那个245的问题已经解决了。<br />又有个问题,vhdl怎么使用xilinx提供的元件库?<br />它的文档是这样说的:<br /><br />-- Component Declaration for IBUF should be placed<br />-- after architecture statement but before begin keyword<br />component IBUF<br />port (O : out STD_ULOGIC;<br />I : in STD_ULOGIC);<br />end component;<br /><br /><br />-- Component Attribute specification for IBUF<br />-- should be placed after architecture declaration but<br />-- before the begin keyword<br />-- Enter attributes here<br />-- Component Instantiation for IBUF should be placed<br />-- in architecture after the begin keyword<br />IBUF_INSTANCE_NAME : IBUF<br />port map (O => user_O,<br />I => user_I);<br /><br />可是我按照他那样作,综合都能通过,但是fit总是出错。<br />是不是要在文件开头加上 library 之类的语句????<br />但是也不知道是什么语句。<br />有人知道xilinx的技术支持电话么?告诉我一下也好。谢谢。<br /><br /> |
