Open-Source QEMU and RTL Co-simulation
summary
AMD‑Xilinx uses QEMU as a fast transaction‑level virtual platform glued to SystemC/TLM and RTL simulators so software boots before silicon. The open source libsystemctlm‑soc and RemotePort bridges connect QEMU + Verilator models and VFIO FPGA bridges to replay AXI/PCIe transactions. Moving parts into QEMU increases emulator capacity by about 60% and speeds software‑driven RTL tests up to a 240x speedup. A live RTL Ethernet LMAC prototype runs, produces PCAP traces, and supports cycle‑level signal inspection via libsystemctlm-soc.
