Hello Heystek, You will have to go through the timing reports and see which signal path is failing timing, and by how much.
Once you have an idea, you will need to sprinkle delay blocks and / or adjust latencies in your logic to get to a point where the place-and-route can find a layout that satisfies timing requirements. It's a bit of a black art, always hit and miss for me.
