Summary: 
This paper proposes an ASIC design support tool set for non-pipelined asynchronous circuits with bundled-data implementation. This tool set consists of seven tools to automate design processes of bundled-data implementation such as the generation of design constraints, timing verification, and delay adjustment considering a given latency constraint. With the proposed design flow which combines the proposed tool set and commercial CAD tools, most of design processes from an RTL model is fully automated. In the experiments, to show the effectiveness of energy consumption in bundled-data implementation compared to synchronous counterpart, this paper synthesizes several circuits with a latency constraint which is generated from the synchronous counterpart with the minimum clock cycle time.
