ABSTRACT
The problem of designing asynchronous circuits where the changes in binary input signals occur independently of one another is discussed. If several input changes occur within some interval d1, the circuit behaves as though the changes were simultaneous. If consecutive changes are spaced by intervals exceeding some longer interval d2 then the circuit reacts as though a sequence of single changes had occurred. But when the spacing is between these values, the system may react in an unsatisfactory manner unless special attention is paid to the problem during the design process. Constraints imposed by this problem on the row assignment and on the delay elements are derived.
