摘要： A method and system for performing dummy metal insertion in design data for an integrated circuit is disclosed, wherein the design data includes dummy metal objects inserted by a dummy fill tool. After a portion of the design data is changed, a check is performed to determine whether any dummy metal objects intersect with any other objects in the design data. If so, the intersecting dummy metal objects are deleted from the design data, thereby avoiding having to rerun the dummy fill tool.

摘要： A tool and method for implementing engineering change orders. The tool and method provides that a change file is checked, equivalent engineering change orders are computed and applied to an active cell. The engineering change orders are registered with a pre-determined tool name, and it is detected and reported if another tool needs to be run to restore routing information. The active cell is not automatically saved after the engineering change orders are applied. Instead, a user must manually save the active cell after the tool is run. The tool can work with three different name spaces: Verilog, VHDL and Avant! Verilog.
