Why is 'compile_preserve_subdesign_interfaces' changed to true?

(VO-12)Warning:

  • The value of variable 'compile_preserve_subdesign_interfaces' has been changed to true because '-no_boundary_optimization' is used. (OPT-133) You can also safely ignore these warnings.
    If you see errors or warnings related to unresolved module instances or unconnected nets, then you need to dig in and fix them.

    In semiconductor design, standard-cell methodology is a method of designing application-specific integrated circuits (ASICs) with mostly digital-logic features.
    Standard-cell methodology is an example of design abstraction, whereby a low-level very-large-scale integration (VLSI) layout is encapsulated into an abstract logic representation.
