I have a problem with Cadence AWD. some times when i do a simulation for a while, AWD shows only a little of wave form. for example when i do a tran simulation for 100m sec, AWD shows only 20m sec of it. i have tried X axes range both in auto and manual range.
the problem remains until i reset icfb.
I'm not sure, but I had a similar experience with one of cadence' graphing tools a couple of years back, I think it was 20ms it wouldn't display past either, even though the sim ran successfully for much longer. The solution I found was to use another graphing tool, we have a few with our installation - I don't know whether they come as standard or whether they were add-ons our system admin guy installed.
Whether this will help in your case I don't know.
