Here's one: https://www.researchgate.net/profile/Jordi_Cortadella/publication/220340047_Design_Automation_of_Real-Life_Asynchronous_Devices_and_Systems/links/0912f50cb649a9625b000000.pdf?disableCoverPage=true https://www.researchgate.net/profile/Jordi_Cortadella/public... Here's a RTL-level approach: https://www.ndsu.edu/pubweb/~scotsmit/uncle_async_12.pdf https://www.ndsu.edu/pubweb/~scotsmit/uncle_async_12.pdf Here's one for the hybrid Globally-Asynchronous, Locally-Synchronous model: https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20050229914.pdf https://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/200502... On low-level details, here's two on asynchronous synthesis: https://ieeexplore.ieee.org/document/1327634/ https://ieeexplore.ieee.org/document/1327634/ http://orbit.dtu.dk/files/3459606/Behavioral%20Synthesis%20Nielsen%20et%20al.pdf http://orbit.dtu.dk/files/3459606/Behavioral%20Synthesis%20N... Synthesis and verification together http://csl.yale.edu/~rajit/ps/invsynth.pdf http://csl.yale.edu/~rajit/ps/invsynth.pdf And here's a few designs from my collection: http://vlsi.cornell.edu/~rajit/ps/dram.pdf http://vlsi.cornell.edu/~rajit/ps/dram.pdf https://escholarship.org/uc/item/23n9d4pj https://escholarship.org/uc/item/23n9d4pj https://pdfs.semanticscholar.org/2c07/66eda008b59750eb1e789f30ddf74e626d66.pdf?_ga=2.220371544.1775183820.1531841368-175043328.1531583283 https://pdfs.semanticscholar.org/2c07/66eda008b59750eb1e789f... Note: That's an earlier one I'm including since older nodes are still available via MOSIS and Europractice. Any patents are probably expired. It got first pass in silicon, too. And I just randomly found this paper that has an optimization algorithm to reduce the area and latency disadvantages of asynchronous circuits: http://www.cs.columbia.edu/~cjeong/papers/aspdac07.pdf http://www.cs.columbia.edu/~cjeong/papers/aspdac07.pdf
