Sacrificing around 8 percent of the accuracy, TQSIM enables one or two orders of magnitude faster simulation than a reference cycle-accurate simulation when the target architecture is an ARM Cortex A15 processor. This feature enables you to model large and.

Attached with a cache simulator, a branch predictor, and a trace analyzer, the proposed technique is implemented over the popular and portable QEMU emulator, so named TQSIM (Timed QEMU-based SIMulator). TEWKSBURY, Mass. You can use Xilinx QEMU to connect and drive mixed simulation environments using the included remote-port framework. For the back-end, we developed a novel processor timing model that combines a simple-formula-based analytical model and a scheduling analysis of sampled traces so as to boost up the simulation speed with minimal accuracy loss. The QEMU Bridge converts SystemC TLM transactions to AXI and vice versa providing a fast interface for co-simulation.

The proposed simulation technique is designed in two parts the front-end provides correct functional execution of the guest application, and the back-end provides a timing model. Integration and simulation of FPGA custom IPs with software applications and drivers executing on the virtual processor in QEMU is now possible and simplified. We propose a fast cycle-approximate simulation technique for modern superscalar out-of-order processors. Timing simulation of a processor is a key enabling technique to explore the design space of system architecture or to develop the software without an available hardware.
