1. Clone the sail-riscv repository:

   $ git clone https://github.com/riscv/sail-riscv.git
   

2. Add a decode target to the Makefile, providing the path to the plugin built above:

    .PHONY:
     
    +decode: $(SAIL_SRCS) model/main.sail Makefile
    +       sail -dno_cast -no_warn -plugin $(replace with path to)/riscvdecode/riscv_decode.cmxs -riscv_decode $(SAIL_SRCS)
    +
