Switching between DC Operating Points & Component Parameters

[Gerd]

Hi,

When i annotate DC Operating Points after a simulation, it seems i
can't go back to annotating the original Component Parameters. This
warning pops up for every instance label:

*WARNING* artFindPropByName: Unable to locate property for inst="M0"
property-name="paramEvaluate"

I'm doing this exercise with a single nMOS transistor for which some of
my BASE CDF parameters in the "Interpreted Labels Information" section
look like this:

* paramDisplayMode = parameter
* paramEvaluate = literal
* paramSimType = DC

After running a DC analysis and clicking: Results->Annotate->DC
Operating Points, the correct DC operating point values appear, but
when i check again the BASE CDF for the nMOS component, the above
settings have changed to:

* paramDisplayMode = parameter
* paramEvaluate = not set
* paramSimType = not set

EFFECTIVE CDF has:

* paramDisplayMode = opPoint
* paramEvaluate = not set
* paramSimType = DC

Going back to Results->Annotate->Component Parameters results in the
warning message above. I guess the baseline is: how can 'paramEvaluate'
change from 'literal' to 'not set' in the BASE CDF ?
Or is there something else going on?


Thanks,
Gerd
