在「从ISE中执行ModelSim仿真的过程」的第一图上的下拉选项上，有可进行仿真的Behavioral、Post-Translate、Post-Map、Post_Route四种方式可选。

在选择View的Implementation视图时，就可以选择生成这四种仿真的模型：

其生成的仿真文件目录为工程下的netgen（参见：有关NetGen生成的仿真模型）：

模拟类型	输出目录	输出目录下生成文件	工程目录下生成文件
Generate Post-Synthesis Simulation Model	netgen/synthesis	xxx_synthesis.vhd xxx_synthesis.nlf	xxx.ngc
Generate Post-Translate Simulation Model	netgen/translate	xxx_translate.vhd xxx_translate.nlf	xxx.ngd
Generate Post-Map Simulation Model	netgen/map	xxx_map.vhd xxx_map.sdf xxx_map.nlf	xxx.ncd
Generate Post-Place & Route Simulation Model	netgen/par	xxx_timesim.vhd xxx_timesim.sdf xxx_timesim.nlf	xxx.ncd

生成仿真模型时执行的命令行语句可从工程目录下的扩展名为.cmd_log文件中看出，具体的例见下：
