Synthesized Summary
This paper provides a rigorous, albeit constrained by its time, framework for analyzing and optimizing asynchronous circuit performance...
However, its direct utility for modern research is severely limited because the core circuit timing models are obsolete and the approach is tied to a niche synthesis methodology.
There is no unique, actionable path offered here that is not better covered by modern, more accurate, and broadly applicable techniques or tools developed since its publication.
Optimist's View
The core ideas – representing asynchronous circuit timing using formal event-rule systems (timed directed graphs) and analytically deriving performance metrics like cycle period and latency using linear programming and cycle analysis – hold significant latent potential.
The underlying formalism of Event-Rule systems and the use of linear programming/cycle analysis on timed directed graphs are highly transferable.
Modern computing power and advanced optimization solvers can handle problem instances orders of magnitude larger and faster.
Interest in asynchronous design is growing again for low-power, fault tolerance, and specialized computing (AI/ML accelerators).
Skeptic's View
The core assumption that analytical techniques for asynchronous circuits would become a dominant paradigm shift has largely failed to materialize in the general-purpose computing landscape.
The underlying CMOS process physics have changed dramatically. Simple RC timing models (like the tau model in Chapter 7) are wildly insufficient for modern sub-nanometer processes...
The most significant reason for obscurity is likely the continued niche status of asynchronous design itself.
The optimization algorithm (subgradient with heuristics) is not the state-of-the-art for convex optimization problems.
