  • Methods and apparatus for buffered assertion reporting in emulation
    Patent number: 11475192
    Abstract: Systems and methods for IC chip design testing can include a hardware emulator, having circuitry to emulate functionalities of an integrated circuit chip design and a buffer, detecting an assertion failure event indicative of a failed assertion on one of the functionalities, and storing a message indicative of the assertion failure event in the buffer. The circuitry can transfer, asynchronously relative to execution of the hardware emulator, the message from the buffer to a software host device without halting the execution of the hardware emulator. The software host device can receive the message indicative of the assertion failure event, and execute, asynchronously relative to the execution of the hardware emulator, at least one fail action instruction associated with the assertion failure event.
