Abstract:
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.
