*Warning* Wavenil is not a waveform object

Reinice

Hi All,

Good Day. I have an OCEAN script and I' am executing it in batch mode(ocean session). After the run finishes I' am having this warning:

*Warning* Wavenil is not a waveform object that can be displayed and will be DELETED automatically. name:"Signal_Name"

Here is the snippet of my script that I think is involve about the warning I' am getting:

newWindow()

awvPlotWaveform(awvGetCurrentWindow() list(value(value(v("/Signal_Name" ?result "tran") "temperature" -40) "modelFiles" "model.scs:top_ss") ?expr list("Signal_Name") ) )

YminNew = ymin(value(value(v("/Signal_Name" ?result "tran") "temperature" -40) "modelFiles" "model.scs:top_ss"))

YmaxNew = ymax(value(value(v("/Signal_Name" ?result "tran") "temperature" -40) "modelFiles" "model.scs:top_ss"))

STime = settlingTime(value(value(v("/Signal_Name" ?result "tran") "temperature" -40) "modelFiles" "model.scs:top_ss") YminNew nil YmaxNew nil 5 nil "time")

awvPlaceWindowLabel(awvGetCurrentWindow list(0 0.99) "settling Time" "STime")

ocnPrint(?output p5 "corner21,temperature=-40 AVDD=3.63 DVDD=1.2 Cload=2p modelFiles=model.scs:top_ss")

ocnPrint(?output p5 "Signal_Name,SetTime," STime)

addSubWindowTitle("Analysis:tran corner21,temperature=-40 AVDD=3.63 DVDD=1.2 Cload=2p modelFiles=model.scs:top_ss")

hardCopyOptions(?hcOutputFile "my_test_bench.png")

hardCopy()

1. Can anyone explain why I' am getting this warning?

2. Also in awvPlotWaveform, when I use ViVA to view the expression of my "Signal_Name" using a calculator, I' am getting only value(v("/Signal_Name" ?result "tran") "temperature" -40) instead of value(value(v("/Signal_Name" ?result "tran") "temperature" -40) "modelFiles" "model.scs:top_ss") as written in the script above. I don't know why is this occurring.?

3. Is there a work around where I can get the correct expression of my "Signal_Name"?

Actually this post is related to my previous post (How can I acquire waveform expression using a trace in ViVA?  started by Reinice  on 12 Nov 2012 06:46 PM)

btw, I' am using version IC06.15.132-615. 

Thank you very much in advance.

Best Regards,

  • Presumably the value(value(v("/Signal_Name" ... is failing and returning nil. That's presumably because it doesn't contain the "family" data for one of the sweeps. The fact that when you plot the signal in ViVA it generates an expression without the outer value() statement might suggest that this info isn't there.

    It's really hard to answer this without seeing your data, because it's difficult to know what (if anything) you're doing wrong.

    Could you submit this as a service request (with enough data to show the problem)?

    Best Regards,

    Andrew.
