[转帖]XST不能够综合Xilinx自己的参考设计?
我也遇到了同样的问题,请达人指点!
在网上下载的xilinx的sdram参考设计,发现使用synplify综合的。但是我用xst综合src目录下的vhdl源文件,会报告说: WARNING:Xst:766 - D:/HITSXPersonal/XilinxDev/xsdram/src/sdrm.vhd line 238: Generating a Black Box for component . WARNING:Xst:766 - D:/HITSXPersonal/XilinxDev/xsdram/src/sdrm.vhd line 245: Generating a Black Box for component . WARNING:Xst:766 - D:/HITSXPersonal/XilinxDev/xsdram/src/sdrm.vhd line 250: Generating a Black Box for component . WARNING:Xst:766 - D:/HITSXPersonal/XilinxDev/xsdram/src/sdrm.vhd line 254: Generating a Black Box for component . WARNING:Xst:766 - D:/HITSXPersonal/XilinxDev/xsdram/src/sdrm.vhd line 260: Generating a Black Box for component . ........ 然后就是ISE产生一个错误: FATAL_ERROR:Xstortability/export/Port_Main.h:127:1.13 - This application has discovered an exceptional condition from which it cannot recover. Process will terminate. To resolve this error, please consult the Answers Database and other online resources at http://support.xilinx.com.

发现是顶层设计文件中使用了 component CLKDLL component IBUF component BUFG 等等primitive,但是有使用 library UNISIM; use UNISIM.VCOMPONENTS.ALL; 为什么还是认为综合成了黑箱子呢?而且最后还有一个错误,综合不了。这可是xilinx自己的参考设计阿。总不能只能用synplify综合吧? |
