No, I have not experienced this before. but you might want to make sure
that the device data structure is getting initialized correctly. When I
was trying to get the various bsimsoi models implemented, there was a
problem in defining the device structure and having the appropriate model
call the correct soi structure(pd vs dd vs fd). this may just be my
ineptness as a programmer.
Couple of things to look at:
1. are you sure that in implementing the level 49 model that it is being
called when running the spice deck.
2. In setting the up the device and the inp2m.c file are you sure that you
are accessing the level 49 model or is it seeing the default?
you may have to step into the device structure to make sure or put a debug
statement in the device structure to print out that it has been initialized
correctly.
Have you run any other spice decks? What was the outcome? Have you ran
this spice deck using the level 8 model, what happened?
let me know.
