Synthesized Summary
While it represents a significant step in automating asynchronous design within its era and niche, its dependence on a non-standard input language, the inherent challenges of the self-timed paradigm, and the potentially inefficient implementation of variables and synchronization limit its direct actionable potential for high-impact modern research compared to established synchronous HLS flows.
It serves primarily as a historical example of a specific approach to asynchronous compilation.
Optimist's View
Skeptic's View
The paper's core relevance is tied to a very specific, now largely marginalized, intersection of research areas: compiling a particular variant of CSP directly to asynchronous (self-timed) VLSI circuits.
This paper likely faded because its value was primarily confined within the niche of asynchronous circuit research and arguably didn't offer a compelling enough advantage to overcome the practical barriers to asynchronous design adoption.
The paper acknowledges significant technical challenges, most notably the "isochronic fork" problem (Chapter 4), which highlights a fundamental mismatch between the idealized model (instantaneous signal distribution) and physical reality (wire delays).
Current HLS tools, while targeting synchronous hardware, achieve the goal of compiling higher-level behavioral descriptions into hardware, often from languages more familiar to software engineers (C++, SystemC).
