Abstract: An integrated circuit (IC) die has an on-die parametric test module. A semiconductor substrate has die area, and a functional IC formed on an IC portion of the die area including a plurality of circuit elements configured for performing a circuit function. The on-die parametric test module is formed on the semiconductor substrate in a portion of the die area different from the IC portion. The on-die parametric test module includes a reference layout that provides at least one active reference MOS transistor, wherein the active reference MOS transistor has a reference spacing value for each of a plurality of context dependent effect parameters. A plurality of different variant layouts are included on the on-die parametric test module. Each variant layout provides at least one active variant MOS transistor that provides a variation with respect to the reference spacing value for at least one of the context dependent effect parameters.

Abstract: Various embodiments provide an integrated circuit (IC) design method and design kit for reducing context variations through design rule restrictions. The design method can be applied to components (e.g., analog blocks) with a context variation in an IC design. By drawing a cover layer over such components, context-variation-reduction design rule restrictions can be applied to reduce the context variations.

Abstract: A system and method for determining transistor model parameters that account for layout-dependent features in the transistor being modeled, and also in neighboring devices in the same integrated circuit. A computer-readable expression of the integrated circuit layout is retrieved, and active and gate layers in that expression extracted. For a transistor being modeled, its active regions are analyzed to determine whether these regions have a complex shape. Model parameters are derived based on volume effects of the complex shaped active regions. Neighboring active regions that affect parameters of the transistor being modeled are also identified and their effective depth determined. Strain effects due to complex shaped active regions and neighboring elements are thus included in the transistor model.
