  • Patent number: 8041553
    Abstract: A computer-based system for testing a circuit design for implementation within an integrated circuit device can include a design application (205) providing simulation instructions for testing a circuit design and a simulation driver (225) receiving the simulation instructions and translating the simulation instructions into control protocol instructions specifying operations of an integrated circuit control protocol. The system can include a simulation environment (240). The simulation environment can include a communication module (245) communicating with the simulation driver, a simulation cable driver (250) receiving the control protocol instructions from the simulation driver via the communication module, and a control module (255). The simulation cable driver further can translate the control protocol instructions into signaling information corresponding to the integrated circuit control protocol.

  • Patent number: 7184946
    Abstract: Method and apparatus for interfacing a high-level modeling system (HLMS) with a reconfigurable hardware platform for co-simulation. In one embodiment a boundary-scan interface is coupled to the HLMS and is configured to translate HLMS-issued commands to signals generally compliant with a boundary-scan protocol, and translate signals generally compliant with a boundary-scan protocol to data compatible with the HLMS. A translator and a wrapper are implemented for configuration of the hardware platform. The translator translates between signals that generally compliant with the boundary-scan protocol and signals that are compliant with a second protocol. A component to be co-simulated is instantiated within the wrapper, and the wrapper transfers signals between the translator and the component.
