I haven't used Calibre as extraction tool for a long time,
but in the PEX GUI there is under 'Outputs' the
option 'Extract Type' which let you
define RCC == Distributed RC + coupling caps
Which must be the command line option
calibre -xrc -rcc

Oops I realized that my suggestions is for Calibre xRC
not xCalibre, for what you initially were asking.

I don't know if you can extract coupled Cs with xCalibre,
may be you have to upgrade.

I think it's only possible to have a distribute RC extraction or
a lumped C only extraction with Calibre, where lumped always is
decoupled.

But as I said it's a while since I worked with Calibre for
extraction.

If someone might know it better and I'm wrong please correct me.
