问题一：fast_runtime.opt里本来是这个样子的 Program map
-o <design>_map.ncd; # Output Mapped ncd file
-pr b; # Pack internal FF/latches into IOBs
#-fp <design>.mfp; # Floorplan file
<inputdir><design>.ngd; # Input NGD file
<inputdir><design>.pcf; # Physical constraints file
END Program map 现在有一个教程，它说加上一句-ir在如下位置 Program map
-o <design>_map.ncd; # Output Mapped ncd file
-ir
-pr b; # Pack internal FF/latches into IOBs
#-fp <design>.mfp; # Floorplan file
<inputdir><design>.ngd; # Input NGD file
<inputdir><design>.pcf; # Physical constraints file
END Program map 然后我就生成位流文件。这时出现了这个错误：
ERROR:Xflow:1 - Line 1: parse error '-pr' unexpected.
ERROR:Xflow:64 - 1 Error(s) found in Optionfile
E:/Xilinx_practice/bsb/implementation/xflow.opt
ERROR:Xflow:40 - Errors found in flow and/or option files... Aborting!
make: *** [implementation/system.bit] Error 1 不知道为什么？ 然后我就把-pr前加了// 注释掉了，然后再生成位流文件。ok了这次 问题二： 然后我接着做下一个步骤，build all use applications. 其实就是编译TestApp_Peripheral, 这时出现了这个错误; At Local date and time: Wed Sep 12 09:52:59 2007
