Your design has not made timing. You can generate your bitstream if you disable the "Treat timing closure failure as error" option (you can do this by modifying the edk project file, system.xmp). This is REALLY, REALLY NOT recommended. Your design will, in all likelihood, not work as expected at the desired clock frequency. What you need to do is look at your timing report and identify the blocks in your simulink design which are causing problems. (you will find the timing report in XPS_ROACH_base/implementation/system.twr) It is somewhat of a dark art interpreting the .twr file, which I wont cover here. Once you have identified the problem block you need to adjusting the latency for the primitives that are causing the timing problem. Good luck.
