Claim One:
1. A method, comprising: spatially associating a text label with a physical parameterized cell created at least in part from a computer assisted design database that relates the physical parameterized cell to a plurality of expected mask layers, wherein the text label is integrated into each layer of the plurality of expected mask layers and wherein the text label is indicative of a layer of the physical parameterized cell in a circuit design; converting the physical parameterized cell and the text label to a format that represents the physical parameterized cell and the text label as a plurality of drawn mask layers, wherein the text label is integrated into each layer of the plurality of drawn mask layers; generating an initial equation that performs transformational operations on the plurality of drawn mask layers to create a plurality of derived mask layers; executing the initial equation to generate the plurality of derived mask layers; and comparing a derived mask layer of the plurality of derived mask layers to the expected mask layers if the derived mask layer touches, is above, or is below a derived mask layer for the text label, wherein at least one operation is executed by an integrated circuit.
