WebTo get the most effective results from the Designer software, you need to set the timing constraints close to your design goals. Sometimes slightly tightening the timing constraint helps the optimization process to meet ... - Set the location of Core, RAM, and FIFO macros - Create Regions for I/O and Core macros as well as modify those regions ... WebMay 3, 2024 · Write clock has a phase shift of 90 degrees which corresponds to 2.5 ns. The time difference between your two clocks is 5 ns. It is 200 MHz. So depending on the clock frequency and shift, the …

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.
