== RF.Spice A/D vs. B2.Spice A/D ==
[[RF.Spice A/D]] is an extensive superset of [[B2.Spice A/D]], offering additional RF simulation capability plus a comprehensive library of system-level black-box virtual blocks. Due to popular demand, EMAG Technologies Inc. continues to offer [[B2.Spice A/D]] simply as the '''"Lite Version"''' of the [[RF.Spice A/D]] product. The [[User Interface|user interface]] of the two products are now identical and both share the same consolidated online documentation and tutorial lessons. However, the users of the [[B2.Spice A/D]] edition will find the following submenus or menu items greyed out and inaccessible:
* [[RF.Spice A/D]] Workshop > Parts Menu > [[Multiport Networks]] > ...
* [[RF.Spice A/D]] Device Manager > File Menu > Create New Generic T-Line Component from S-Parameter Text File > ...
Needless to say, the parts database of the [[B2.Spice A/D]] edition is a reduced subset of the parts database of [[RF.Spice A/D]].
