Abstract
若在Quartus II 7.2下啟動ModelSim-Altera 6.1g進行模擬，可能會遇到以下錯誤訊息而無法模擬成功。
Introduction
使用環境：Quartus II 7.2 SP3 + ModelSim-Altera 6.1g
Error: Can't launch the ModelSim-Altera software -- the path to the location of the executables for the ModelSim-Altera software were not specified or the executables were not found at specified path.
Error: You can specify the path inthe EDA Tool Options page of the Options dialog box or using the Tcl command set_user_option.
Error: NativeLink simulation flow was NOT successful

Error: NativeLink simulation flow was NOT successful
Solution
Step 1：
設定NativeLink路徑
Tools -> Options -> General -> EDA Tool Options：
將ModelSim-Altera的路徑設定到c:\altera\72\modelsim_ae\win32aloem
