State encoding is one of the most difficult problems in the synthesis of asynchronous controllers. This paper presents a method that can solve the problem of large controllers specified with signal transition graphs. The method is based on the structural theory of Petri nets and uses integer-linear programming to insert state signals in locations that guarantee the consistency and absence of critical...
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 specifications with hundreds of signals. This new method opens the door to incorporate logic synthesis in the design flow of large control circuits obtained from high-level specifications. The experimental results validate the quality...
