Period of functional simulation period too short

Although I'm very new to Quartus, I'm starting to realize it's true power compared to other piece of softwares that were extremely limited in their simulation time range. I've always had to brake my circuits into blocks in order to check the functionality of each section. I'm aware of the problem that you're mentioning when time range are stretched.

I've simulated the full circuit with Quartus in one shot of 800x528 ns simulation time range with no problems at all. Being new to Quartus, I'm aware that there's a lot functions to discover that were simply not used in the other pieces of softwares I've been using until now.

Again, thanks a lot for your time and your precious help.
