I’d be interested in knowing this as well. This gives some examples of async circuits: https://web.stanford.edu/class/archive/ee/ee371/ee371.1066/lectures/lect_12.pdf <https://web.stanford.edu/class/archive/ee/ee371/ee371.1066/lectures/lect_12.pdf>

Page 43, “Bottom Line” mentions that asynchronous design has “some delay matching / overhead issues”. Apparently delay matching means getting the signal outputs on two separate paths to arrive at the same time(?) Presumably overhead refers to the 2x space on the die previously mentioned, for completion detection. Pages 23-25 on “data-bundling constraints” might also highlight some other challenges. Some more current material would be interesting though...
