摘要
A method of configuring a configurable logic system, including a single or multi-FPGA network, is disclosed in which an internal clock signal is defined that has a higher frequency than timing signals the system receives from the environment in which it is operating. The frequency can be at least ten times higher than a frequency of the environmental timing signals. The logic system is configured to have a controller that coordinates operation of its logic operation in response to the internal clock signal and environmental timing signals. Specifically, the controller is a finite state machine that provides control signals to sequential logic elements such as flip-flops. The logic elements are clocked by the internal clock signal. In the past, emulation or simulation devices, for example, operated in response to timing signals from the environment. A new internal clock signal, invisible to the environment, rather than the timing signals is used to control the internal operations of the devices. Additionally, a specific set of transformations are disclosed that enable the conversion of a digital circuit design with an arbitrary clocking methodology into a single clock synchronous circuit.
