SignalTap in particular looks promising.

Here's a quick getting started guide for you.
1) Bring up the SignalTap GUI.
2) Click on the setup tab (you'll see it near the bottom left, its probably selected by default).
3) Double click in the blank area. This will bring up the Node Finder GUI.
4) On the 'Filter:' menu, select 'SignalTap II: pre-synthesis'. Then click on the list button.
5) Double click on signals in the list on the left side of the GUI to add them to your signaltap signal list (they appear on the right). When you're done, click ok.
6) Select a sampling clock. On the right side of the GUI click on the button next to the clock source. It brings up the Node Finder GUI again. Select pre-synthesis again, and then select a clock source, eg., clkin_50MHz (or whatever your external clock is called).
7) Select a sample capture depth, eg., 2k (its on the right, under the clock selection)
8) Save the SignalTap setup (click yes when it asks you if it should add the setup to the current design), and resynthesize your design.
9) Download the new design and SignalTap should detect it (if not, on the right hand side of the Signaltap GUI, select the USB-Blaster and scan for the design).
Have fun!
