Plot transient OP vs. Time

Hi,

I want to plot the transient operating point of a device versus time (e.g device Msrowin, operating point for ids).

One way to achieve this is to create a file "tran_op.scs" and include it with the model files. The file content will be:

             save Mswroin:ids

In the output definitions I would add:  getData("Mswroin:ids" ?result 'tran), then I can plot the "ids" versus time.

Questions:

1) How should the file syntax look like, when the device is in a subcircuit (e.g "/DUT/Mswroin" does not work) ?

2) Is there another (easier) way to evaluate the transient operating point vs. time ?
