Note: By default, QEMU disables
any devices for which there is no model available. For this reason it is not
possible to use QEMU to test your own customized IP cores (unless you develop C/C++
models for them according to QEMU standard).
For more information on Xilinx® IP models supported by QEMU, see Xilinx Quick Emulator User Guide: QEMU (UG1169).
