How to build it =============== Configure build for the selected nSIM target. For instance, for ARC700 nSIM target use the following defauilt configuration: $ make snps_arc700_nsim_defconfig Optionally modify the configuration: $ make menuconfig Build: $ make How to use it ============= Resulting image can be booted using ARC nSIM instruction set simulator. Free version of nSIM is available for download: - https://www.synopsys.com/cgi-bin/dwarcnsim/req1.cgi It provides nsimdrv binary for Linux that can be used stand-alone or with GDB. To run ARC700 image use the following command: $ nsimdrv \ -prop=nsim_mem-dev=uart0,kind=dwuart,base=0xf0000000,irq=24 \ -prop=icache=32768,64,2,0 \ -prop=dcache=32768,64,4,0 \ -prop=nsim_isa_enable_timer_0=1 \ -prop=nsim_isa_enable_timer_1=1 \ -prop=nsim_isa_host_timer=1 \ -prop=nsim_mmu=3 \ -prop=nsim_isa_family=a700 \ -prop=nsim_isa_atomic_option=1 \ -prop=nsim_isa_dpfp=none \ -prop=nsim_isa_shift_option=2 \ -prop=nsim_isa_swap_option=1 \ -prop=nsim_isa_bitscan_option=1 \ -prop=nsim_isa_sat=1 \ -prop=nsim_isa_mpy32=1 \ -prop=isa_counters=1 \ -prop=nsim_isa_pct_counters=8 \ -prop=nsim_isa_pct_size=48 \ output/images/vmlinux
