Automatic Synthesis of Interface Circuits from Simplified IP Interface Protocols and Matching Information

Abstract

Automatic interface synthesis generates product FSM from interface FSMs of IP. But complicated interface FSM may lead to a very large product FSM which results in large interface circuits. So we propose a simplified interface FSM description scheme where transactions are represented based on transfers and several parameters. In addition, the interface circuit is generated by considering only those transactions which are involved in matching information. By virtue of matching information we could generate the interface circuits which may not be easy to generate with previous methods due to inability to consider the differences in characteristics of interface protocols of IP. Through experiments we observed that our description scheme helps reduce the size of interface circuits and our synthesis method correctly generates the interface circuits between IPs with different characteristics.
