Logic Synthesis and Optimization for CMOS and Post-CMOS Technologies

Dewmini Sudara Marakkalage

Logic synthesis is a cornerstone of electronic design automation (EDA), facilitating the optimization of power, performance, and area (PPA) in integrated circuits. As complementary metal-oxide-semiconductor (CMOS) technology approaches its physical limitat ...

Scalable Sequential Logic Synthesis Using Observability Don’t Care Conditions

Giovanni De Micheli, Dewmini Sudara Marakkalage

Sequential logic synthesis expands the solution space compared to combinational logic synthesis by reasoning about the reachable states of memory elements, leading to better Power-Performance-Area (PPA) outcomes. As gate costs continue to rise in advanced ...

Fanout-Bounded Logic Synthesis for Emerging Technologies - A Top-Down Approach

Giovanni De Micheli, Dewmini Sudara Marakkalage

In logic circuits, the number of fanouts a gate can drive is limited, and such limits are tighter in emerging technologies such as superconducting electronic circuits. In this work, we study the problem of resynthesizing a logic network with bounded-fanout ...

Garbled Circuits Reimagined: Logic Synthesis Unleashes Efficient Secure Computation

Giovanni De Micheli, Dewmini Sudara Marakkalage, Mingfei Yu

Garbled circuit (GC) is one of the few promising protocols to realize general-purpose secure computation. The target computation is represented by a Boolean circuit that is subsequently transformed into a network of encrypted tables for execution. The need ...

Optimizing Adiabatic Quantum-Flux-Parametron (AQFP) Circuits using an Exact Database

Giovanni De Micheli, Dewmini Sudara Marakkalage

Adiabatic Quantum-Flux-Parametron (AQFP) is a family of superconducting electronic (SCE) circuits exhibiting high energy efficiency. In AQFP technology, logic gates require splitters to drive multiple fanouts and both the logic gates and the splitters are ...
