    • According to an embodiment of the invention, a system for identifying when a running speed of an integrated circuit is within an applied clock speed is provided. A monotonic circuit is configured to receive input data and transmit output data. A completion detection circuit is configured to generate a completion detection signal for the monotonic circuit. A comparator is configured to compare at least the completion detection signal and a clock signal, and configured to emit an error signal if the clock signal arrives before the completion detection signal. A synchronous circuit element is configured to receive at least a portion of the output data and configured to be clock driven by the clock signal. The error signal represents that the clock speed is faster than an operating speed of the monotonic circuit.
    • 根据本发明的实施例,提供了一种用于识别集成电路的运行速度何时处于施加的时钟速度内的系统。 单调电路被配置为接收输入数据并发送输出数据。 完成检测电路被配置为产生用于单调电路的完成检测信号。 比较器被配置为至少比较完成检测信号和时钟信号,并且如果时钟信号在完成检测信号之前到达则被配置为发出错误信号。 同步电路元件被配置为接收输出数据的至少一部分并被配置为由时钟信号驱动时钟。 误差信号表示时钟速度比单调电路的运行速度快。
