Vivado HLS - Small Target II results in larger II


After a smaller II directive is specified, Vivado HLS results in a larger II.


If the tool cannot achieve user requested II, it will try a larger value until it can implement the design. However, in this case, HLS synthesis results in a higher II implementation than previous implementation after an updated lowered II is requested. This issue will be resolved in future tool release.
