I have Quartus II 13.0.1 web edition? When I try to simulate using University Program WMF the end time is limited to 100us. How can extend it? I saw in tutorials that it is not limited.

Yes, I know this. First, the time units are only ns and us. It is a dropdown menu, When I try to put more than 100us, it says "Invalid entry. Please enter a value between 10ns and 100us."
