Something is missing in this command

You don't set the "signal type" - you have to pass the function a waveform object. You can access the waveform object using (say):

v("/signalName" ?result 'tran)

or

i("/R1/PLUS" ?result 'tran)

and then pass this to the awvPlotSignals function.

Thanks Andrew!

It's much better now :)

And one additional question.

Which function I could use for set of  Context Results Database?

Regards,

Nikolay

Nikolay,

So do you mean the results database you get when you do v(...) without needing to pass ?resultDir ... within the v() call?

If so, you can use openResults() for this.

Andrew.

openResults() is what I needed. It's too easy when you know the right commands :D

Thanks.

Dear Andrew,

After 1 year... I'd be interested in representing the stability of my circuit in a polar chart.
I'm running a simple STB analysis but somehow I can't get the following working:

awvPlotSignals(getData("/loopGain" ?result "stb") ?graphType "polar")
"(\"foreach\" 0 t nil (\"*Error* foreach: second argument must be a list\" srrWave:0x288c70f0))"

Expecting a list, not taking a Waveform.
I've then checked the Help and tried to adapt the syntax from given

awvPlotSignals((("./ampsim.raw" (("ac-ac" ("net10"))))) ... )

to a 'wonky'

awvPlotSignals((("openResults()" (("stb" ("/loopGain"))))) ?graphType "polar")
"(\"eval\" 0 t nil (\"*Error* eval: not a function\" (\"openResults()\" ((\"stb\" (\"/loopGain\"))))))"

I don't get the syntax needed here...
Target would be to get a proper visual of Gain and Phase margins (which tend to be sometimes masked in the Bode representation) - getData("phaseMargin" ?result "stb_margin") and gainMargin are nice but I wouldn't trust them 100%...

Thanks in advance for your possible feedback,
Kind regards,

Matth,

awvPlotSignals is a pretty horrible interface. I'd use the simpler OCEAN interface:

newWindow()
displayMode("smith")
smithType("polar")
plot(getData("loopGain" ?result 'stb))

I would have expected: 

awvPlotSignals(list(list(openResults() list(list("stb" list("loopGain"))))) ?plotStyle "New Window" ?graphType "Polar")

to work, but I can't get it to behave. I get the graph, of Polar type, but there's no trace on it... whereas the 4 line approach above (which is much more readable) works fine. Note that you have to create a new window or sub window because you can't convert an existing rectangular graph into a smith or polar chart.

Regards,

Andrew.

Hello,

How should be expressed the argument for the signal which I would like to plot if it is in a hierarchy?

For example my signal is called signal_1 and it is in block called block_2.

If the signal is on top level the function probably should be something like this.

awvPlotSignals(list(list(openResults() list(list("tran-tran" list("signal_1"))))) ?plotStyle "New Window" ?graphType "Default")

But what about if it is in block_2

Regards,

Nikolay

OK, nevermind! I found the solution :)

Hi Nikolay,

You have to use the netlist name with “.” as the hierarchy separator when using this API (I think). You can see these names by using:

outputs(?result “tran-tran” ?map nil)

So for example (in my case openResults() didn’t have the “/psf” on the end - hence the strcat):

awvPlotSignals(list(list(strcat(openResults() "/psf") list(list("tran-tran" list("I7.net022"))))) ?plotStyle "New Window" ?graphType "Default”)

Personally I would just have used:

plot(v(“/I7/net022”) ?result ‘tran)

if this had come from ADE. If from a standalone netlist, the same as above, but with “I7.net022”. Essentially a leading slash means it is a schematic name which should be mapped using the info in the map/amap directory - if present. If not present in the netlist dir, you have to use the netlist hierarchy separators instead.

Regards,

Andrew.
