How to mimic a click or selection on a waveform in ViVA

fatcat1206

Hi All

Currently, I am facing a bug for the "Spec Marker": "Spec Marker" will not be displayed by default when running corner simulation, even with the "visibiltyMode" of "Spec Marker" is set to be "on".

With Cadence Support, a CCR has been filed already. But before waiting for the results, I'd like to develop some work around to fit our urgent needs.

What I notice is that:

After clicking the waveform in the ViVA, even in a blank place, the ViVA window seems to be triggered, and then the "Spec Marker" is displayed and stay there afterwards.

I try to mimic this action, and loop through all the sub-windows, then I can display all the "Spec Marker".

I tried some API from "awv*" families, unfortunately none of them succeed.

Does anyone have a clue for it?

Thanks in advance.

Best Regards

Yi

  • Hi Yi,

    Looking at this with the AE who's working on your case, it seems that it works in some cases (for example the data I tried it with, and some of her cases) but not others. We haven't figured out yet what the criteria are when it works and when it doesn't.

    In the meantime I found that I can write some code which iterates over all the windows and sub windows, and selects the curves in turn in each window. From trying this in a broken release (IC616 ISR11) where I do see the problem, it does seem to solve the issue for me. It's using the function for the bindkey which selects all traces in a sub window, so whilst that's private, it's pretty safe, especially as this is a workaround anyway rather than a long-term solution until we can fix the real issue. That code is below:

Function to iterate through all ViVA windows and 
subwindows, and select curves in turn. This is to workaround
an issue where spec markers are not always displayed, even
if they are turned on and you have:

envSetVal( "viva.specMarker" "visibilityMode" 'string "On" )

This was broken in IC616 ISR11, and supposed to be
fixed in IC616 ISR13. However, in some cases it remains; CCR
1639141 has been filed for the remaining issue.

This does use one private function, but given that it's
the function used for the shift-ctrl-A bindkey in ViVA,
it's pretty safe.
