A system for generating an Open Library Architecture Delay and Power Calculation Module. The system includes a user interface for generating and submitting requests that specify configurations and types of memories for which Open Library Architecture Delay and Power Calculation Modules are needed. A server is configured to received the requests and produce Open Library Architecture Delay and Power Calculation Modules in response thereto.

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.

A method and computer program product for early physical design validation and identification of texted metal short circuits in an integrated circuit design includes steps of: (a) receiving as input a representation of an integrated circuit design; (b) receiving as input a physical design rule deck that specifies rule checks to be performed on the integrated circuit design; (c) generating a specific rule deck from the physical design rule deck wherein the specific rule deck includes only physical design rules that are specific to one of identifying texted metal short circuits in the integrated circuit design and power distribution and input/output cell placement in the integrated circuit design; and (d) performing a physical design validation on the integrated circuit design from the specific rule deck.

A method of implementing an engineering change order includes steps of: (a) receiving as input an integrated circuit design; (b) receiving as input an engineering change order to the integrated circuit design; (c) creating at least one window in the integrated circuit design that encloses a change to the integrated circuit design introduced by the engineering change order wherein the window is bounded by coordinates that define an area that is less than an entire area of the integrated circuit design; (d) performing a routing of the integrated circuit design that excludes routing of any net that is not enclosed by the window; (e) replacing an area in a copy of the integrated circuit design that is bounded by the coordinates of the window with results of the incremental routing to generate a revised integrated circuit design; and (f) generating as output the revised integrated circuit design.

A method, a computer program product, and an apparatus for performing a trimmed verification analysis comprising selecting layers of interest for a trimmed analysis, eliminating layer definitions for unselected layers to create a trimmed rundeck, and performing a layout versus schematic verification comparison to generate a trimmed error report for the selected layers of interest.
摘要:
A method of partitioning an integrated circuit design for physical design verification includes steps of receiving as input a representation of an integrated circuit design having a number of physical design layers and a composite run deck specifying rule checks to be performed on the integrated circuit design. The composite run deck is partitioned into partitioned run decks so that the number of physical design layers referenced by each of the partitioned run decks is a minimum. The representation of the integrated circuit design is parsed to filter only the physical design layers required for each of the partitioned run decks into a filtered data deck for each of the partitioned run decks. The filtered data deck is generated as output for each of the partitioned run decks.
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.

摘要:
A method of debugging an IKOS model. The method includes mapping information contained in either a .pin or .lde file or both into corresponding files which are more user-friendly, readable and editable. Preferably, a .v file which is readable to create a schematic view of the cell is also created and the schematic view can be viewed and analyzed. Then, the one or more user-friendly files which have been created can be read and edited, and the .pin and/or the .lde file is re-created. Then, a tool is used to analyze the .pin and .lde files again and determine whether there is a functional or timing failure.

A method of waiving verification failures is disclosed. The method generally includes the steps of (A) generating a plurality of circuit error files by performing a plurality of physical verifications on a plurality of circuit designs, the circuit error files containing a plurality of circuit errors of the circuit designs, (B) generating a system error file by performing an additional physical verification on a system design, the system error file containing a plurality of system errors of the system design, the system design incorporating the circuit designs and (C) generating a valid error file by removing the circuit errors from the system error file, the valid error file containing a plurality of valid errors comprising a subset of the system errors.
