Detailed Description

The class CLKDevice is used to consistently distribute clock/timing and reset amongst all IPs of the library. Devices that inherit from CLKDevice receive two SignalKit inputs: clk and rst. If the child requires reset behavior, it may implement the virtual function dorst(), which is triggered by the rst input. Moreover, CLKDevice provides a data member „clock_cycle“, which can be used by the child to determine the clock period for delay calculations. The value of clock_cycle is set by connecting a sc_time SignalKit signal to the clk input or by calling one of the various set_clk functions of the class.
