SRAM dynamic stability: theory, variability and analysis
Wei Dong,Peng Li,Garng M. Huang +2 more
- 10 Nov 2008
TL;DR: The newly defined DNMs not only capture key SRAM nonlinear dynamical characteristics but also provide valuable design insights and show how system theory can be exploited to develop CAD algorithms that can analyze SRAM dynamic stability characteristics three orders of magnitude faster than a brute-force approach while maintaining SPICE-level accuracy.
WavePipe: parallel transient simulation of analog and digital circuits on multi-core shared-memory machines
TL;DR: This work presents a parallel transient simulation methodology and its multi-threaded implementation for general analog and digital ICs, and exploits coarsegrained application-level parallelism by simultaneously computing circuit solutions at multiple adjacent time points in a way resembling hardware pipelining.

Tracing SRAM separatrix for dynamic noise margin analysis under device mismatch
Garng M. Huang,Wei Dong,Yenpo Ho,Peng Li +3 more
- 01 Sep 2007
TL;DR: By applying a rigorous nonlinear system theory, this work presents an efficient separatrix tracing technique that can accurately determine the separatrix via fast transistor-level transient simulation and is shown to be up to thousands times faster than a brute-force approach.

MAPS: multi-algorithm parallel circuit simulation
Xiaoji Ye,Wei Dong,Peng Li,Sani R. Nassif +3 more
- 10 Nov 2008
TL;DR: A novel multi-algorithm parallel circuit simulation approach (MAPS) and its multi-core implementation to expedite one of the most fundamental CAD applications: transistor-level transient circuit simulation.
Hierarchical Harmonic-Balance Methods for Frequency-Domain Analog-Circuit Analysis
TL;DR: H hierarchical HB methods are proposed wherein robust preconditioning is provided via solution of a set of approximate linearized HB problems of progressively smaller size across multiple levels of the problem hierarchy, and it has been shown that the proposed approaches can achieve up to 10 runtime speedup over the popular BD preconditionser and robust convergence even for strongly nonlinear circuits for which the BD precondsitioner fails to converge.
