This two-part article aims to provide both a short historical and technical overview of
asynchronous design, as well as a snapshot of the state of the art. Part 1 covered …

Handshake circuits form a special class of asynchronous circuits that has enabled the
industrial exploitation of the asynchronous potential such as low power, low electromagnetic …

A synchronous mode as well as a scan mode of operation are added to a large class of
asynchronous circuits, in compliance with LSSD design rules. This enables the application …

Even though the asynchronous design methodology is considered to be a promising
solution to upcoming challenges of designing complex integrated circuits (ICs), it is not …

A new test method for self-timed circuits is presented that only uses multiplexers to make the
majority of combinational feedback loops testable. Combinational feedback loops are …

Asynchronous design offers a solution to the interconnect problems faced by system-on-chip
(SoC) designers, but their adoption has been held back by a lack of methodology and …

As a class of asynchronous circuits, handshake circuits are designed to tolerate variation of
gate delays. However, certain timing constraints, such as the bundled data assumption, are …

With low power and variation-tolerant features, asynchronous have been widely used in
advanced VLSI designs. Testing asynchronous circuits has become a very important …

Various examples of a circuit and a technique for testing the circuit are disclosed herein. In
an example, the circuit includes a data input coupled to a scan multiplexer and a path select …

Despite advances in the design of asynchronous circuits, little progress has been made in
their testing or design for testability. This work proposes a new strategy for testing …
