Accessing results of an alter statement with SKILL

ChrisEAS

Hiya!

I'm having trouble accessing the results from Spectre's alter statement. I can't figure out what's wrong with my code. I've included a stimulus file containing the following statements:

alter1 alter mod=mymodel param=vth0 value=-0.7
dc1 dc dev=V8 param=dc start=-2 stop=0 write="spectre.dc" oppoint=rawfile \
    homotopy=all maxiters=150 maxsteps=10000 annotate=status

alter2 alter mod=mymodel param=vth0 value=-0.6
dc2 dc dev=V8 param=dc start=-2 stop=0 write="spectre.dc" oppoint=rawfile \
    homotopy=all maxiters=150 maxsteps=10000 annotate=status

After the simulation finished successfully, I was trying to access the results as follows:

 selectResults("dc1-dc")
res1=IS("/M1/S")

 selectResults("dc2-dc")
res2=IS("/M1/S")

Selecting the results seems okay. However, res1 and res2 keep being completely identical. So far I've figured out that the second alter statement appears not to be saved correctly. The result returned are always results from the first alter statement.

I'd really appreciate some help here. Thanks.

    Okay, I just made some headway with my problem. By using

    getData("/M1/S")

    I can finally access the two waveforms. However, I wanted to evaluate some output expressions which contain "IS(..)" instead of "getData(..)". Is there really no way of using "IS(..)" when working with multiple analyses?
