13 years agoI was playing with the waveform editor in Modelsim 10.0c (Quartus 11.1sp1) last week. I don't recall the exact procedure, I just followed the documentation - from the Modelsim GUI click on Help -> PDF Documentation, User's Manual.
Since you are just starting to use Modelsim, let me give you some advice - you are going about it the wrong way. Drawing a waveform and using that as the basis for your simulation stimulus works ok for some very basic tests. However, as you gain more experience with the tool, you will find that what you really need to create is a model of the device you are interfacing. I've posted some very simple examples in these threads: http://www.alteraforum.com/forum/showthread.php?t=32386 http://www.alteraforum.com/forum/showthread.php?t=38988 http://www.alteraforum.com/forum/showthread.php?t=35572 http://www.alteraforum.com/forum/showthread.php?t=34391 and a more complicated example in this Wiki page http://www.alterawiki.com/wiki/using_the_usb-blaster_as_an_sopc/qsys_avalon-mm_master_tutorial Run some of these tests, and you'll see how the simulation-only stimulus 'creates' waveforms that interact with the synthesizeable logic.
