else ledout<=led; if dp_tmp=\ dp<='0'; else dp<='1'; end if; end if; when \ if hide(4)='1' then ledout<=\ dp<='1'; else ledout<=led; dp<='1'; end if; when \ if hide(5)='1' then ledout<=\ dp<='1'; else ledout<=led; dp<='1'; end if; when others => ledout<=\ dp<='1'; end case; end if; end process;
sel<=switch; G<='0';
end Behavioral;
六、 系统硬件实现与调试
管脚分配：
NET \NET \
NET \
NET \NET \NET \NET \NET \NET \NET \NET \NET \NET \NET \NET \NET \NET \
仿真： 1、分频器
process begin clkin<='1'; wait for 1 ps; clkin<='0'; wait for 1 ps; end process;
2、闸门选择
process begin se1<='1'; se10<='0'; se100<='0'; wait; end process;
process begin f1<='1'; wait for 100 ps; f1<='0'; wait for 100 ps; end process;
process begin f10<='1'; wait for 50 ps; f10<='0'; wait for 50 ps;
end process;
process begin f100<='1'; wait for 10 ps; f100<='0'; wait for 10 ps; end process;
3、门控电路
process begin Bsignal<='0'; wait for 100 ps; Bsignal<='1'; wait for 100 ps; end process;
4、计数器
process begin count_en<='1'; wait; end process;
process begin Csignal<='1'; wait for 10 ps; Csignal<='0'; wait for 10 ps; end process;
process begin clear<='0'; wait for 10 us; clear<='1'; wait for 10 ps; end process;
