Synthesis using sequential functional modules (SFMs)
Samit Ray‐Chaudhuri, Michael Quayle · 1996
This paper presents a new method used in our RTL-synthesis tool to perform technology mapping with Sequen-tial Functional Modules (SFMs) such as counters, accumu-lators, shift-registers, or rotators from any target or macro library. If the library contains SFMs, the method automat-ically 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 re-duces 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. 1
