[[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 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]] Workshop > Parts Menu > [[Transmission Lines]] > ...
