Period of functional simulation period too short

[Altera_Forum]

Hi, 

 I've problems getting Quartus 6.1 displaying longer periods of functional simulation. By default, I'm reading on the master timing bar a simulation period ranging from 0 ps to 1us. My design requires longer periods of simulations. Although I'm following the help procedure by going to the "Assigment" tab -> "Setting" and checking the "end simulation at" checkbox and write down the needed simulation period, the master time bar keep showing 1us as the longest simulation period. For example, what if I want to simulate for 100 us?  I've tried to decrease the clock period for the same max 1us simulation time range. It does work but compilation time uncreases dramatically. Finally, what was left is to simulate one block at a time using the same clock for all the blocks that make up the whole circuit. Actually, I would need a simulation of 800x528 ns to simulate a VGA controller.   Am I not following the right procedure to get longer simulation times?   Thanks for your help.

Did you make your simulation stimulus longer than 1 us? If using a .vwf file, go to "Edit --> End Time" while the waveform window is open.

Thanks Brad, 

 That simple? - Will do.  Thanks a lot.

Don't forgot to check the inputs for the time added at the end of the file. The waveforms might just get extended, but that might not be what you want.

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.
