Patents by Inventor Subha S. Chowdhury

Subha S. Chowdhury has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9536027
    Abstract: One embodiment of the present invention provides systems and techniques to execute a hardware simulation and verification solution on a multiprocessor system. The hardware simulation and verification solution can be partitioned into different modules which can include a simulation kernel to simulate changes in signal values, a value change dump module to store the changes in the signal values on a computer-readable storage medium, a functional coverage module to check functionality, a toggle coverage module to check signal toggling, an assertion engine to check complex behaviors, and a testbench module to generate test scenarios. Embodiments of the present invention can execute different modules on different processors, thereby improving performance.
    Type: Grant
