A structural discipline for constructing speed-independent (hazard-free) circuits based on canonical chains of set-dominant and reset-dominant latches is proposed. The method can be applied to decompose complex asymmetric C-gate generated by logic synthesis from Signal Transition Graphs, and to map them into a restricted gate array ASIC library, such as IBM SA-12E that consists of logic gates with maximum four inputs and includes AO12, AOI12, OA12 and OAI12. The method is illustrated by new implementations of practically useful asynchronous circuits: a toggle element and an edge-triggered latch controller.
