How to check clock skew - Xilinx

WebIf the input ports are synchronous to external clock, the paths can be constrained for setup as, input_delay + comb_delay (max) < clock delay path (clock skew) + T (clock period of clock) – setup time of latch FF . And For the hold constraints as . input_delay + comb_delay (min) > hold time of latch FF + clock delay path (clock skew). 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. proprietary item

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. At 500 MHz, the period is reduced to 2 ns and clock skew should be <20 ps. proprietary issues in business planWebApr 22, 2015 · i changed below settings in Time Zone and post changes i am getting getting Clock skew detected alerts in logs.
