2005
Electronical Notes in Theoretical Computer Science
We demonstrate the feasibility of our approach by automatically detecting errors due to delay sensitivity and deadlock in simple asynchronous hardware components. ...
Formal verification is increasingly important in asynchronous circuit design, since the lack of a global synchronizing clock makes errors due to concurrency (e.g., deadlocks) virtually impossible to detect ...

Click-Based Asynchronous Mesh Network with Bounded Bundled Data
2018

We believe that with the non-delay-branch designs, our asynchronous mesh network could offer 10.1M routes per second for a 1 × 1 network and 5.33M routes per second for 2 × 2 or 5.06M for 4 × 4 networks ...
