Structural methods for the synthesis of speed-independent circuits
Most existing tools for the synthesisof asynchronouscircuits from Signal Transition Graphs (STGs) derive the reachability graph for the calculation of logic equations. This paper ...

Detecting State Coding Conflicts in STG Unfoldings Using SAT
Abstract. The behaviour of asynchronous circuits is often described by Signal Transition Graphs (STGs), which are Petri nets whose transitions are interpreted as rising and falling...

Logic Synthesis for Asynchronous Circuits Based on Petri Net Unfoldings and Incremental SAT
The behaviour of asynchronous circuits is often described by Signal Transition Graphs (STGs), which are Petri nets whose transitions are interpreted as rising and falling edges of...

A Polynomial-Time Algorithm for Checking Consistency of Free-Choice Signal Transition Graphs
Signal Transition Graphs (STGs) are one of the most popular models for the specification of asynchronous circuits. A STG can be implemented if it admits a so-called consistent an...

Improved Decomposition of STGs
Signal Transition Graphs (STGs) are a version of Petri nets for the specification of asynchronous circuit behaviour. It has been suggested to decompose such a specification as a...

Output-Determinacy and Asynchronous Circuit Synthesis
Signal Transition Graphs (STG) are a formalism for the description of asynchronous circuit behaviour. In this paper we propose (and justify) a formal semantics of nondeterministic...

State encoding of large asynchronous controllers
A novel method to solve the state encoding problem in Signal Transition Graphs is presented. It is based on the structural theory of Petri nets and can be applied to large specifi...
