WebApr 18, 2014 · Now the design misses timing on the max_skew specification. Looking at the worst case path, I see that the fitter has added 13.658ns (!) of routing delay between these 2 flops (which are in the same LAB), presumably in order to meet the hold time requirement between these flops. WebI know this is a kind of asynchronous scenario and the traditional method is the use of 2 FFs or an asynchronous FIFO to synchronize the data. However, since these two clocks have a fixed phase difference, ... Use SDC format for timing constraints on Xilinx CPLDs. 3.
