Component editor in SOPC

SOPC Builder 7.2 is really an interim product. The component editor and its accompanying documentation is poor at best. Supposedly 8.0 will be much more complete. However, what you need to do is add another clock interface.

1 - Add a new signal to your list of signals.

2 - In the interface column change the interface to "new Clock Input". Then change the signal type to "clk".

Now on your interfaces tab you'll see your new clock input. You can also change the name of it if you would like.
