US Patent:

7275230, Sep 25, 2007

Filed:

Jun 11, 2004

Appl. No.:

10/866457

Inventors:

Jason Todd Gentry - Wellington CO, US
Jack Douglas Benzel - Loveland CO, US

Assignee:

Avago Technologies General IP (Singapore) Pte. Ltd. - Singapore

International Classification:

G06F 17/50

US Classification:

716 13, 716 14, 716 15

Abstract:

The present invention is a method for collecting, analyzing, and displaying statistics regarding block pin placement prior to routing of an integrated circuit. The statistics are graphically displayed in a graphical user interface (GUI). The GUI graphically displays indications of where block pin congestion problems lie, which allows an integrated circuit designer to quickly pinpoint and correct pin placement in areas of pin congestion to alleviate congestion in these areas prior to routing.

Appl. No.:

8/961672

Inventors:

Jack D. Benzel - Loveland CO

Assignee:

Hewlett Packard Company - Palo Alto CA

International Classification:

G06F 1750
G06T 320

US Classification:

716 2

Abstract:

Enhanced capability design-rule halos for use in Computer Aided Design (CAD) software programs are described. Such enhanced halos, created around a design feature at the design rule distance from that feature, have the following characteristics: beveled corners for closer placement of adjacent non-parallel and/or non-perpendicular design features, level-to-level design rule halos, following a bend or turn in a design feature, the design rule halo automatically adapts to bends or turns in the design feature and associated changes in the design feature following the bend, following a bend or turn in a design feature, the design feature and the design rule halo automatically snap back, as required, to avoid a design rule violation with respect to an adjacent design feature, and the design-rule halo is prevented from extending closer to an adjacent design feature than the design rule distance. These actions are performed real-time and interactively.
