Hi, Heystek, I think the build will generate a timing report in a file that ends with ".twr". If it's not, you can generate one using the "trce" utility (part of ISE). This will tell you how many nets failed timing and show details of the N worst offenders (I think N defaults to 3 or maybe 10?). If you have a large number of nets failing timing it's likely more difficult to rectify, but if there's only a few it's usually not too hard to resolve.
