The \Alliance flow is based on the \MBK data-base, which has one data-structure
for each view. That is, \LOFIG for the \logical view and \PHFIG for the \physical
view. The place and route tools where responsibles for maintaining (or not) the
view. The place and route tools were responsible for maintaining (or not) the
coherency between views. Reflecting this weak coupling between views, each one
was stored in a separate file with a specific format. The \logical view is stored
in a \vst file in \VHDL format and the \physical in an \ap file in an ad-hoc format.
