Webb2 aug. 2011 · If you got 88000ns positive slack with 111ns cycle time, it must have a huge clock skew, pushing the capturing clock edge way ahead, and natually it's likely to have a hold violation. THe clock skew remains the same regardless of the cycle time, and capturing edge is always at the same location in time. Webb23 juni 2010 · 1,286. Activity points. 1,813. In my opinion, if you are working on a chip (flat design), the global skew is not important if you can close timing, especially for hold. Buf if you are working on a block and it is a full chip clock domain, the global skew will make effect at full chip timing for global clock balance. motorcycle tires speed rating chart

WebbIn simplest words, Clock Skew is the time difference between arrival of the same edge of a clock signal at the Clock pin of the capture flop and launch flop. Any signal takes some time to travel from one point to another. The time taken by Clock signal to reach from clock source to the clock pin of a particular flip flop is called as Clock latency. WebbWhen clock skew is intentionally add to meet the timing then we called it useful skew. In this fig the path from FF1 to FF2 Arrival time = 2ns + 1ns + 9ns = 12ns Required time = 10 ns (clock period) + 2ns - 1ns = 11ns Setup slack = required time – arrival time = 11ns -12ns = -1ns (setup violated) In this fig the path from FF2 to FF3 motorcycle tires wichita ksWebbClock 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. motorcycle tires white wall
