Query: Comments on "Dual-rail asynchronous logic multi-level implementation"   In this research communication, we comment on "Dual-rail asynchronous logic
multi-level implementation" [Integration, the VLSI Journal 47 (2014) 148-159]
by expounding the problematic issues, and provide some clarifications on
delay-insensitivity, robust asynchronous logic, multi-level decomposition, and
physical implementation.
