A computer-readable storage medium that stores computer program code which, when executed by one or more processors, causes the one or more processors to execute tools for designing an integrated circuit (IC). The tools include a placing and routing tool that generates layout data and wire data corresponding to a net included in the IC by placing and routing standard cells defining the IC, the wire data including physical information of a wire implementing the net, and a timing analysis tool that calculates a wire delay with respect to the wire corresponding to the net, based on the physical information, updates the wire delay based on process variation of the wire, and calculates a timing slack by using the updated wire delay.

Computer-implemented method and computing system for designing integrated circuit by considering timing delay

A method includes performing, using a processor, a synthesis operation to generate a netlist from input data about an integrated circuit, placing and routing, using the one processor, standard cells defining the integrated circuit using the netlist, to generate layout data and wire data, extracting, using the processor, parasitic components from the layout data, and performing, using the processor, timing analysis of the integrated circuit according to timing constraints, based on the layout data and the wire data.

A computer-implemented method and a computing system for designing an integrated circuit are provided. The method includes generating wire data corresponding to a net included in an integrated circuit, the wire data including metal layer information of a wire corresponding to the net and physical information of the wire, performing timing analysis using the physical information of the wire included in the wire data to generate timing analysis data, and changing a layout of the integrated circuit according to the timing analysis data.
