利用verilog实现单片机的反向设计。编程环境为modelsim6.0

library verilog;
use verilog.vl_types.all;
entity rom_addr_sel is
    port(
        clk             : in     vl_logic;
        rst             : in     vl_logic;
        \select\        : in     vl_logic;
        des1            : in     vl_logic_vector(7 downto 0);
        des2            : in     vl_logic_vector(7 downto 0);
        pc              : in     vl_logic_vector(15 downto 0);
