Built on QEMU, a widely used ARM full-system emulator, QFlex 3.0 relies on statistical sampling to cut timing simulation time by two orders of magnitude. Future releases will include enhancements to exploit multicore hosts, interoperable checkpointing to enable versatility across timing simulators, and multi-server simulation for rack-scale computing.entext::conference output::conference paper not in proceedings
