System and method for testing integrated circuits by determining the solid timing window

Abstract

Systems and methods are provided to determine a solid operating timing window for an integrated circuit device, and the solid operating timing window used to determine a key timing index. A method for determining the solid operating timing window is disclosed. A plurality of sets of operating parameters is generated. For each of the plurality of sets of operating parameters, the respective set of operating parameters is applied to a test environment. The integrated circuit is then operated under the applied respective set of operating parameters. A determining a data valid window is determined for the integrated circuit. The solid operating timing window for the integrated circuit is then determined using the data valid windows for the plurality of sets of operating parameters, where the solid operating timing window is defined as the logical intersection of the determined data valid windows such that the integrated circuit will return valid sample.
