Abstract A methodology is presented for generating compact models of substrate noise injection in complex logic networks. For a given gate library, the injection patterns associated with a gate and an input transition scheme are accurately evaluated using device-level simulation. Assuming spatial independence of all noise generating devices, the cumulative switching noise resulting from all injection patterns is efficiently computed using a gate-level event-driven simulator.

Abstract Techniques are presented to compactly represent substrate noise currents injected by digital networks. Using device-level simulation, every gate in a given library is modeled by means of the signal waveform it injects into the substrate, depending on its input transition scheme. For a given sequence of input vectors, the switching activity of every node in the Boolean network is computed.

Characterization of the substrate noise spectrum for mixed-signal ICsIn mixed-signal integrated circuits, interference between digital noisy and sensitive analog/RF circuits is a challenging performance issue. The high cost of chip fabrication requires accurate simulation of the circuits’ performance versus signal and noise integrity. In this paper, a substrate crosstalk noise analysis flow is described and the characteristics of the substrate noise coupling mechanism are analyzed. The proposed noise integrity aware simulation flow properly estimates the substrate coupling effect and predicts the analog/RF victim circuit performance degradation due to noise coupling mechanisms. The methodology is implemented seamlessly in the current standard virtuoso-based design suite and is used in parallel with any commercial design tool, compatible with the standard analog/RF simulation process. The efficiency of the proposed methodology is validated by a full substrate crosstalk aware system on chip vehicle, designed in an RFCMOS 65 nm process. Silicon substrat...
