Attacking complexity in logic synthesis of asynchronous circuits
Most of the microelectronic circuits fabricated today are synchronous, i.e. they are driven by one or several clock signals. Synchronous circuit design faces several fundamental challenges such as high-speed clock distribution, integration of multiple cores operating at different clock rates, …

CAD Tool Design for NCL and MTNCL Asynchronous Circuits
… convert Boolean designs into an ultra-low power asynchronous design methodology called MTNCL, which combines multi-threshold CMOS (MTCMOS) with NULL Convention Logic (NCL) systems. MTNCL provides the leakage power advantages of an all high-Vt implementation with a reasonable speed penalty …

Technology Mapping, Design for Testability, and Circuit Optimizations for NULL Convention Logic Based Architectures
<p>Delay-insensitive asynchronous circuits have been the target of a renewed research effort because of the advantages they offer over traditional synchronous circuits. Minimal timing analysis, inherent robustness against power-supply, temperature, and process variations, reduced energy …

Testing of delay-insensitive circuits using protocol extraction strategies
Delay-insensitive (DI) circuits are asynchronous circuits whose functional correctness is independent of the delays in their components and the interconnecting wires. The environment and circuit module follows a specified usage protocol, sometimes called handshake signals. It has been believed that …

Synthesis heuristics for large asynchronous sequential circuits
"Many well-known synthesis procedures for asynchronous sequential circuits produce minimal or near-minimal results, but are practical only for very small problems. These algorithms become unwieldy when applied to "large" circuits with, for example, three or more input variables and twenty or more …
