1. An electronic circuit comprising:
digital circuits, each digital circuit of the digital circuits having a respective clock input; and
adaptive clock generator circuitry having generator clock outputs, each respective clock input coupled to one of the generator clock outputs, and the adaptive clock generator circuitry including:
a processor having an input interface and an output interface, the processor configured to provide resource configuration parameters at the output interface in response to clock settings received at the input interface and target settings; and
clock generator resources having a control input, a root clock input, and resource clock outputs, the control input coupled to the output interface, each resource clock output of the resource clock outputs coupled to a respective generator clock output of the generator clock outputs, and the clock generator resources configured to provide a respective clock signal at each of the resource clock outputs in response to the resource configuration parameters received at the control input, wherein the control input is a first control input, and the adaptive clock generator circuitry includes a setting detection circuit having second and third control inputs and first and second setting outputs, the setting detection circuit configured to provide clock settings at the first and second setting outputs responsive to control signals received at the second and third control inputs.
