Abstract :
To introduce the basis of asynchronous digital circuit
design in an electrical engineering curriculum, Null Convention
Logic is presented as an innovative asynchronous paradigm. The
design flow from concept to circuit implementation is discussed.
First, two completeness criteria are required for speed independency:
symbolic completeness of expression and completeness of
input. Second, threshold gates with hysteresis are primary components,
which are used to build logic gates, full adder, and registers.
As an example, a 4 4 multiplier is constructed based on these
threshold gates. Finally, an example of very-high-speed integration
circuit hardware description language (VHDL) simulation is given
to help students practice and understand the asynchronous design
methodology.
