This document proposes two methods for integrating SystemC models with virtual platform simulators like QEMU and Simics: 1) A "QEMU SystemC Bridge" that synchronizes the two simulators using lazy synchronization. 2) Wrapping QEMU as a TLM-2.0 initiator to standardize the integration. Experiments showed little performance overhead (<5%) for both approaches. The techniques allow developing full virtual platforms using SystemC for device modeling.
