| 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 \ |
