I see. I am not sure how to bring configurability to Qemu. There is the possibility to describe the hw PTF with DTC/DTB or something similar. I think some people were working on it for the ARM Qemu platform (but I am not sure what happened to this initiative). Now in the meantime, would it make sense to move leon3_generic to a tsim compatible platform? This would allow to validate the same software on the 2 simulators (obviously it would not be compatible with your specific FPGA version for now). JC
