Multi-Layer Package Power/Ground Planes Synthesis with Balanced DC IR Drops: A Game-Theoretic Optimization Approach

Published in IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems (TCAD), Paper, 2025

As one of the earliest works focusing on the design automation of power/ground plane in packages, this paper introduces a game-theoretic optimization method aimed at evenly mitigating DC IR drops across the multi-layer package power/ground planes. Experimental results demonstrate that the maximum DC IR drop and the IR drop difference can both be significantly reduced.

Combinatorial-Coding-Based High-Performance Microfluidic Control Multiplexer: Design, Synthesis, and Adaptation

Published in IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems (TCAD), Paper, 2024

This is the extension of our ICCAD’ 22 CoMUX paper. This paper offers users a comprehensive guide to the design, synthesis, and adaptation of CoMUX. Experimental results show that CoMUXes can reliably address more independent control channels with fewer resources. The proposed adaptation method is also tested to be capable of significantly reducing area usage, total length of control channels, and the risk of having defects.

RABER: Reliability-Aware Bayesian-Optimization-based Control Layer Escape Routing for Flow-based Microfluidics

Published in The 43rd ACM/IEEE International Conference on Computer-Aided Design (ICCAD), Paper, 2024

This paper presents a practical and novel control layer escape routing methodology, which can efficiently connects microvalves to user-specified boundaries. This is very helpful to help designers place ports on boundaries of designs, thereby benefitting experiments. Moreover, this is also supportive to integrate our MUX works into users’ circuits.

Late Breaking Results: Efficient Built-in Self-Test for Microfluidic Large-Scale Integration (mLSI)

Published in The 61st Design Automation Conference (DAC), Paper, 2024

This paper presents a built-in self-test (BIST) method that drastically improves the test efficiency for microfluidic large-scale integration (mLSI) chips. Given n to-be-tested control channels, the proposed method reduces the number of test patterns for blockage and leakage tests from up to n/2 to 1, and from up to log2(n+1) to up to log2(X(G)+1), respectively, where X(G) denotes the vertex chromatic number of a graph G consisting of n vertices.
