Methods of independently migrating a hierarchical design are disclosed. A method for migrating a macro in an integrated circuit comprises: determining an interface strategy between a base cell in the macro and the macro, the base cell including an interface element involved in the interface strategy; migrating the base cell independently with respect to the macro based on the interface strategy; initially scaling the macro; swapping the migrated base cell into the macro; and legalizing content of the initially scaled macro.
A method for migrating a macro in an integrated circuit, the method comprising:
A method of determining a relative position between an updated version of a macro level shape and an updated version of a cell level shape, the macro level shape and the cell level shape abutting one another in an original integrated circuit layout, the method comprising:
