Memory issue and the crash while plotting in wavescan

RFStuff

Dear All,

I ran a AMS simulation of 500us. I then tried to plot various waveforms in WaveScan.

First, it took around 5 minutes to plot the first wave. When I tried to plot next 3 waveforms, I see the following warnings and then Virtuoso crashes.

May, I know why this warnning is coming up and how to fix it.

  • OK, you don't really mean Wavescan (it's not been called that since 2006) and are using ViVA, but it appears that something is causing an excessive (at least I assume it's excessive) use of memory. I'm not aware of why that might be unless you've got huge waveforms with lots of points. The graphs you've plotted there appear to be logic, so I can't imagine they are consuming that much memory.

    I think you'll have to contact customer support for this. There are a lot of variables - which output format is being used, which IC subversion is used, how big the result data is, and so on - but interrogating that will really need to be done via support.

    Andrew.

    Thanks Andrew.

    Yes, with logic waveforms it should not take much memory. I need to contact customer support.
