Filed:

Dec 7, 2004

Appl. No.:

10/904950

Inventors:

Michelle K. Cook - Georgetown TX, US
Bruce R. Archambeault - Four Oaks NC, US
Charles R. Gates - Poughkeepsie NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/50

US Classification:

716 5, 703 13

Abstract:

An improved solution for designing and/or evaluating a circuit is provided. A rule violation can be detected in design data for the circuit and a prediction can be generated based on an adjustment to the design data. For example, multiple predictions can be generated based on an adjustment window for an adjustable parameter in the design data. The predictions can be displayed to a user, who can determine a desired modification to the design data. The modification can be implemented by the user and/or automatically implemented by a circuit design tool.

Abstract:

Disclosed is a polyethylene composition. The composition comprises single-site multimodal resin A and single-site multimodal resin B, wherein resin A differs from resin B in molecular weight, in monomeric composition, in density, in long chain branch concentration or distribution, or in combinations thereof. Disclosed is also a method for making the polyethylene composition. The method comprises polymerizing, in the presence of two or more single-site catalysts, ethylene or its mixture with a C-Cα-olefin to form a first multimodal resin and continuing the polymerization in the presence of the same catalysts but in a different hydrogen concentration, in a different monomer composition, or at a different temperature to form a second multimodal resin.
