Abstract :
A new method for designing single rail asynchronous circuits is studied. It utilises additional circuitry to monitor the activity of nodes within combinational logic blocks. When all transitions have halted a completion signal is generated. Details of the circuit and design methodology are given and the influence of glitches on the proposed circuit is discussed. Three different levels of granularity are investigated. Experimental physical layout of the circuit with extracted and back-annotated simulation results is provided. The proposed approach results in faster operation than synchronous circuits with minimum circuit overhead incurred
