1. A method performed by a computer system for estimating a trial PPA metric for a logic component design evaluated at a trial design point, the method comprising: receiving the logic component design; receiving a reference PPA (power, performance, area) metric for the logic component design evaluated at a reference design point; accessing a PPA database that contains PPA metrics for multiple test components evaluated at multiple design points; determining, by the computer system, a scale factor for the logic component, the scale factor based on: scaling from (a) the reference design point to (b) the trial design point, of an equivalent test component to the logic component; and applying the scale factor to the reference PPA metric to determine the trial PPA metric at the trial design point, wherein the logic component design is providable for subsequent design and manufacturing of the logic component.
