What is Clock Skew?

Given two sequentially-adjacent registers, Ri and Rj, and an equipotential clock distribution network, the clock skew between these two registers is defined as




Tskew-i,j = Tci - Tcj



where Tci and Tcj are the clock delays from the clock source to the registers Ri and Rj, respectively.
