Abstract
Various techniques related to clocking signals used for automated circuit design and simulations are disclosed. In some embodiments, a method includes receiving first and second asynchronous clock signals having a first phase relationship at a first time, and sampling the second clock signal at transitions of the first clock. The method further includes storing the samples; and analyzing the samples to ascertain the first phase relationship of the second clock signal with respect to the first clock signal and provide a representation of the first phase relationship. Other embodiments are described.
