SoC Session Level Modeling using Java

Abstract

In this paper, we are inspired by similarities between system on chip (SoC) and networked systems to introduce a new modeling abstraction above transaction level modeling (TLM). We use concepts of the famous session initiation protocol (SIP) to introduce a new abstraction level for bus protocol modeling above the transaction modeling layer, namely session level modeling. Primitives of our proposed session modeling layer are directly inspired from SIP. In our modeling approach, session establishment expresses the semantics of acquiring the bus, along with the readiness of the slave device. We implemented the session level primitives using Java, a very capable language for modeling SoC, and demonstrated how such primitives could be used in multilevel modeling
