Simulation Grid Size

Hi,

 

I am currently using Quartus Prime Version 20.1 Lite Edition on a Surface Pro 7.  The issue is that the simulation grid size will not adjust to anything lower than 20 ns.  I can go to Edit -> Grid Size and set it to anything greater than or equal to 20 ns, but if I set it to anything less than 20 ns, for example 5 ns, then the parameter changes but the grid size, on the simulation window, defaults to 20 ns.  Please help.

So maybe the display doesn't show smaller grid size until you zoom in or make the window bigger.  I use ModelSim or QuestaSim.  It's been a long time since I used .vwf.

Can't you just zoom in with the magnifying glass?

Yes I can, but is there anything I can do to get the grid size of 5 ns to show up on the simulation window?  The lab I am working on requires me to submit screenshots of the simulation window showing that I selected the correct grid size for an End Time of 1 us.

What's different between the 2 waveforms you've posted?  The grid is 20 in the first one and 10 in the second, so you did something to get the grid smaller than 20.

All I did was maximize the simulation window.
