TRANSPARENT EDITING OF PHYSICAL DATA IN HIERARCHICAL INTEGRATED CIRCUIT DESIGN

摘要

Systems and techniques are described for transparently editing physical data in hierarchical IC designs. Some embodiments allow a user to access objects at any level of the physical hierarchy and to specify a particular editing operation (move, rotate, delete, cut, split, etc.) relative to the top-level block. The embodiments can automatically transform and apply the editing operations in the context of the block where the edited object resides. Systems and techniques for automatic context selection, logical connection analysis, cross hierarchical routing, transparent hierarchical routing, and maintaining physical connectivity across hierarchy boundaries are also described.

主权项

1. A non-transitory computer-readable storage medium storing instructions for a circuit design tool that, when executed by a computer, cause the computer to perform a method for editing objects in a circuit design, the method comprising:
creating a second object based on a first object in the circuit design, wherein said creating comprises applying a sequence of one or more geometric transformations to the first object; applying one or more edits to the second object, thereby obtaining an edited second object; applying the sequence of one or more geometric transformations in reverse order to the edited second object, thereby obtaining an edited first object; and saving the edited first object in the circuit design.
