Parasitic annotation and simulation using the sbaLib devices

Hi all,

I'm trying to balance out some parasitic caps, but wanting to iteratively simulate the effects of adding and substratcing caps.

 I've placed sbaLib symbols in my schematic and the built an av_analog_extratced view based on those selected nets.  I undertsand you can avoid this by using the 'selected nets proper' option in the Assura RCX dialog box.

 However, my motivation for the painful way, is to be able to quickly switch on and off, parasitics without having to RCX the layout again and again. 

sbaLib caps have parameters for capacitance and initial values.  I can't find a manual on these devices, nor are they discussed on Google.  When backannotating, I placed these symbols on my schematic view and then refined the analog view to build the av_analog_extratced view.  However, when I switch the view back to schematic in my Hierarhy editor, I don't see an entry for any instance from the sbaLib, regardless of whether 'sbaLib is listed in the Global bindings Library list.  The netlist doesn't show it either.

 So what's the point of the capacitance parameter you can override in the 'query' form of the spcapacitor element?

If I want to quickly add capacitors to a net in the schematic, which has an assoicated extracted view, is there any way to link the 2 databases together (caps from the av_analog_extratced, and the addtional caps added in the schematic view).  OR override the extracted capacitance with a larger/smaller capacitance?

 Only other option that springs to mind is to have a separate version of my schematic, upon which I manually added all the parasitic caps as 'analogLib' elements, and then add more.  But that's a pain!
