Integrating simulation models created using different simulation systems is a common problem when constructing virtual platforms. Different companies and different departments can create models, and virtual platforms for different purposes using different tools. There are also existing models that need to be integrated into new tools, or the other way around. The simulators can be quite different in details, even in the case of transaction-level models. We present work in integrating SystemC transaction-level models into two typical full-system simulation environments, QEMU and Simics. We present issues in reconciling the semantics of the different platforms, and our proposed solutions. In the Simics integration, we additionally enable checkpointing in the models, based on the Simics checkpoint mechanism.

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, and should be in place to support the modelling of those busses and IO structures. We will present the infrastructure that we have built, and indicate where our future work will hea.
