Help on loading derived waveforms

Hi, all.

Maestro simulation that I am working with has ocean script added that calculates some values and generates waveforms and adds them to results as derived outputs.

They all get evaluated properly when I do "View Results".

Now i need to access these values and waveforms from skill code.

They are not contained in results database.

Is there a way to do it without opening results from History browser?

Thanks in advance.

Hi,

i am not sure what you want. The actual data ? Give us example.

i give you an example :

plot(getData("I61.MP8:ron" ?result "tran-tran"))
ocnPrint(getData("I61.MP8:region" ?result "tran-tran"))

You can recover the X and Y data from the curves with ocnPrint function.

I assume however that you want the value of ymax() or ymin()

wave=VDC("/I0/net019")

plot(wave) ;<= what does the "Evaluate button from your expression"

average(wave) = 0.5 ;<= for instance if net019 is a clock of [0 - 1V]

Sorry, my answer is not clear because your question is not clear.

Regards,

I have no ocean expressions after "View results" is done.

Derived expressions (both, waves and scalars) are not stored in results database, but calculated.

Something like you do with : wave = artListToWaveform(xyList)

I need to access waveforms and plot them.

You may be able to use calcVal("outputName" "testName") to retrieve the waveform object, which you can then plot (by passing to the plot() function)

Scalar results can also be retrieved with the axlReadHistoryResDB function - see the example at the bottom of this post.

Scalars are retrieved properly, but waveforms are still resolved to nil.

Please contact customer support - this is one of those "the devil is in the details" issues, and I certainly don't have the bandwidth for lots of back and forth trying to work out what exactly your setup is, and what you've tried - so I'd prefer to leave it to my colleagues who can follow this up directly.

No need for that.

Thank You for idea.

This:

wavefrm = calcVal(resName test ?cornerName cornerName ?historyName historyName)

did the job.
