A method of testing a die having a non-testable circuit, where the non-testable circuit is logically incomplete and forms part of a logically complete multiple tier circuit. The method includes reconfiguring a tier-to-tier input point or tier-to-tier output point associated with a primary path of the non-testable circuit to create a logically complete secondary path for the tier-to-tier point such that the non-testable circuit can be tested. Testable dies and methods of preparing such dies are also provided. |
