Abstract

A method of designing a reset circuit for a digital integrated circuit (IC) layout is described. The reset circuit is designed with the intention of making it visually non-detectable in the digital IC layout by implementing the reset circuit entirely in digital elements and then using standardized digital layout cells and routing such that the reset circuit is essentially non-discernible from the digital circuitry of the IC device layout. In addition, circuit elements are designed using devices having dimensions that are essentially the same as typical digital devices in the digital IC layout.
