This paper presents a gate delay estimation method that takes into account dynamic power supply noise. We review STA based on static IR-drop analysis and a conventional method for dynamic noise waveform, and reveal their limitations and problems that originate from circuit structures and higher delay sensitivity to voltage in advanced technologies. We then propose a gate delay computation that overcomes...
This paper analyzes the impact of simultaneous switching noise (SSN) on the timing behavior of CMOS digital blocks. The concept of instantaneous transfer function is introduced to interpret noisy signals and perform timing measurements on such signals. It is shown that the average swing during switching is the key parameter to predict the noise impact on the delay of a logic path, whereas the peak...
The implementation of complex functionality in low-power nano-CMOS technologies leads to enhance susceptibility to parametric disturbances (environmental, and operation-dependent). The purpose of this paper is to present recent improvements on a methodology to exploit power-supply voltage and temperature variations in order to produce fault-tolerant structural solutions. First, the proposed methodology...
In this paper, we investigate optimum radiation hardened by design (RHBD) for use against single-event transients (SET) using low-pass filters (LPF) including RHBD techniques against single-event upsets (SEU) for sequential logic in 45 -nm technology in a terrestrial environment. Three types of LPF were investigated regarding their SET pulse immunities, area penalties, and performance penalties. We...
