Implementing Useful Clock Skew Using Skew Groups

Clock skew (sometimes called timing skew) is a phenomenon in synchronous digital circuit systems (such as computer systems) in which the same sourced clock signal arrives at different components at different times due to gate or, in more advanced semiconductor technology, wire signal propagation delay. The instantaneous difference between the readings of any two clocks is called their skew. WebFeb 6, 2024 · Clock Groups : set_clock_groups Asynchronous Clocks.

"WebIn general, not all-skew parameters are of interest, but their discussion is included for illustration. The goal is to minimize skew to an acceptable value. The rule of thumb is that clock skew should be < one-tenth of the system clock period. For example, a system operating at 100 MHz has a period of 10 ns, and the clock skew should be <1 ns.
