spectre sweep statement in Ocean

Create a file sweepAnalysis.scs containing this:

//
sweepCAP sweep param=CAP start=0.8p stop=2p step=0.2p {
  ac ac start=100 stop=150M dec=20
  }
dcOp dc write="spectre.dc" maxiters=150 maxsteps=10000 annotate=status
dcOp2 dc write="spectre2.dc" maxiters=500 maxsteps=10000 annotate=status

(note I'm also answering your other post at the same time ;-> )

Then in your OCEAN script:

 simulator( 'spectre )
design("mylib" "ampTest" "schematic")
resultsDir( "./simulation/ampTest/spectre/schematic" )
path( "./Models" "." )  ; In my case I put sweepAnalysis.scs in the working dir, hence adding "." to the path
modelFile(
    '("myModels.scs" "")
    '("sweepAnalysis.scs" "")
)
desVar(      "CAP" .8p    )
temp( 27 )
run()
selectResult('ac)
plot(v("/out"))

You could of course put a full path in the modelFile statement.

Alternatively, rather than referencing sweepAnalysis from the modelFile function, you could use:

stimulusFile("./sweepAnalysis.scs" ?xlate nil)

You'll need the run() in both cases - all these are both doing are adding include statements into the input.scs.

Note that I did two DC analyses in the file (as per your other example). You can access these results:

results() =>  (subckts instance dcOp model variables
    output designParamVals "dcOp2-dc" ac primitives
)

Notice that one of them has been "aliased". You can also get the unaliased names:

 results(?noAlias t)
("subckts-info.subckts" "element-info" "dcOp-dc" "modelParameter-info" "variables"
    "outputParameter-info" "designParamVals-info" "dcOp2-dc" "sweepCAP_ac-sweep" "primitives-info.primitives"
)

So you can do: selectResult('dcOp) or selectResult("dcOp-dc") or selectResult("dcOp2-dc") to access the two DC analyses.

Hope that helps!

Kind Regards,

Andrew.
