boundary optimization synthesis

Boundary optimization results fastest critical paths and smallest design.

Basically four optimizations collectively called as Boundary optimization in synthesis (wrto DC).
a) Inversion pushing across hierarchy.
b)propagation of equal and opposite information
c)propagation of unconnected /undriven ports.
d) propagation of constants..

I am not sure about multilvel Boundary optimization...

Regards,
Sam
