WebNov 6, 2015 · i have read that clk gating (in any way) removes the clk from the dedicated clk route and puts it into the logic fabric thereby adding skew into the design. does that hold true for arria10 FPGAs too? and is this skew always considered bad? and if yes, within what range, is the skew because of clk-gating acceptable? help :) z.
