Efficient and Extensible Transaction Level Modeling Based on an Object Oriented Model of Bus Transactions

Transaction level modeling (TLM) aims at abstract description and highperformance simulation of bus-based System-on-Chip (SoC) platforms. While languages and libraries providing the necessary basic modeling mechanisms are 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 performance measurements show that by abstracting from signal-level data representations, a cycle-accurate object-oriented model can achieve performance close to models on cycle-approximate level.
