  • Self-checking simulations using dynamic data loading
    Patent number: 7606695
    Abstract: A system for evaluating a simulation includes a reference simulator configured to execute a simulation image to obtain golden data, a test simulator configured to execute the simulation image to obtain test data, and a comparator configured to generate a comparison result by comparing a portion of the golden data to a portion of the test data before the execution of the simulation image on the test simulator has completed.
    Type: Grant

  • Method and apparatus for generating minimal node data and dynamic assertions for a simulation
    Patent number: 7236917
    Abstract: A system for tracing a simulation design involves an encoded assertion asserting a value of a node of the simulation design at a point in a simulation, a fanin cone detection facility configured to obtain a fanin cone for the encoded assertion, a waveform trace facility configured to obtain waveform data including a history of signal values for the node, and a simulation toolkit configured to obtain node data using the fanin cone and the waveform data.

  • System and method for efficiently tracing simulation data in hardware acceleration simulation systems
    Patent number: 7162403
    Abstract: A system for tracing signals for a cycle-based simulation includes a traced signal and a system resources availability information of the cycle-based simulation, a runtime compiler configured to use the system resources availability information to assign a system resource to trace the traced signal, a logic design used with the system resources availability information to generate a simulation image, a first value of the traced signal generated by execution of a simulation image, and a traced signal buffer configured to store the first value and upload the first value.
