Invited: Toward Accurate, Large-scale Electromigration Analysis and Optimization in Integrated Systems
Sachin S. Sapatnekar
Electromigration, a significant lifetime reliability concern in highperformance integrated circuits, is projected to grow even more important in future heterogeneously integrated s…
Supporting Higher-Order Interactions in Practical Ising Machines
Nafisa Sadaf Prova, Hüsrev Cılasun, Abhimanyu Kumar +3
Ising machines as hardware solvers of combinatorial optimization problems (COPs) can efficiently explore large solution spaces due to their inherent parallelism and physics-based d…
HETRI: Heterogeneous Ising Multiprocessing
Ahmet Efe, Hüsrev Cılasun, Hüsrev Cılasun +6
Ising machines are effective solvers for complex combinatorial optimization problems. The idea is mapping the optimal solution(s) to a combinatorial optimization problem to the min…
DROID: Discrete-Time Simulation for Ring-Oscillator-Based Ising Design
Abhimanyu Kumar, Ramprasath S., Chris H. Kim +2
Many combinatorial problems can be mapped to Ising machines, i.e., networks of coupled oscillators that settle to a minimum-energy ground state, from which the problem solution is…
Accelerating OTA Circuit Design: Transistor Sizing Based on a Transformer Model and Precomputed Lookup Tables
Subhadip Ghosh, Endalk Y. Gebru, Chandramouli V. Kashyap +2
Device sizing is crucial for meeting performance specifications in operational transconductance amplifiers (OTAs), and this work proposes an automated sizing framework based on a t…
IR-Aware ECO Timing Optimization Using Reinforcement Learning
Wenjing Jiang, Vidya A. Chhabria, Sachin S. Sapatnekar
Engineering change orders (ECOs) in late stages make minimal design fixes to recover from timing shifts due to excessive IR drops. This paper integrates IR-drop-aware timing analys…
