Claim:
1. A method, comprising: establishing a product template created from product disposition measurements made on a product in a first manufacturing line and which qualifies products manufactured in one or more different manufacturing lines; producing products on the one or more different manufacturing lines, the products including product macros placed on a chip; establishing allowed parametric match from line to line which includes at least one of a design manual allowed mismatch, a scribe line to die allowed mismatch, and line to line allowed mismatch; and determining that products from the one or more different manufacturing lines meet the allowed parametric match by taking measurements from the products manufactured on the one or more manufacturing lines and comparing with macros placed on the product template to determine that the products from the one or more different manufacturing lines have a common parametric footprint with the product template; qualifying the products from the one or more manufacturing lines which meet the allowed parametric match, and re-centering manufacturing process for the products from the one or more manufacturing lines which do not meet the allowed parametric match until the products from the one or more manufacturing lines meet the allowed parametric match.
