Most approaches to interface synthesis take two interface FSMs including transactions or burst, derive a product FSM and generate an interface circuit from the product FSM. With these methods, it could be difficult and complicated to describe interface FSM of IP especially when IP has many transactions. Additionally, such descriptions may lead to a very large product FSM which results in large interface circuits. We propose a simplified interface FSM description scheme where transactions are represented based on transfers and several parameters. Since all transactions supported by IP may not be used in the system, the synthesis algorithm is designed to consider only those transactions which are involved in parameter matching. Through experiments we observed that our description scheme helps reduce the size of interface circuits and our synthesis method correctly generates the interface circuits.
