Adaptive Clock Management In Emulation

摘要

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.

1. A method, comprising:
synthesizing logic that can generate a clock suspension request signal based on activity status information of an emulator with one or more emulator resources; synthesizing logic that can generate a clock suspension allowance signal based on slack information related to speed constraints of one or more clock signals associated with one or more dynamic targets of the emulator and; and synthesizing logic that can generate a clock suspension signal for enabling temporary suspensions of design clock signals in the emulator based on the clock suspension request signal and the clock suspension allowance signal.
