if it is inserting a "black box", full layout completed in GDS-II /
Alliance AP,
as a "unit", with the entire contents of that "black box" 100% full
completed
and laid out already, then this should not be a problem at all.

if however that "black box" is *missing* the internals of the FlexLib cells
and it is expected that coriolis2 should substitute the contents of named
FlexLib cells *INTO* the PLL block, then that becomes an issue.

which one is it?
