  • Patent number: 11281834
    Abstract: Approaches for protection of HLL simulation models in a circuit design having unprotected high-level language (HLL) program code and first metadata of a shared library of executable simulation models that are based on sensitive HLL simulation models. A design tool determines a first storage location of the shared library based on the first metadata and compiles the unprotected HLL program code into an executable object. The design tool links the executable object with the library of executable simulation models from the first storage location and then simulates the circuit design by executing the executable object and loading the executable simulation models in response to initiation by the executable object.

  • Patent number: 10893005
    Abstract: Examples described herein provide for an electronic circuit, such as a System-on-Chip (SoC), having a Network-on-Chip (NoC). The NoC is configurable and has capabilities to be partially reconfigured. In an example, a NoC on an integrated circuit is configured. Subsystems on the integrated circuit communicate via the NoC. The NoC is partially reconfigured. A first subset of the NoC is reconfigured during the partial reconfiguration, and a second subset of the NoC is capable of continuing to pass communications uninterruptedly during the partial reconfiguration. After the partial reconfiguration, two or more of the subsystems communicate via the first subset of the NoC.

  • Patent number: 8020124
    Abstract: Various methods and apparatuses are described for generating a model of hardware components making up an interconnect that facilitates communications between Intellectual Property blocks in an integrated circuit coded in a software programming language at a high level of abstraction that is cycle accurate to a corresponding lower level of abstraction description of the hardware components making up the interconnect. The sub-components of the model at the high level of abstraction are tested in a simulation environment in parallel with the same sub-components of a model coded in a hardware description language at the low level of abstraction in order to verify the functional accuracy and cycle timing between the two models. After the sub-components are tested, the sub-components of the model at the high level of abstraction may be aggregated into a single model at the high level of abstraction that is functionally accurate and cycle accurate to the model at the low level of abstraction.

  • Publication number: 20050021305
    Abstract: Various methods and apparatuses are described in which a software programming interface connects one or more functional checker components and one or more protocol checker components to an interconnect monitor component. A computer readable medium stores code for the one or more functional checker components for Intellectual Property (IP) cores, one or more protocol checker components, the interconnect monitor component, and the software programming interface. The monitor component has code to build data structures containing protocol data types requested by a checker component and code on where to deliver data based upon a particular type of data requested by the checker component.
