Techniques for determining the quality of a clock signal are provided. In one example, a method can comprise comparing, by a sensory circuitry of a system, a first output of a first sensor and a second output of a second sensor. The first output and the second output can be based on a parameter of a clock signal. Further, in some embodiments, the first sensor and the second sensor can be local clock buffers. The method can also comprise determining, by a controller of the system, a quality of the clock signal based on the comparing of the first output and the second output.
