New analogue and digital device models from TI contain
...
the token GND in their subcircuit. Up to now ngspice has
declared GND as global and replaced it by 0.
Now, if PS is selected as compat mode, GND is not
declared as global, and is not replaced inside of a subcircuit.

Moving window filtering with function 'newvec = mtimeavg(vec)'
...
Window of fixed time width given by 'set mtimeavgwindow=400u'
Length and scale of newvec resembles the original vetor vec.
Large vec and large mtimeavgwindow take their time.
OpenMP is used if available.
