1、问题一：编译xilinx仿真库在网上搜了无数帖子，结合自己数小时的实践，终于搞定了Xilinx仿真库。测试环境：WindowsXP3，XilinxISESuite10.1，ModelSimSE6.5c使用ISE自带的库生成工具是最方便的方法。首先打开ISE，在Edit->Preferences...->ISEGeneral的IntergratedTools的ModelTechSimulator中指定Modelsim.exe的实际安装路径。（在这里我的路径是D:Workmodeltech_6.5cwin32modelsim.exe，请根据自己的实际情况更改）。OK以后退出I

2、SE。然后到ModelSim安装目录下找到ModelSim.ini文件，右键将其只读属性去掉，确定。按下WIN+R，输入compxlibgui后回车，这其实就是自带的工具SimulationLibraryCompilationWizard。点击Selectsimulator，选中ModelSim。检查路径正确了以后选Next。再Next，建议再Next，或者根据自己的实际需要选择FPGA/CPLD的具体型号。继续Next，在Maponlytoexistingpre-compiledlibraries前打上勾，在OutputDirectoryformodelsim.inifileu

3、singmappedlibraries中选择modelsim安装根目录modelsim.ini所在的路径，这一步很重要。再点击Next就开始编译了。最后把ModelSim.ini文件的只读属性改回去，万事OK……问题二：Helloall,WheneverIneedtolookatafilteroutput(oranyDSPcore),IusedtodefinearealsignalandassignittowhatIwanttoexamine,roughlysomethinglikethis:dac_real_out<=hex2real(dac_holder,12.0);wher
