Vivado netlist simulations do not come out of reset till 100 ns. The reason for this is there is a global set/ reset ( GSR ) in Xilinx FPGAs which retains the initial values on all the fl ops for the fi rst 100 ns of simulation time.
If you are planning to reuse your testbench from the RTL, ensure that in your testbench, the reset is at least asserted for 100 ns before pumping in the actual vectors.
Memories are one area which might expose a difference in RTL vs. synthesized netlist. In cases where the RTL description is mapped to a simple dual port or true dual port block RAM, during address collision , there would be mismatch. Look for warnings during netlist simulation.
In addition, other conventional cases of synthesis vs. simulation mismatches apply.
