Abstract: In this paper we present a generic interconnect fabric for transaction level modelling tackeling three major aspects. First, a review of the bus and IO structures that we have analysed, which are common in todays system on chip environments, and require to be modelled at a transaction level. Second our findings in terms of the data structures and interface API's that are required in order to model those (and we believe other) busses and IO structures. Third the surrounding infrastructure that we believe can, a… Show more

Abstractlevel modeling (TLM) aims at abstract description and highperformance simulation of bus-based System-on-Chip (SoC) platforms. While available, there is ongoing discussion on modeling styles for their usage. This contribution employs object-oriented modeling of transaction data and bus protocols, targeting at better extensibility and reuse of models. Our simulation perKeywords: Transaction-Level Modeling, SystemC, Object-Oriented, Embedded Systems INTRODUCTIONEmbedded systems and systems on chip integrate an increasing number of processor nodes and complex communication structures. It is an essential design task to model these systems prior to their implementation. This enables an early validation of system architecture concepts, exploration of architectural alternatives, and performance evaluation. Modeling on register transfer level (RTL) is no longer an option due to the complexity, inflexibility, and low simulation performance of the resulting models. Transaction level modeling has been devised as an alternative.One key principle of TLM is to perform communication by function calls rather than via signal communication. The other is to exchange information on a coarser level of granularity compared to low-level signals. With these constraints, bus based systems can be described at different TLM abstraction representations, a cycle-accurate object-oriented model can achieve perforTransaction formance measurements show that by abstracting from signal-level data

This chapter presents a contribution to the methodology of transaction-level modelling (TLM) based on SystemC and the TLM standard of the Open SystemC Initiative (OSCI). Different from previously published approaches to the use of TLM in conjunction with SystemC, we employ object-oriented features to represent transactions, namely an inheritance relationship of transaction classes, transaction polymorphism, and dynamic binding of transactions to methods of SystemC modules. Advantages of this new modelling style include reduced programming effort for transaction dispatch, easier extensibility, and guaranteed consistency. The extension of a simple transaction model to cover burst transactions is demonstrated. We make use of concepts adapted from the concurrent object-oriented design pattern known as active object. Our approach allows to fully utilize SystemC / TLM features and is in no conflict with the standardized aspects of this methodology.
