Probabilistic simulation for reliability and average power estimation
… of circuit components accentuated reliability problems such as electromigration in the power buses, hot-carrier degradation of transistors, and excessive power consumption, which ultimately resulted in chip failures. This brought forward the need for simulation tools that would …

Reliable Data Processing Enabled By Program Analysis
… results or even faulty conclusions. We call them reliability problems. ^ We consider the reliability problems that are caused by two kinds of errors. The first kind of errors includes input and parameter errors, which originate from the external physical environment. We call these external errors. …

Atomistic model of void nucleation and growth during electromigration
… electromigration is among the most significant reliability problems in the semiconductor industry. To help gain a better understanding of the atomistic processes involved in void formation under electromigration conditions we have used the Embedded Atom Method (BAM) to determine the structure …

Hot-carrier reliability of MOSFETs at room and cryogenic temperature
Hot-carrier reliability is an increasingly important issue as the geometry scaling of MOSFET continues down to the sub-quarter micron regime. The power-supply voltage does not scale at the same rate as the device dimensions, and thus, the peak lateral E-field in the channel increases. Hot-carriers, …

Toward high-level synthesis of reliable circuits through low-cost modulo shadow datapaths
… shrinking to the atomic scale, a plethora of new reliability problems presents a barrier to continued Moore’s law scaling. Traditional modular redundancy techniques with 2x and 3x area cost eliminate the area reduction benefits of such scaling. In this study, we take a partial redundancy approach …
