Load bearing insulation and method of manufacture and use

A building material which comprises cement, cellulose fibers and admixtures is used in the fabrication of bricks, panels or other building products. The manufacture of this building material is accomplished by adding water, paper, a water repellant composed of calcium stearate, and a sodium silicate to act as a fire retardant material. The mixture is then thickened with cement and a second batch of concrete admixtures including a superplasticizer composed of a polyester polyacrylic polyol and an air entraining resin or surfactant to create an air entrained, viscous material for inserting in a mold or extruding through a press to form load bearing and insulating building materials. The resulting product can be formed into blocks or panels and the panels can be coated with polyurethane / polyurea coating to be bullet and blast resistant.

Method for eliminating negative slack in a netlist via transformation and slack categorization

A method for eliminating negative slack in a netlist representing a chip design uses a contrived timing environment to overlay information onto the design environment during logic and physical synthesis phase. The overlaid timing information determines which netlist transformation provides a maximum leverage for the negative slack elimination and a way for creating a dynamic transformation recipe tuned for each design. The method further provides upper bounds on the negative slack elimination to prevent the netlist transforms from being applied to situations exceeding the capabilities for improving the design.
