Synthesis using Sequential Functional Modules (SFMs)

This paper presents a new method used in our RTL-synthesis tool to perform technology mapping with Sequential Functional Modules (SFMs) such as counters, accumulators, shift-registers, or rotators from any target or macro library. If the library contains SFMs, the method automatically recognizes them. If an RTL design contains patterns that can be implemented on SFMs, the method maps them to the SFMs found in the target library. This mapping reduces the design time by leveraging the library developer´s effort, leads to more regular and often smaller and faster designs, and helps to reduce timing and routing problems at later stages of the design process.
