Hi Greg,
	
	Gary Lau and I were discussing this today.  The values of Von and Voff
define a transition region for the switch.  This allows the program to
remain stable during the switch transitions.  It is rather strange the way
the model does this but they seem to know what they are doing.  I will
forward you and anyone else who is interested our off-list information on
this.  The instructions explain this but the PDF file does not convert to
pure text well.

BTW - I was wanting to post the MicroSim Demo but I don't have enough
server space :-(  I guess they have a demo CD they will send you.  This is
a good deal because it has all the help info included too.

	Terry
