... asynchronous circuits?
Most digital circuits designed and fabricated today are “synchronous”. In
essence, they are based on two fundamental assumptions that greatly simplify
their design: (1) all signals ... clock signal distributed throughout
the circuit.
Asynchronous circuits are fundamentally different; they also assume bi-
