What controls "Value" vs Plotting on waveform window.

analogy

This is about ADE smulations.When using cross function in calculator, values are plotted on waveform window instead of being shown in value field.Wondering what might be the reason ?

Thanks.

P.S. Sorry for image.Somebody really needs to fix media manager on forums.

  • OK. You have used the infotimes parameter of the tran analysis to list a single time where you want to compute the operating point, and also turned off the final operating point checkbox on the tran options form.

    Because you can specify multiple times in infotimes it will plot operating point parameters with OPT versus the time at which they were captured. If there's only a single time, there's no lines to be drawn between points, but there's still an x-axis of time.

    Clearly if you only have a single point, the cross() function isn't going to work - because nothing crosses. So as you can see, ADE is reporting the cross() expressions as blank - because it got no result.

    So, you either need to add more time points in the infotimes parameter, or maybe better you could use the Outputs->To be Saved->Select OP parameters that was introduced in IC616 ISR10 (IC6.1.6.500.10) and then you can use the OT button that was introduced in IC616 ISR12 (IC6.1.6.500.12) to plot it (otherwise you'd have to use the results browser). With this you get the operating point information at every timepoint and then cross() will make sense on this.

    Alternatively, if your objective is just to display the operating point info at the single timepoint rather than finding the crossing point of anything, use value(OPT(...) 6.5p) or whatever the time you want to measure it at is.
