publication number: 20230098098
    Abstract: Using scalable scribe regions for implementing a user circuit design includes generating a scribe region having a plurality of contours for a static top design of a circuit design for an integrated circuit. The static top design is configured to integrate with a user circuit design in the integrated circuit. Each contour defines a different size of the scribe region having a boundary that extends outward in at least one direction from a boundary of a floorplan area of the static top design on the IC. The scribe region can be translated into design constraints defining the plurality of contours of the scribe region and restrict placement of components of the user circuit design within the scribe region as sized according to a selected contour. The static top design and the plurality of design constraints can be stored in a memory for use in implementing the user circuit design.

  • Patent number: 11204747
    Abstract: Embodiments herein describe techniques for interfacing a neural network application with a neural network accelerator that operate on two heterogeneous computing systems. For example, the neural network application may execute on a central processing unit (CPU) in a computing system while the neural network accelerator executes on a FPGA. As a result, when moving a software-hardware boundary between the two heterogeneous systems, changes may be made to both the neural network application (using software code) and to the accelerator (using RTL). The embodiments herein describe a software defined approach where shared interface code is used to express both sides of the interface between the two heterogeneous systems in a single abstraction (e.g., a software class).

  • Patent number: 10802995
    Abstract: A system may include a host processor coupled to a communication bus, a first hardware accelerator communicatively linked to the host processor through the communication bus, and a second hardware accelerator communicatively linked to the host processor through the communication bus. The first hardware accelerator and the second hardware accelerator are directly coupled through an accelerator link independent of the communication bus. The host processor is configured to initiate a data transfer between the first hardware accelerator and the second hardware accelerator directly through the accelerator link.

  • Patent number: 8769449
    Abstract: Methods for generating a circuit design are disclosed. A plurality of cells is instantiated in the circuit design in response to user input. The set of interface parameters of each cell is arranged into a hierarchy of interface levels as indicated by an interface model corresponding to the cell. For each of the interface levels, values of the sets of interface parameters of cells included in the interface level are respectively propagated to other cells directly connected to the cell. In response to propagating a value of an interface parameter from another cell of the plurality of cells to the cell and the cell having a value of the corresponding interface parameter that is different from the propagated value, a value for the corresponding interface parameter of the cell is determined using a respective propagation function associated with the corresponding interface level.

  • Patent number: 6470961
    Abstract: A condenser, radiator and fan assembly module for providing modular installation and simplified individual servicing of the components thereof. The module includes a condenser, a radiator, a fan assembly, and a module frame having a set of channels for respectively receiving therein each of the condenser, radiator and fan assembly. Each of the condenser, the radiator and the fan assembly are slidably received into its respective channel. A floor of the module frame may be disassembled to facilitate individual sliding removal of any of the condenser, radiator or fan assembly. To facilitate sliding installation and removal of the radiator, the coolant inlet fitting and the coolant outlet fitting are each threadably engaged into a respective threaded opening in the tank of the radiator.

  • Patent number: 6217427
    Abstract: A tool for the linear polishing of substrates includes an endless belt of continuous strength wrapped substantially as a helix of predetermined length and width with a 180 degree twist along the length to increase by a factor of 2× the time interval between which belt changes need to be made because of wear-and-tear, significantly reducing the costs associated with the polishing because of reduced down time. In a preferred embodiment for the chemical-mechanical polishing of silicon wafer substrates used in fabricating integrated circuits, the endless belt is constructed as a Mobius strip of a rubberized, urethane composition to be flexible, but yet strong enough to withstand the applied pressure between the polishing belt and the substrate.

  • Patent number: 5008217
    Abstract: Direct contact to shallow junctions in integrated circuits and interconnection between these contacts is achievable by utilizing a specific aluminum CVD process. In this process the aluminum is deposited utilizing a triisobutyl aluminum precursor onto a substrate having a nucleation layer, e.g. a titanium nitride layer. By appropriate choice of this nucleation layer to control the nucleation of the depositing aluminum, suitable contact is made while avoiding void defects present in the absence of such layer.
