Abstract: Checking the layout integrity includes the steps of receiving inputs defining a plurality of devices for a layout, generating a signature for each device in the layout, when created, from one or more parameters of the device, storing the generated signatures with the layout, receiving the stored layout and signatures, regenerating each signature for each device in the stored layout, and comparing each regenerated signature with the corresponding stored signature.
