如何用lua序列化下面的url？
“匹配”可以吗？

解决方法

试试这个：

library IEEE;
USE IEEE.STD_LOGIC_1164.ALL;
USE IEEE.NUMERIC_STD.ALL;
USE IEEE.STD_LOGIC_UNSIGNED.ALL;
---------------Entity--------------
Entity sinx is
      PORT ( 
                CLK      : in   std_logic;
                x  : in   Signed (9 downto 0);
            answer     : out  signed (9 downto 0) );              
End sinx;
---------------Architecture Decleration---------
Architecture Behavioral of sinx is

signal fact2  :  Signed (19 downto 0)   :=  (Others => '0') ;   
signal fact3  :  Signed (29 downto 0)   :=  (Others => '0') ;   
signal s1     :  Signed (59 downto 0)   :=  (Others => '0') ;   
signal fact5  :  Signed (49 downto 0)   :=  (Others => '0') ;
signal s2     :  Signed (99 downto 0)   :=  (Others => '0') ;   
signal fact7  :  Signed (69 downto 0)   :=  (Others => '0') ;   
signal s3     :  Signed (139 downto 0)  :=  (Others => '0') ;
signal fact9  :  Signed (89 downto 0)   :=  (Others => '0') ;
signal s4     :  Signed (179 downto 0)  :=  (Others => '0') ;
