Abstract: An emulation process is performed with an emulator coupled to one or more targets. During a part or a whole of the emulation process, input signals to the emulator from the one or more targets are being captured, streamed out of the emulator and stored in one or more processor-readable media. The part or the whole of the emulation process is then repeated with the emulator decoupled to the one or more targets. During the repeating, the input signals stored in the one or more processor-readable media are being streamed back to the emulator. The streaming in both of the capture and replay modes may be through interfaces designed for small packets of data and fast streaming speed.

Abstract: Aspects of the invention relate to techniques for dynamic control of design clock generation in emulation. A circuit design for verification is analyzed to determine one or more clock-enabling functions for a specific clock signal. Logic for generating a clock status signal based on the one or more clock-enabling signals is then determined. The clock status signal is employed to control clock generation in an emulation system for emulating the circuit design.

Abstract: Aspects of the invention relate to techniques for adaptive clock management in emulation. A clock suspension request signal, indicating when a suspension of design clock signals in an emulator is needed, is generated based on activity status information of the emulator with one or more emulator resources such as software environment. A clock suspension allowance signal, indicating whether a suspension of design clock signals is permitted considering dynamic targets in the emulator, is generated based on slack information related to one or more clock signals associated with one or more dynamic targets of the emulator. Based on the clock suspension request signal and the clock suspension allowance signal, a clock suspension signal is generated for enabling temporary design clock suspensions.
