1. A computer-implemented method for generating performance targets for related semiconductor devices, during development of a new technology node, said method comprising: accessing, by a computer, initial sets of performance targets, each initial set being associated with a corresponding one of said related semiconductor devices, comprising multiple performance targets associated with multiple values of multiple parameters and being generated based on at least one of prior technology node hardware measurements, new technology node prototype hardware measurements and new technology node numerical simulations; plotting, by said computer in a first graph, multiple first curves such that each first curve is associated with a different one of said related semiconductor devices and represents values of a specific performance target as a function of values of a specific parameter for a corresponding one of said related semiconductor devices; and analyzing, by one of said computer and a user, said first graph to identify inconsistencies that are indicative of inaccurate performance targets in said initial sets and to adjust said performance targets to resolve said inconsistencies and eliminate said inaccurate performance targets before using said initial sets in a modeling stage in said development of said new technology node.
